|Mac Mini Owner Reports on Dim Analog Video
Reports last Updated: 8/10/2005
This page has reader feedback from users of Apple's Mac Mini regarding the issue if dim (or low contrast) Analog video. There's a thread at Apple's forums where Mini owners originally reported dim (analog) video w/VGA adapters/displays. I'm not sure if it's a uniform issue (in all Minis) or just certain builds but a reader said according to german Ct magazine (print version) tests, the analog video output level was below 530mV (below VESA standards) See bottom of page for links to other Mac Mini related articles and docs.
Reader Reports on Analog Video: (most recent first.)
If you've used a Mini with a VGA (analog) display, let me know if you've noticed dim video or not. (Include info on your display brand/model as some VGA/Analog displays seem to show this more than others.) Also note if you're using a KVM switch (if so try a direct connect although most noted this didn't help). Thankfully not every
owner saw the problem with their specific VGA display. (If you have another Mac or PC system - try comparing the VGA display brightness/contrast to the Mac Mini. Some monitors apparently don't show the problem. Note: Apple has posted a kbase doc on the issue with some
general things to check first.)
I've been reading with great interest this thread on the Mini dim video
issue. I purchased from the Apple Australia webstore a week ago, a new
"revised" Mini: 1.42GHz, 512 ram, Airport, Bluetooth, ComboDrive, and am
experiencing the same thing - a dim, washed out picture. I'd specifically
waited for this "revised" model, as I'd read reports before about issues
with the graphics (specifically DVI artifacts, and also mention of this
(brightness issue w/Analog video, although
some analog monitor owners didn't notice it and there were some tips that helped some here.
The DVI issue was reported by some owners, usually at higher res. See reports below-Mike)
and had hoped that the second generation Mini would have
any bugs ironed out. It seems that's not the case. I noticed the dimness
first when switching between the mini and a Windows XP machine using a
Belkin KVM, connected to an older 17" CRT ("Digital" brand, model VRT17-H4)
monitor. Tried all the adjustments, calibrations, but couldn't get it right
- the Windows picture was just brighter and more vivid.
Today I've borrowed a Philips 170B LCD display, and hooked that up with a direct connection
(bypassed the KVM) into the analogue VGA connection and there's no
difference. Unfortunately I didn't borrow the DVI cable for the monitor, as
it does have a DVI input, so I'll try that soon and see if it makes any
I have to say, I'm pretty disappointed, as it's an otherwise fantastic
little system. I bought this to do graphics work on, so I'm pretty eager to
resolve this issue. Might have to make a call to Apple. I wonder if anyone
with this problem has successfully returned a mini because of it,
and had a replacement that's better?
I don't remember anyone reporting a replacement helped (but I can't remember
all the reports). Some did say that contrast, calibration, etc. helped but
it was not a universal fix for everyone. A DVI monitor would be a better choice
although some have noted display issues at higher res at least.
Another Note on Univ. Access Contrast Settings:
(added 7/27/2005 - updated 8/1/2005)
"I have a Mac Mini (1.42) w/ 512K/Superdrive, hooked up via VGA to a Dell
2005FP (previously a Dell 17"). I also have a PC on DVI on that monitor.
As many have noted, I also had the dim video on the Mini, and I tried
the Universal access tip, but originally found it to be unsatisfying.
Then, I ran the display calibrator, but on the very first screen, when I
turned the brightness and contrast on the screen up, I still couldn't get
the image to where it was "supposed" to be (barely seeing the oval).
With the calibrator still on screen, I then opened up universal access
and began adjusting that...well, wouldn't you know it, but with a tiny
bump on the slider I was able to fine tune the image on that very first
page using the univ. access slider in addition to the brightness and
contrast controls on the monitor itself. Now, I have my brightness and
contrast set to ~50%, and the image looks very good.
It's not perfectly color calibrated, as I discovered yesterday...that's
something I'll need to work on. The images on screen are a bit brighter
than what comes out of my printer. But viewing on-screen images is a joy
once again, and compared to the PC, I certainly wouldn't call the video
(I asked if this LCD display had a 1920 x 1200 native res-Mike))
Yes it is correct. I just checked: Apple only says on their website that
the mini support 1920x1080 using the VGA output (a fact that might not be noticed fully by some
The 1920x1200 res (my LCD native res) is only supported via DVI which has
the flickering/tearing problem in that res of course...
See below for an older post on Notes on Universal Access Contrast Setting.
"Bought a 1.42 GHz Mini and connected a 17" LG Flatron F700P without
any problems. I tested the resolutions 1920x..., 1600x1200,
1440x...., 640x480, everything OK.
(I asked if the monitor was Analog/VGA or DVI - as some
DVI users of high-res displays reported some display glitches (see
report below from 23in HP LCD user for instance) Not every Analog
display user had the dim video issue, but more than a few did.-Mike)
VGA connection, and yes, it's 17". I've been looking a lot for
something with a better resolution than just a little bit more than
my aging iMac G3 but still fitting on my desk ;-). It supports
1920x1440@60Hz, 1600x1200@75Hz and 1400x1050@85Hz.
"Hi Mike, i just bought a brand new Macmini 1.2GHz 1GB to use it with my 23" HP 2335. And
yes there is the dim VGA analog problem and its even worse: I am running
the display on the VGA input on 1920x1200x32 (the display's real resolution) since
the DVI output has the also known problem of generating many horizontal
artifacts like flickering stripes. I thought i go for the VGA analog then since i
connect a second linux box to the monitor's DVI input anyway.
But besides the very dim setting which I can not solve using a different input voltage (the monitor doesn't
support it), the monitor loses synch once in a while depending on -well i am
not sure- what you do on the desktop. Sometimes opening a new website in firefox
or starting iSight and bang: the picture is gone. All you see then is a blue screen
(yes really a blue screen ;) where the last picture that was in the framebuffer is
arbitrary shown every 5-10 seconds. Now all you can do is to reconnect the mini via DVI and back to
VGA and the picture is back...
The apple store where i bought it could not help (and didn't hear about
these problems). As i found out, there are two shareware progs "DisplayConfigX" and
"SwitchResX" (both linked in the FAQ's Displays/Monitors section here) which are known to help with the DVI problem by changing the DVI's refresh rate, but with the VGA it has to be found out (did anyone try? The problem with
"DisplayConfigX" is you have to buy it first to enable the high res support). As one writer
already said: maybe a VGA enhancer (booster/amplifier) would help...but this is a little annoying since we all
bought a product which should run according to its specs...
Personally I'd try the Mini and the Display to a local Apple store
and demo the problem to them. (And get a refund for the system hopefully.)
"I have two Dell M770 17" monitors. Both exhibit dim video when
attached to the Mini. Both are very crisp and bright when attached to
a BW G3 tower. Sort of disappointing. There are no controls I know of
that can enhance the video level.
A few have said a monitor calibration (in OS X) helped but it's not been a fix for
"Mike, Unfortunately I am experiencing the dimming problem as well. Even though
this is my first Mac, I noticed the screen seemed dark and somewhat fuzzy
right away. After messing with the display settings, I realized that it
must be my monitor. I have an Envision EN-910e CRT. I've tried both a
direct connection and a KVM switch, both produce the same result. The
difference is very apparent when switching between my PC and the Mini.
I'm planning to purchase a Dell LCD monitor in a few weeks, so I'm hoping to
have better luck with that. Since I'd like to use my existing KVM switch,
I'm going to try the VGA connection with the adapter (unless I can scrape
together extra cash for a DVI KVM switch)...
Personally I'd get a DVI display (although some with high res DVI displays
have also noted some glitches) or select one of the monitors that a Mini owner
reported here as not having any problems.
Feedback on Input Voltage Setting (0.7v vs 1v) (although some monitors
don't have this adjustment and I thought 0.7v was the typical standard setting, this
is in reply to a previous post on input voltage settings)
just been browsing the Mac Mini dim video thread (this page). I have a 21" Mitsubishi
Diamond Pro 91TXM (7 years old). Until 5 mins ago it was a very dim picture!
I'm using a Mac Mini. I had an old G3 attached to the monitor before &
the picture was very bright. I didn't even try adjusting it until reading
I went to the enhanced menu and changed the Video Level from 1.0 to 0.7v,
the picture is now great! Thanks for helping us out!
If any other Mini owner that reported dim analog video checks their monitor for this setting (if adjustable), let me know.
Notes on Universal Access Contrast Setting: (this was a tip from the past
originally posted on the Alum Cinema Display reports page, but that's a DVI display and higher than normal contrast setting in Univ. Access made the display quality worse readers said. Higher settings helped this reader said with the Mini's lower than VESA spec analog video level (per Ct magazine measurements) and his analog display:
"I have a 1.42 GHz Mac Mini connected to a 17" IBM G97 here at work. Before
that, I hooked the Mini up to a cheap Chinese monitor that I got new and
returned to COMPUSA. I used the adapter on both of them, and both of them
were dim. I learned about the Universal Access System Preference from the
internet (this thread, probably), used it on the IBM, and the picture looks
great.... I solved the problem by moving it up the
scale to notch position 2.25 to enhance the contrast.
"No problems here - 1.42GHz mini (arrived May 2005) with a Formac
21/700 display at 1600x1200. I've not yet tried connecting it via a
KVM as the box is my primary working machine and I tend to want to
see the display.
I'm using the Apple supplied DVI-VGA adapter, but have used a couple
of no-name ones I had lying around to see if it made any difference
which it didn't - the display is the same as it is with anything else
connected to it, i.e. very lacking in contrast till the electronics
warm up when it's fine. The monitor is 5-6 years old and was
continually in use at a design place which went to flat panels all
around (don't ask me about colour accuracy and imagesetter settings!)
Keep up the god work
"I have been using a NEC MultiSync 97F CRT for a couple years. I see no difference in video clarity/brightness between my Mini, B&W and Sun ULTRA 10 on this monitor.
Tip for ViewSonic P95f+ users:
I have very good and interesting news to update the report I sent you
yesterday. (see below) all this while I forgot about the 3x and 4x brightness
settings on my monitor. its a button they put on some high end CRTs.
normal is for text and such then there is 3x for graphics and 4x for
video. I only ever used normal and 4x but only 4x when watching
anyway.. I set it to 3x and did a calibration and the results were
amazing!!! the screen looks exactly as it should now. i'm so very
happy. native calibration at 3x was too bright but once I did one in
expert mode the end result was awesome. I literally shouted for joy.
a great solution to this issue for anyone with this hardware combo.
the model again is a ViewSonic P95f+B. the B just stands for black..
Jeff's previous report follows:
(added 6/28/2005 - but see his later update above)
"Mac mini 1.25GHz 512MB connected to Viewsonic P95f+B via ati adapter
that came with radeon 7000. (it shouldn't matter if it's a good tight
fit/connection, but I assume he also
tried the supplied Apple adapter.-Mike) I have the dim video issue quite bad.
tried the apple supplied adapter also with same effect. done several
calibrations and it only helps a bit. I saw the report done recently
that mentioned lowering the voltage or something. I can't find this
option in the onscreen controls at all. (that reader report had
a typo on the model number - see his corrected post below. he later
wrote the P95F has only the standard 0.7v setting (which is the
standard setting as far as I know.)-Mike)
monitor is a top of the line 19" trinitron and I have very sad it
works so badly. I am wondering if this
IOgear signal booster/splitter ($69.9x) could add the extra power needed to make my
screen look the way it should.
On my tower with a radeon 7000 32mb
this display looks amazing. please can anyone help me find a way to make this monitor sing on my mini.
thanks, Jeff H.
Since it's also a splitter I wonder if the amp does
much as far as increasing levels over what a non-split output level would
be but you can also ask the vendor/mfr of the device to see what they
say. (I'd explain the mac mini analog video issue you're seeing also)
If any Mini owner that has a monitor that shows the dim analog video
issue tries that splitter/booster, let me know.
"1.42 mini bought at the Apple store with 512MB RAM, Bluetooth,
Airport, modem (location still on a landline), and Superdrive
Hitachi/Raster Ops Mc 7515, 19", 10 years old.
This monitor was originally bought to serve with a PowerPC clone and
then used with the G4 Dual 500 for 5 years.
I am using the DVI > VGA (adapter) provided by Apple. I have had no problems
with my display. The settings I arrived at with the clone needed
readjustment for the dual G4. I haven't gone over them for the mini,
because I do intend to replace it in a couple of months with the 23"
Apple. Then I can get myself out of this corner and hook the CRT up
to my old G4 again. I'm sure that the Apple monitor beside this one
will be clearer and brighter, but that's the nature of the two
monitors. This one is doing quite well for what it is.
The only issue I had was that I attached the monitor to the adapter
before attaching the adapter to the mini. While it seemed ok, it
actually had to be done the other way around to get a snug fitting
and good pic. It's so obvious that I suppose anyone with problems
checked that out right away, as I did.
Input Voltage Settings (0.7v vs 1v) Note:
(added 6/23/2005 - display model no. corrected per his email on 6/24)
"I do NOT have the dim video problem with a ViewSonic E70f+.
(The model number I originally gave is WRONG. (he originally wrote P95f+-Mike) In fact, my ViewSonic is the E70f+, which has two input settings: 0.7v and 1.0v. The more
current E75F also has both settings. The P95f+ only has one setting,
but it is the 0.7v setting that does work with the Mini.)
However, I have noticed something in the monitor hardware settings (not the computer calibration settings). In the ViewSonic's own panel, there is an Input Level setting on the second pane of the monitor parameters. It has two choices: 0.7v and 1.0v. Mine is set at the LOWER value (0.7v). If I set it at the higher (1.0v) level, my screen image becomes MUCH DIMMER. Since this is an INPUT setting, the 0.7v setting is the one used when the incoming video signal is weak and the 1.0v setting is the one to use when the incoming signal is strong.
I do not know if other monitors have a similar setting, but on the ViewSonic, changing it makes a HUGE difference in screen brightness. Anyone with dim analog video should check to see whether the monitor being used has such a setting.
IIRC, 0.7Vpp is standard.
"Interesting to see other reports of video trouble on the MacMini.
I purchased a MacMini with the idea of using a Power Computing (Apple
Clone) CRT. It wouldn't even get a signal. (Assuming the adapter was
firmly connected, I wonder if the mode was out of range (too high
a refresh rate, res. etc.) for the older CRT?-Mike)
The CRT was working fine on a G4 Mac. I ended up buying a Dell flat panel display which works fine
with the Mini's DVI port - but the point of buying the Mini was to avoid
the coast of another monitor.
Apple tech support was no help. They only wanted me to purchase
Applecare - which I already had for the MacMini. I need to call back to
see what if anything they plan to do about the trouble.
Thanks for the site and the user feedback. I happened upon this by
(he later wrote)
I even took hooked up the MacMini to a friends monitor and it worked fine. I
dialed down the Mini's monitor's setting and hooked it back up to the CRT
I ended up getting the Dell 20in widescreen, 'cause I knew that worked.
That's what my friend had - I called AppleCare again and they're not much
help. I wonder when they moved the support offshore? I had a very hard time making
the fellow understand my problem. At least he didn't insist I purchase
AppleCare like the last time I called. I already had AppleCare and the
fellow didn't even want to listen to my problem but kept insisting I get
AppleCare - he didn't seem to hear I already had AppleCare.
I tried to contact the Apple Store here locally to ask about what they've
been told Mac Mini video issues and I couldn't even get through. No one
answered the phone. I called 5 times. Very odd.
Thanks for the site, I've always enjoyed the info you've got and it was
really helpful to see others with a MacMini video problem.
"I got a Mac mini about a month ago (May '05) and am having no trouble
with my VGA monitor. I just plugged in the included VGA adapter and
everything worked fine. I recently bought the monitor used so I don't
know how old it is, it's a Sony Multiscan 400 PS. I hope that helps someone!
Although if you're happy with it that's all that really matters, I asked if he'd compared brightness levels of the monitor when connected to the Mini vs. any other Mac or PC. (Some monitors show the difference more than others, reportedly due to a lower than VESA spec analog voltage level on the Mac Mini analog video per
the original C'T magazine review tests of the Mini.)
"I have experienced "washed out" video on my Dell 19" (trinitron) monitor.
"Mike, Brand new Mac mini (purchased 5/18 from an Apple store). Two different
CRT's - IBM P76 (17", Trinitron tube, manufactured 2000) and Dell 1726T-HS
(17" Trinitron tube, manufactured 1996). Direct cable connections via
Apple's DVI/VGA adapter. (No KVM, no VGA extender cables.) Both are run at
1024x768, 75 Hz.
Both monitors exhibit the "dim video" problem, where whites look like a very
pale shade of gray. (Each display gives much brighter whites and more
brilliant colors when run off an ATI 7500 in my PC. Text is also much
crisper on the PC, but that's another matter. Why Apple insists on blurry
on-screen fonts is beyond me.)
I have no other artifacts in motion videos (no green dots or other things
reported by other folks). I tried an ATI DVI/VGA adapter but got no video
signal at all (I assume a defective adapter, because it also gave me no
signal when used with the ATI card it came with in my PC).
I went through the color calibration process (including the "expert" process
with its extra settings). I also tried the contrast setting under the
Universal Access system preferences panel, but that just tended to wash out
the screen and decrease the visibility of small color differences and
The display quality is not "bad", it just seems dim (and sort of dingy) when
compared to a PC on the same monitor. I probably wouldn't notice if I
didn't have the two screens running next to each other, one on the Mac and
the other on the PC. But I have to agree with the general consensus,
something's not right with the video output of the Mac mini.
One thought has occurred to me - if the problem is the analog output
voltages being too low (as suggested by c't Magazine), (level under the VESA
spec they said-Mike) I wonder if a good
quality VGA video amplifier with variable gain (like one of the units made
by Kramer Electronics) could be used to fix the problem. Just a thought.
Not sure what they cost but I'd be more tempted to look around for
an affordable DVI (digital) LCD display. (Granted that adds more cost
for those that don't already have a DVI display.) Some said monitor
"Yes, I have the dim monitor issue. I am using a KVM switch, but
directly plugging into the mini yields the same results. I am using a
Dell 21" trinitron monitor.
My theory is that the dvi>vga adapter is sucking out luminance. I
haven't had a chance to read all the information on your site, but it's
somewhat reassuring to know I'm not the only one.
regards, Brian P.
Actually lower than spec analog video voltage levels on the mac
mini is believed to be the source. The DVI-VGA adapter is a simple mechanical connector
(just connecting the analog video pins in the
DVI-I connector to a VGA connector) - so unless it has
some connection problems (high resistance connection)
it should not be a factor, although some believed it was.
The C't (german) original review of the Mac mini that noted this as the cause of the problem and they
recommended using digital (DVI) displays with the Mac mini.
(no other review measured the analog video level of the mini
- they tested it after seeing the problem apparently)
"I have the problem of a dim screen. Tried my monitor on another mini and
the same thing, a dim screen. I'm using the DVI to VGA plug and have
cheap LCD monitor (LG Flatron L1510S). This monitor was attached to a G4
350mhz and was crystal clear, bright and perfect for what it is, but now
on the mini its pathetic, OSX looks like crap on it. Not pleased, and
will be telling apple my woes.
All the best, Martyn P.
"I have had a Dim Video problem for nearly a month. I read the 3/18/2005 email, and I can say that unequivocally using a DVI adapter other than Apple's fixes the problem in probably all cases. (Unless the apple adapter had a high resistance/poor connection it should not be the cause. That's not been a fix for everyone unfortunately as the adapter can't increase the analog video level out of the Mini.-Mike) I was able to step up from 1344 x 1008 to all the other resolutions on my 19in Mag 800V where the screen runs just as well and better than a 64 meg GeForce 4200!
Some monitors are more prone to show the problem apparently based on reports. Some also noted
monitor calibration helped, but that was not a fix for everyone.
"Hi Mike, Love the site, I'm running a 1.25 G4 Power Brick umm I mean a Mac mini with 1 gig of PNY 3200. I have to use the (Apple) DVI-VGA adapter and do not have a dim screen or a lack of contrast. I've tested a 15" Mag LCD, 16" Viewsonic A70 ( rather old now but still great), and a 17" Princeton Ultra 72. I have compared the mini to my G4 400 tower and it all looks the same.

"Hello. great site, too much information for me!!!
I have a new mini.
I buy also a Samsung LCD Sync Master 930MP he has DVI, VGA,
the first day I attach my samsung with DVI cable, looks good, very good.
Third day I attach the DVI to video adapter for connect Mini to TV.
The adapter is original Apple.:
when a reboot my mini I don't see any image on my TV and also my LCD
on video input. I disconnect the adapter M9267G/A and back to DVI cable for my LCD.
Blank screen. But one thing is strange:
If I disconncet a DVI cable from mini the monitor sas: check cable, no
If I reconnect the cable is like a standby, power led blinks like if I
went away from mini.
I think there is a signal, but not enough, if I read on your
site. Apple send a second mini I'm waiting for.
many people have big trouble with LCD, but I think that the adapter
broken the digital side of my radeon, because if a connect the DVI to VGA is all ok on LCD.
Can you suggest me something? I'm worried. I'm afraid when come a new mini from apple and I do to recconect to my
LCD. I don't use ever more the DVI to VIDEO adapter for sure.!!!!!
Next week a go to local store for test the bad adapter (DVI to VIDEO).
What do you think?
ciao ciao from Italy
p.s: for me no big difference between DVI and VGA
sorry for very bad english
(he later wrote)
Hello Mike, no problem for late, you are very busy!
With a Apple by phone we try all the reset procedure.
The DVI port is gone. May be an adapter fault.
Apple sent me a second MINI in 2 weeks.
I also bought a new adapter and now my MINI works great on TV
This is the story (in italian)
ciao ciao, andrea
I don't know why using the adapter would have affected anything but if it's not a random hardware failure, I'd try resetting the
NVRAM perhaps. Boot up with Command + Option + O + F keys held down to get to the OF terminal screen
Then enter these commands (enter means press enter key)
The last command will restart the mac.
"Even though I waited 6 weeks for my mac mini, I did get it and the video
is working perfect. I ordered the 1.42Ghz with the superdrive, and have
yet to try a DVD or burning yet. As for the display, I have a Compaq
15" LCD, and I think the model is the 1501 series, and it's just fine.
I think it's maxes out at 1024 x 768, but it is just as clear as it was
on a B&W G3. Thanks.
(Just to verify I asked if the LCD display was a VGA (analog) model.
Not all analog monitors show the problem based on reports (some may have higher gain).
Yes, it is a VGA model. And so far, everything is working fine. I
haven't gone to Tiger yet, but maybe soon.
"I received my Mini a week ago and hooked it up to an ancient, 10 year
old 15 inch Magnavox model CM2099DU01 while I'm researching 17" and 19"
DVI LCD's to use with the Mini. No brightness problems at all with that old Magnavox.
When I read about the dim video problems I also connected the Mini to a
19" Dell Trinitron, model P991 which I use with my G4 AGP with analog
video. Again no problem, the brightness with the Mini is the same as with the
G4 - in fact, on the Dell P991 I just completed a display calibration
following the steps that Apple suggests and the brightness control
ended up right at zero on the monitor.
The display is bright, clear with excellent colours.
Interesting to note that Apple, today, locked the "Mac mini VGA output
very dark..." thread on their mini discussion forum, in the Displays
About the same time they posted this as a sticky post at the top of
It covers the obvious things and then suggests that Display Calibrator
Assistant will help, as though it can do anything other than fiddle w/
color temp, gamma, etc. The DCA does not have a "increase VGA voltage
to VESA levels" option, sadly. At the end of the doc, Apple indicates
that the machine can be brought in for evaluation, but we don't see
any reason to believe that Apple has fixed this problem in current
minis, as they do not acknowledge a dimness problem. Highly
A few Mini/VGA Monitor users said calibration helped and some
mentioned connections not tight, different adapters/Fit, etc. but my feeling is that some monitors are just less sensitive to it. (Higher gain perhaps? - If all Minis have the lower analog video level mentioned by CT Magazine in their Mini review.) See below for reports from some Mini owners with certain VGA displays that said they didn't see the problem (although many have).
(from 3/18/2005 mail)
"Hello, We were reading your article and would like to report that we
too are having Mac mini video problems. We cannot achieve any white on
our screen what so ever. Everything has a tint of gray added to it.
Everything is also blurred. Today we substituted the Apple DVI adapter
with one from ATI, and to our amazement all of the blurriness went
away! The screen is also much brighter, not perfect, but much brighter
none the less. If we find anything else that improves the picture
quality we will let you know. Thanks.
I wonder if there was a fit issue with the stock adapter (since it's just connecting/passing the analog video pins in the DVI-I connector to a VGA connector).
Notes on DVI and Underclocking the Graphics Chip:
(from 3/16/2005 mail)
"This is actually a report on the opposite!
Here in Sweden the most debate on Mac mini graphics on forums are
concentrated at that it won't work on DVI-displays on resolutions
bigger or equal than 1280x1024, without severe artifacts! (Some other Mini owners have noted this also.-Mike) Apples own displays though work well.
I got my Mac mini about a week ago, and notised no differece between
VGA or DVI brightness, but the screen flickered so much on DVI and
above mentioned resolutions that it was impossible to use.
After I had OC'd to 1.5GHz and then 1.58GHz (shows 750MHz in ASP)
I notised that the symptoms somewhat were less, so I could go from
1024x768 up to 1280x1024, with the restrictions, not to move the mouse
too quickly or opening/closing windows too much.
Opening the screensaver settings panel with "flurry" in the panels window was still a disaster, giving so much flicker to force a restart! (worst case)
Trying other options as changing cable or settings in XDisplayConfig
didn't help at all. Actually a better (but longer 15') cable yielded in a black screen!
But another (tip) from a forum here to use ATIaccellerator II (overclocking utility) and lower the frequency gave a 100% total medicine against all symptoms.
If I lowered both the GPU and graphics memory frequency to about -30%,
not only the artifacts and flicker was gone, but the screen got extremely sharper and brighter in its output (both VGA and DVI!) Its such an astonishing clear picture now, that I've never seen anything as good before!
If you use DVI, you still can see some sort of small multicolored glowing spikes on dark portions of a display, as in "flurry", that I think come from that the Mac mini has no frequency buffering L3 cache and the L2 runs at full CPU speed. This maybe lets the spiking that all digital circuitry leaves behind from the short circuits at passages between "1" and "0" levels, into the graphics, directly connected.
This may cause the bad VGA dimness, as it blurres the signal up, both in time and amplitude - so maybe the fix above also works on the VGA-problem?
"Just thought you might like to know, I saw this message on the main thread about this issue at apple support:
All, Well, we may finally be getting somewhere on this. apple support just called me back, and they verified that this is a known problem with SVGA or XGA monitors, but not VGA monitors. It seems that SVGA monitors have some kind of extra sensing pin that does not work properly with the DVI to VGA adapter. I'm no engineer, but it seems to me that a different adapter could solve the problem, but apple support does not have a fix as of right now.
Anyway, sounds like I have the option of returning the mini. I just have to decide to do so now.
I don't see how that is related to what is said to be the issue (low analog video level) although some monitors seem to have higher gain perhaps.

"Mike, When I read the posts on your website about the dim video issues of the Mac mini, I hesitated for one second, but ordered the Mini anyway. I just received it about an hour ago. (Oh my god, it is a thing of pure beauty) I have no video issues at all, it is as bright as my iBook that I used to have hooked up to my screen.
My screen is a Sony Trinitron CPD-E500, which some users have reported problems with. There was already a colorsync profile for my screen in the system, showing the exact same brightness levels as my iBook did before. I usually prefer my screen to be a bit darker so I selected the PC gamma setting. Colors are rich and vivid.

"According to a German website (which I can't recall) (as mentioned here many times - it was the C't magazine review of the mini that had the test results noting lower than VESA spec analog video voltage level-Mike) which reported some testing on this issue, the VGA
signal voltage from the Mac Mini is below standard
spec. This seems plausible and fits my own experience.
As a result you can expect:
- some monitors will never work well, since without
the full inpt signal level they will not be capable of
displaying full brightness on screen
- some monitors will be perfect right away. These are
monitors which include automatic level detection in
their circuitry, and adjust automatically to different
VGA signal levels.
- some monitors will work just fine, but only after
manual adjustment. It is worth checking details
carefully in the instruction manual for the monitor to
find out how to fix this.
I suspect that most monitors will, in fact, work fine
once set up correctly, though many will be dim 'out of
the box'. Simply running throught the calibration
routine may be sifficient in many cases (as some have
In my case, using a Difusion P170 LCD monitor, I
needed to adjust the RGB input levels from their
default 50% to 60% using the monitor's On Screen
Display. This plus calibration fixed the problem
So, my advice is to start by running throught the Mac
calibration procedure from Monitors control panel. If
that fails, dig out the instructions for your monitor
and see if there are settings that will allow you to
manually adjust the VGA input sensitivity.
Good luck. -Eric W.
"I have a 19" Envision 985 connected to my 1.25 Mac Mini, via the
DVI-to-VGA adapter. I have not noticed any degradation or dimness in
picture quality. In fact, the screen performs better on this than it did
on my old Sawtooth's DVI-toVGA cable, from the Apple Store. Everything
is nice and sharp, no distortion or color shifting like my previous setup.
One thing I notice about the DVI adapter, is you have to really push it
in good to be flush with the Mini's backside. I'd wager these folks
having brightness problems aren't making good contact. (that was one
theory someone had here in the past (and notes on apple's forums)
but I also think that some monitors may be more sensitive
to the issue (assuming the lower analog video level is common)-Mike)
Mac Mini 1.25GHz, 256MB ram, 40GB HD,
"Hello again. Love the t-shirt you sent. It's at the top of my drawer so I wear it about once per week. Feels good flying some Mac colors again.
Anyway, you may recall that I submitted all the photos for the iBook ram
expansion and my general impressions of owning a Mac (12" iBook) again, but I am now writing to talk about my new 1.4GHz Mini. Yes, that's two new Macs in less than three months :-) . Granted I am an old school Mac user, but Apple got me back on board with some of its latest offerings after a year away from the platform.
Dim video issue:
I have the Mini sharing a Viewsonic P815 21" 4.5 year old CRT and I am using the vga cable from it with the vga/dvi adapter from Apple. It is securely seated with no fiddling done to it at all. The P815 has dual connections, the other being BNC and it connects to a high end Athlon 64 3400 gaming rig with an ATI 9800xt 256MB video card. The Mini did "appear" to be bit subdued at first, but I ran a color profile setup on it and I'd have to say that now it seems about as equal as I can tell compared to the listed PC's output. It may be a bit dimmer, but its near impossible to tell. Nothing to cause me any worry at all. The Mini recognized the Viewsonic out of the box.
I have no means to test beyond what I see. As a side note, I have this
set-up sitting next to another PC that is connected to an NEC MultiSync
FE991SB (Superbright) Diamondtron 19" CRT that is only about 12 or 18 months old and the Viewsonic is noticeably dimmer even compared to normal bright mode on the NEC. They are side by side monitors. If I kick in Superbright, it's a massive difference. So my Viewsonic is just starting to fade a bit after many years of fantastic service. I have both PCs and the Mini pushing 1280x1024 resolution, highest color settings on both monitors and the Mini thus far handles it just fine...
He had other comments on the Mini added to the Mac Mini feedback page.
"I've plugged a new mac mini 1.42ghz into a 21" Viewsonic with the
adapter and the video is substantially (20 or 30%) dimmer than when it
was hooked up to a G4 tower. It's not really useable.
"Hi Mike, Last week I reported that my 2 Mac Mini's worked fine with the Philips 107 T51 monitor I have and that the image was as bright as the TFT screen of my Powerbook 15". (I asked if he'd compared it to another desktop system - Mac or PC. It could be that his Monitor just doesn't show the problem (assuming the low analog video voltage noted by C'T magazine is common).-Mike)
Yesterday and today I have done some some 'testing'. I hooked up the
display to the Powerbook and calibrated the display 4 times. At the end
I had 4 color profiles which were virtually identical. There was only a
slight variation of the brightness setting of the monitor (1 time value
28, 2 times value 29, and 1 time value 31 on a scale from 0 to 100).
The values itself are not important but they do show that there is
plenty of headroom for the brightness setting. With the brightness set
to 29, I could clearly distinguish all 24 black levels of a test
pattern (going from white to black). White-point was set to 6500K. Also
not important on itself but I wanted to rule out that the screen would
look 'dimmer' to the eye with either the PB or the Mini only because of
different white-point. In my point of view, blueish white looks
brighter than yellowish white.
Now it was time to unhook the VGA display from the Powerbook and try
the Mac Mini without changing anything. I expected to see a (slightly)
darker image, but on first sight this was not the case.
Next step was to make a new color profile. While doing so, I covered
the of the brightness setting so I could not influence myself. I did
this 3 times. The result....2 times a value of 29, 1 time a value of
30, and 1 time a value of 33.
It is too close to call, but I would say the 2 screens are as bright...
Does this mean I am lucky and that my Mini's are not affected by this
'problem' ? Or may I conclude that the VGA output voltage of my PB 15"
is 'also' below 'standard' (whatever that is). (It could be, or your monitor may be one that just works well even with the lower signal level.-Mike)
Many posts refer to an article in a German magazine. I haven't read the
article myself but I know from this magazine that only the best -in
technical terms- is good enough. (they're not saying it has to be the best - just that it was below the VESA standard. And clearly more than a few have noted dim displays or lower contrast, etc. with their particular VGA displays.-Mike) It is about the same as with digital
camera's. When a new version is introduced, the 'old' one, is suddenly
labeled as bad... (I don't think that sort of analogy is at all applicable in this case.-Mike)
My conclusion of this all is that I am still clueless about this
reported Mac Mini VGA problem. (see some of the other owner reports here. But if you're happy with your monitor's image quality, that's all that matters.-Mike)
I remember when I bought an eMac about 3 years ago. It also had a
display problem and my eMac got 3 new analogue boards (which included
the whole display) costing Apple a fortune. Apple kept the whole thing
quite and every-time I called Applecare, they told me they were unaware
of structural problems while the mechanic told me he was swapping eMac
displays whole day....As you probably now, Apple finally found out it
was a cheap cable (IVAR cable) that caused all of these problems.
Digging in to the problem earlier, would have saved Apple a substantial
amount of (wasted) money.
I would be interested in test results of similar tests doe by Mac Mini
users who also have another Mac at hand.
Best regards, Armand
Others have noted comparing the display quality (analog/VGA mode) to other systems (PCs or Macs) and some said they clearly saw a difference. Not everyone did though, which is why I asked for specific monitor brand/model used be noted in reports. Some also reported monitor calibration helped in their posts here.
Note: A reader that works at a dealer said a Mini owner brought in his
system and ADC display (which requires a DVI to ADC adapter for use with the Mini's DVI port) which wasn't showing video. He said replacing the Mini's power adapter solved the problem. He thought that the low analog video (dim/low contrast) issue many reported may be due to
the Mini's power adapter and suggested those with the problem
try swapping an adapter. I said I didn't think that is the
root cause since others reported DVI video was fine (unlike the case he mentioned where the system never output video even on the DVI port), but agreed to mention it here.
I got my mini a week ago (1.42 GHz), and was concerned since I had read
of problems with ViewSonic monitors. I have a ViewSonic E70f. Hooked it
up (what a snap!), and... oh, oh... the monitor was indeed very dim,
and quite fuzzy. Now I wish I could tell you exactly what I did, but
all I know is that I went through the control panel calibration two or
three times, and each time improved the situation. Also, I really
tightened up the connections on the adopter (using the one supplied by
Apple). I am happy to report that now the monitor looks great-- no
fuzziness, and plenty bright enough. The contrast control is set on
brightest, however, and the brightness at about 3/4 of the way up.
Certainly it was much more work to calibrate than I have ever done
before-- but it did work.

they don't support the faqtor line anymore and they are only up to high

Got to say, i am no pro but i didn't notice any dim or diffence in the
image quality compared to my old g4 800 with radeon 8500 on the same
display. Only flaw i noticed is a real hardware problem. The dvi-vga
adapter is, as neat as it looks and feels, a bit of a pain in the ass.
I noticed it tends to bend down when you attatch a vga cable to it (you
know, these things always bend in one or the other direction, so they
pull with some force on the connector, when being screwed to it) and it
doesn't seems like the mini is liking the force being pulled into the
little screws on the back, so i always end up putting a pencil under
the vga vga-dvi adaptor thing to prevent it from being torn appart.
and sorry for the bad english.
"I placed my order three weeks ago and haven't yet received my Mini. However after reading all the posts on static/dark screen issues I started to panic. I didn't know whether to cancel my order or take a chance. I took my monitor to the local Mac Store and they graciously connected my monitor to their display Mac-Mini. It worked perfectly using the original Dell VGA cord and the supplied DVI to VGA adapter.
I didn't change any settings from that used on my Dell 8300. My monitor is a DELL E172FP (VGA only) 17'' flat screen.
The settings used are 1024x768 @ 75Hz. No KVM used in this test. The
monitor is about 8 months old. The display is bright (just as good as the PC) stable and I detected no problems.
It's good to get more reports from those happy with the analog video with their monitors.
I was just reading the apple discussion thread about the dim video problems and one user said that he discovered that his vga adapter wouldn't seat properly in the dvi connector on the mini due to the pins on the dvi side of the adapter not fitting properly. He said he solved this by trimming the pins on the adapter's dvi side resulting in a good connection of the analog vga pins and better video quality.
Perhaps if this is the root of the dark video problem then all that is needed is a slight adjustment to the positioning of the dvi connector on the back of the mini to make it easier to seat the pins on the vga side...
Here is a link to the .
apple forum postings.
I wish this was the root cause, but I'd be surprised if all the adapters used had this problem (some used apple's and other adapters).
However if anyone else notices something similar with their adapter, let me know.

Yes, you are correct. This monitor has a VGA input.
I run it at 1124x768 @ 75 Hz Running it at @ 85 also works, but then the the image start flickering when I activate the 'light-frame' option of this monitor (enhances brightness and/or contrast)
Of course I have calibrated the monitor in OS X and the brightness is
now set at 27 (on a scale from 0 to 100).
Are switchers used to calibrating their monitor?
Some mentioned they had (not all noted it helped) but some monitors may be more prone to the problem (assuming the Ct magazine test results on video level is common).

I didn't try DVI straight from Mini to the monitor (I asked if he meant w/VGA adapter or if the LCD also has a DVI port-Mike), but I didn't think I had to in order to understand what was going on. The 6600GT is hands down far brighter and higher contrast. And knowing the Mini sports an integrated version of the Radeon 9200, I couldn't say I was too surprised by that; however, my girlfriend's computer which I had built for her over a year ago uses a Radeon 9200 SE that is distinctly more contrasted via an analog VGA cable into a Samsung Syncmaster 198n (purchased while she was visiting family in Korea).
I'll try out DVI tonight - though it's unfortunate that VGA folks are out of luck. I'll admit that though the Mini outputs far darker and less saturated than the 6600GT, it's not unusable. I've watched several xvid videos on it - though I do usually keep my room pretty dark when I play video.

"I actually started that thread on the Apple Discussion board. I'm using a 21" Samsung 213T LCD and the difference between DVI and VGA is night and day - DVI is crisp, bright, and clean, and VGA is muddy and gray.
The Samsung is perfectly fine with other VGA sources, including 3 or 4 PCs, and my old Blue and White G3. It's just the Mac Mini that's so gray. I've tried other
displays and DVI-VGA adapters with no joy. I'm more fortunate than many mini owners in that I _have_ a DVI input to use - it's a pain but I can bypass the KVM and switch the source on the monitor, too. Others aren't so fortunate. Bring your own display, keyboard and mouse, indeed - as long as it's DVI!
"Mike - I am having trouble with dim video on a Sony CDP-E400 19 inch
CRT. This was a fairly expensive monitor ($500) and is not exactly low
end equipment. Running video from the Mini through the DVI-VGA adapter
looks awful, regardless of whether it goes through a KVM switch or is
hooked up directly to the monitor. Whites look gray, colors are
severely washed out. Edges, especially on typographic characters are
not sharp. It is especially noticable when switching back and forth
between a Windows PC and the Mini. It would be impossible to use this
device for anything important like Photoshop or even viewing DVD's.
I borrowed a Dell 1704 LCD monitor and tried hooking it up both via
the DVI connection and via the DVI-VGA adapter. In both cases, the
video looks much better than on the glass monitor, but still not as
good as the PC output. I also took it into an Apple store and tried it
with one of their monitors (LCD), of course it looked good on their
This would have been my first Mac. The mac's are touted as being great
for design work and photo manipulation, etc. All the "artistic" stuff.
Unfortunately, the Mini is unsuitable for this purpose. I can't
believe that during the development and QA process at Apple that they
never tested it with any third party monitors. Steve Jobs said this
device would work with any industry standard monitor. The Mini was
targeted at switchers. What did they expect? I'm going to try to
return my Mini tomorrow to an Apple store. Wish me luck.

strain. The dimness is not drastic but noticeable as
soon as it was booted up.
I can't test further since the Mini was given as a
gift and I don't have access to it now.
Hope this helps.
Thanks, Tim H.
"I just thought I would let your readers know that there is also a problem with the NTSC Composite/S-Video output of the Mac mini when using the DVI to the Video Out adapter. Black lines appear near the bottom of the video image in every other frame. This is the same problem that still exists with the PowerBook's Composite/S-Video output.
Depending on the overscan of the monitor/projector you are using you may or may not see it but it is there. To see the problem, record analog video from this output to a DV camera and then bring this footage into Final Cut. You can also see it without recording if you have a professional monitor which has an underscan mode.
I have details on this problem at http://internet.cybermesa.com/~hamilton/PB/ when I FIRST reported this to Apple in April 2001 almost 4 years ago. I guess not enough people have complained to Apple for them to consider fixing it. ATI has software which fixes the problem on their retail Mac Radeon cards but the Mac mini is currently an "Unknown" card. (Mac2TV controls of ATI Display software support retail cards, but not OEM versions)
I would welcome any suggestions concerning how we might get this issue addressed and FIXED by Apple.
"No problems with video on my side. I have two Mac mini's...one connected to a 19" Sony CRT and the other to a Samsung 713v VGA only LCD.
Both look good. Haven't hooked the mini to a 15" Samsung 152T LCD (DVI and VGA capable)
The mini replaced a G4 tower on the sony CRT ...equal quality
The 2nd mini replaced a CUBE and again equal quality...
All's good here...fingers are crossed now...
Some Mini owners asked for specific display model numbers
(from those not reporting any dim/low-contrast analog video) so
I asked Dixon for the Sony model number.
I have the 1.42 mini connected to an NEC 17" flat panel display using a VGA connection. Looks beautiful. No signs of blurriness or dimness. I havenŐt connected the mini to a CRT, however.
I asked if he had compared another system using that monitor. (and as a FYI for others - please include display model number. thanks)
"Mike - Great site. Just got my mac mini. Using it with a 19" IIyama TSA4634JT Monitor at 1280x1024. Looks terrible. Dark, I'd say about 50% darker than the PCs that are using it (through a Corega 4-port KVM switch).
Disappointed as this is one of the first Macs at my work and I was
looking forward to showing it off.
"Hi, this isn't exactly the same problem, but I imagine
it is related ... using the dvi to video connector to
my hd ready tv (samsung 32") with the option of
s-video or component video for inputs, leaves the
desktop unreadable due to bluriness.
Strangely (at least to me) itunes visualizer, marble blast (played
while on hold with apple tech support) & dvds look
great ... just fonts, buttons, menus, etc. are
Apple passed me upto second level tech support who could do nothing & a week ago was supposed to get back to me after consulting with
an engineer level tech support ...
if anyone else is experiencing this issue, or if i am just missing
something obvious, i would appreciate some feedback
... thanks !

Text (esp. small text) isn't great on any Computer->TV connection
in general but the (reportedly) lower voltage analog video
wouldn't help matters. If any readers have a TV with DVI input
I'd like to hear what you think as far as image quality.
"Hey there. Just thought I'd mention that I picked up a Mac Mini over
the weekend and hooked it up to my 50" HD plasma via the VGA connector.
I haven't noticed any brightness or blur issues at all. From what I've
seen from reports so far, it appears that many folks are trying to hook
into standard monitors rather than to a plasma so that may be a factor.
Also, I'm using the DVI->VGA converter that came with my powerbook instead of the one in the MacMini box. Again, don't know if this is a factor or not but given that I hadn't seen it mentioned before, I figured it might be at least a small data point.
Normally (unless there's some high resistance connection) the
adapter wouldn't matter since all it does is connect the analog
video pins in the DVI-I connector to a VGA connector on the other
end. (If you suspect that's an issue - try swapping it and see
if you notice any difference.)
i can confirm that the mac mini's vga (analog) signal is much dimmer than using dvi.
when connected to a samsung 172x lcd display using the vga
adapter, the picture is dim and somewhat blurry. if i connect it using
dvi, the image is bright and sharp. on my pc connected to the same
display, the picture is largely identical between vga and dvi.
"Yep, it's a problem. We did a test this weekend on several different
Apple 20" cinema display DVI connection, great picture
Dell 19" LCD w/VGA and DVI inputs, MacMini VGA blurry and dim,
MacMini DVI perfect
ACER 19" LCD VGA only, MacMini Blurry and dim, Dell running XP perfect
Based on our comparison with the Dell 19" that had both types of inputs,
there's something not quite right about the VGA converter on the MacMini.
"Yes image seem dimmer than IBM vga card output & blurry. On 90hz interference noise can be seen also.
The MacMini output is not as crisp.
Monitor Used, 20" Mitsubishi DiamondPro 2040u and 19" Diamond Plus 91.
So this is definitely true. I'm an EE and have eye for these things. Quality is my main choice.
Let me know how I can help. I've also added a very simple non intrusive HDD activity light to my mac mini that shines right throught the top transparent white plastic.
"One suggestion would be to try a different DVI to VGA adaptor. Have
seen this problem with a powerbook swapped the adaptor and alls fine
Some noted trying several adapters (they are simply
a hard-wired connector tying the analog pins in the
DVI-I connector to a VGA connector. Unless there's some

"Hiya. I have a stock 1.25ghz, using the dvi to vga adapter with my mag
LCD (It only has analog vga input, its a few years old).
Video looks great, as good as it ever did with my pc. I think an issue
can be the colorsync profile, which seemed to be off on my monitor, and
I had to make a few hacks to get things working properly.
One other owner said recalibrating the monitor in OS X helped.
"Greetings, I've been following the threads about dim video with the Mac mini. I received mine last week and have been unable to get satisfactory results with any combination of DVI/VGA dongle and CRT monitor.
I have 3 different dongles from various video cards and 3 different monitors. All work perfectly with any of my 7 PCs and my old beige G3 with on-board video.
The mini video is dim with a soft focus or lack of contrast. Whites
are actually gray and colors are washed out. Same monitor settings
result in vivid, razor sharp video and bright colors when used with
any of my other machines. My main monitor is a Samsung 997DF 19"
CRT, but I've also tried Viewsonic PF790 19" and Viewsonic GS771 17"
CRTs with the same result.
I've read that the mini is fine when used with an LCD display
connected through DVI, but I wouldn't have purchased a mini knowing
I'd have to buy a new LCD as well. In fact, how does one know if an
LCD would actually work better? Is there a list of known compatible
I've tried various resolutions and refresh rates and find that
1280x1024 at 75Hz is the brightest with my mini. Please let me know
I'll be contacting Apple as well to see what info they have to offer.
"No issues - the 1.42 mini is driving my compaq MV940 display better
than windows ever did. At 1600x1200, 60 Hz the display is bright and
text looks great.
(I asked to verify it was an Analog monitor-Mike)
Yes, it's a standard VGA monitor using the adapter that came with the
mini. I picked it up the day that it was released. The latest iLife was not installed (had an extra CD), so I suspect it was a fairly early build.
I tend to keep my monitor brightness at around 40% and did not change
it when going from PC to mini.
"I've used the Mac Mini with a Sony 15" analog display. No dimming problem. Text and colors were better than my 15" TiBook.
"the C't (magazine) in Germany tested the video-output, and it was below 530 mV.
They wrote in the article, that the video would be blurry on many (analog) monitors. They wrote, that a digital monitor has to be preffered. It is in the C't 4 / 2005, side 70.
"I'm using Mini with 17" CRT VGA display with adapter and no problems at
all. Picture quality is OK.

"My Mac mini (1.42 GHz attached to a 17" CRT) arrived on Feb., 9th.
The video output is really not that crisp as You would usually expect.
It clearly has less contrast than all my other Macs and those PCs we
use at work.
On the other side, the video quality is no further affected by the KVM
switch I use.
A rather sub-optimal workaround might be to play around with the gamma
settings a little, in order to get some more contrast.

"I have the same problem.... Very dim video... just thought it was
because I was using a VGA monitor. Should it be bright as my PC?
Normally there shouldn't be any big difference. (I tried to reply to
Brad's mail about this but got a bounceback.)
Our Mac Mini had no such problems when we used a VGA monitor. Now we are
using a Sony 19" DVI LCD. (It's beautiful!)
(I asked if he'd compared the same VGA monitor with another system (that's where some noted the difference). In case there is some change
I've asked those that didn't see a problem if their Mini was an early build.-Mike)
My mini was delivered one or two days earlier than expected from the
original first batches (I ordered the day they were anounced).
I moved the monitor from one mac to this one. This is a 1.42GHz model. I
admit that I could have been unobservant, but that is rare for me. I can
move it back to a CRT and test it out.
"I just spent the last five+ hours setting up a Mac mini (set up, loading software, moving files, virus scan on the ENTIRE drive which took forever, etc.) which is using an old Apple 20" CRT...
So, DVI from Mac mini > Apple provided DVI>VGA adapter > old Apple VGA>Apple 15pin adapter!
Running @ max. rez/max. refresh allowed by standard Mac mini hardware/drivers, which is 1280x1024@75Hz. Or was that 85Hz?
Anyway, no flicker (which happened on the 7500 it was attached to), no dimming, no fuzziness.
HDD aside, the Mac mini (1.42GHz/512MB/SD) is pretty sweet for what it is!
I asked if he had compared the same monitor using another
(more modern) Mac or PC.
I tried my mini with a Dell 15" flat panel's VGA input and the video
was in fact dim. This was probably because I didn't mess with the
color profiles on the mini; I had very little dimness once I tweaked it
for my aged Viewsonic PS790-2.
"Mine seems fine. I'm using it with a 17in B&W studio display
(I asked if he compared the display using another system)
I've used the display with a TiPowerbook as well as a B&W G3, and a
couple PCs, and it's always bee fine. I'll try the mini with another
CRT this week and let you know how that goes.
"I have used my Mac Mini on a Silicon Graphics badged Sony GDM-4011P
20" Trinitron monitor. The image was bright and crisp. I used a medium
duty VGA cable I bought for $19 (not a $8 thin cable, nor a $40
firehose thick cable).

it did not arrive with iLife 05 preinstalled (came on an included
My monitor was pretty high end for its time. I'll try the Mini on
another CRT later this week.
(he later wrote)
Update: I tried the Mini on an AppleVision 750 monitor (old beige 17"
Trinitron) and the colors do indeed look washed out... it looks as
though I was using a long, cheap video cable when in fact I am just
using the 6 foot cable attached to the monitor (plus a VGA adapter
plus the DVI adapter).
It looks like the only true solution is to use a real DVI monitor with
the Mini. Either that or use a very high quality CRT, like the Silicon
Graphics / Sony monitor I had been using earlier.

"Samsung 712N, Mac Mini, VGA. Blurry text. I've done much fiddling with
the Appearance settings, refresh rate 60 or 75 Hz etc. It just doesn't
look as good as the output from my Dell 4600 with NVidia Geforce MX
5200. Same cables. No KVM.
Hope we can get some resolution (no pun) on this matter. I'd sure hate
to have to buy a DVI screen or go back to using Windows XP.
Thanks, R. Falconer
(I asked if he connected that monitor to another
system is there any difference in brightness?-Mike)
I can't really see much difference in overall brightness. However some
of the smaller, grey fonts which are easy to read on the Dell become so
dim that they are difficult to read..
"I wouldn't use the word dim. I would say it is lack of contrast. I am
able to fix it by using the built in cal function in OS X. (Screen is
a pro grade Sony 21" CRT)
(I asked if he compared the monitor's brightness when connected to another system-Mike)
I don't recall any problem with other Macs that had been connected to
this monitor (3 years old). (I meant was the display brighter/crisper with other systems vs the Mini's analog video-Mike) I always work in a very dim room. That may
be why I don't see its dim.
Yes it's true. The german computer magazin CT which is probably one of the most professional PC Magazines out there tested the mac mini's VGA output and noted that it was quite bad. They said you should use DVI instead. Unfortunately their test isn't online; you have to buy the magazine.

"I see it on the main page. But it says to email if there are problems... (to clarify I wanted reports if you've seen it or not with a *VGA* (analog) display.-Mike) I have had none. I have had it hooked to a 19 inch Princeton LCD (via DVI) and have for a while had it connected to an older (5+ years) 19 inch CTX monitor (VGA only). Absolutely no problems with dim video. Just putting in my 2
cents. Oh....my girlfriend bought the mini the first day it went on sale at Tyson's Apple store.
(he later wrote)
I will have to hook up another computer at the same location....no big
deal...I will comment after I have done it. But it is safe to say that even if it is dimmer....it is not a deal breaker for me. The display was awesome on the 19 inch LCD. The older 19 inch CRT is dimmer (but I figured that was just it's age). After I hook up another computer I will post my findings.
If possible - when using VGA (analog) displays - compare the Mini connected to the display to another Mac (or PC) connected to the same display.
"I noticed this with my Mini into the VGA in on my Samsung HLN 567
television. (Port known to work with other machines.) When I plugged the
same mini into the VGA on a multisync monitor I had (old Sun 17", dunno
model number) picture was normal.
Mini is now working fine through the DVI input of the Samsung. I'd believe that the signal is somewhat out of spec and some monitors can't handle it well.
"Yes, I have had this issue with my mini.
I was using a Viewsonic P815 and even with the brightness and contrast at max, the image was dim. This monitor was taken from a PC (Radeon 9000) where the controls only had to be set at mid level to get a bright picture. I also noticed that the on-screen menus were very bright, but the background mini video was dim when both were displayed.
As mentioned on a post at Macminiforums.com, this is only seems to be a
problem with the analog output, the DVI connection is OK. I recently bought a Princeton LCD 19D, 19inch LCD with a DVI connection and connected to the mini through DVI port the picture was so bright that I had to set the contrast to 50 and the brightness 15, both out of a max of 100.
No KVM switch, direct connection in both cases. I even have a high quality VGA to 5 BNC cable that is used with the Viewsonic. Also the Viewsonic needed to be toned down quite a bit when it went back to PC duty. Thanks for the great site!!
"Yes I have the same problem
KVM switch or no KVM switch I use both and YES the screen is very Dim
what do we do?
Don't know what to suggest for end users other than to try a DVI monitor if possible. (Unless Apple comes up with a rework/fix.)
"I am using a 19" newish Dell VGA CRT. I have a new IOGEAR 2-way KVM
that I am using it on, w/ my work PC. I immediately noticed the
dimness - instantly, because when you switch back and forth with the
KVM, it's easy to spot. The KVM is one of those all-in-one units with
integrated cables. I swapped the cables - connecting them to the other
unit and no difference resulted - still dim only on Mac. I hooked the
Mac directly to the CRT and it still looks dim. I then hooked the
mini and the PC to my Sony 19" CRT's dual inputs and switched between
them with the front-mounted switch and the mini is still dim.
Check this post from the Apple discussion from a few hrs ago:
"I bought 4 Minis for our small ad business, to drive 4 Sony 200ES CRT
monitors that still display beautifully with our old Macs. The video
is uniformly dim with all workstations... in fact, the dimness makes
our eyes hurt. Cranking up the brightness just washes out the screen,
as the contrast is already maxed out. This is the first time I've
actually seen OSX display badly, like a generic windows box with $75
monitor you'd buy from one of those traveling expos. What's the
consensus? Is Apple going to do anything? Any suggestions?"
...something is not right. I definitely think Apple needs to
acknowledge this and address the issue. Unfortunately it will almost
certainly involve a motherboard swap which will be hard for Apple.
I am not sure if all units have this issue or not. It seems that
using a DVI screen is better - but that there is still dimness there.
Most pronounced on VGA CRT's tho, it seems. I sadly don't use my mini
for Photoshop work because the colors look so much darker. ...and PS
crashes my XP box 1 out of the launches... Seems an unacceptable
situation with the mini.
I welcome other feedback on the Mac Mini.
