Nov 3, 2012 8:37 PM in response to den.thedby koyeung,thanks for your monitor setting info
unfortunately, mine (IPS237L) doesn't have "preset sRGB"; setting CUSTOM color with (red, blue, green) all 100% (up from 50%) make no different.

Nov 4, 2012 9:29 AM in response to koyeungby rottenskin,The display issue you're having is exactly as same as mine.
Samsung bx2431 led display and it fails to properly show the light density color,
or the color with low opacity setting on the white background.
Colorsync utility is not helping me at all.

Nov 4, 2012 10:04 AM in response to rottenskinby soundx,I also have this issue.. via HDMI connection to a Samsung TV.
If I change my connection to a MiniDisplayPort to VGA adaptor, I can see the light colors, although faint.
It seems that if I connect through HDMI, the display color profile is set to "HD 709-A".
When connected through the VGA connection, I get the "SMT24A350" profile (which I presume is retrieved based on my monitor type) and the colors look better too. I'm not sure what the best solution is.

Compare these two and see if your issue is similar to the one I have.

Nov 4, 2012 10:15 AM in response to rottenskinby soundx,I'm not sure if I'm looking for the right thing, but I can barely see the yellow triangle in the background. But when I put in my VGA connection, I realized that there were even words inside that triangle!!!!

Nov 4, 2012 10:21 AM in response to soundxby rottenskin,You got it.
That''s exactly the screen problem I have here with my LED monitor.
This HDMI output on Mac mini seems to have a serious problem.

Nov 4, 2012 3:23 PM in response to koyeungby Philip Tyler,Its fine here for me using an Eizo CG223W monitor connected by HDMI to DVI adapter. I also have another monitor connected via Mini Display Port to DVI and that is OK.
I have had the HDMI output go into the static / shash once which went on until I cycled the Eizo through its inputs and when I got back to the mac mini all was OK again?
The other problem I have is although I can calibrate the Eizo monitor and get a good result. My other monitor, a Formac Raven, is coming out too red. So something for me to look into there.

Nov 4, 2012 4:17 PM in response to soundxby koyeung,I have the issue using HDMI cable or mini-display-HDMI adapter. May the problem related to HDMI?
(i've no mini-display to vga adapter...can't verify the vga connection)

Nov 4, 2012 4:41 PM in response to koyeungby rottenskin,Yeah, it's definitely HDMI thing.
Thunderbolt with thunderbolt display is supposed to be approved by Apple, so that can't be a problem.
I'm going to return Mac mini this week, since you guys agree on this low quality display issue,
and thinking of buying Macbook Air, the cheapest one, after I get the refund...
Hope it's the one without any trouble...

Nov 4, 2012 11:33 PM in response to rottenskinby soundx,I don't think it is an issue of the display, rather it is the color profile that gets processed for HDMI output. A software fix would likely resolve this problem.
Though, I wonder if this issue is related to this:

Nov 5, 2012 2:51 AM in response to soundxby koyeung,Looks it is similar: HD4000 + HDMI and some said mini-displayport to VGA/DVI solve the problem.
Unfortunately, that thread started from July. If Apple thinks that is an issue, they should fix it before making more products with HD4000 + HDMI.
We should all give feedback to Apple:

Nov 5, 2012 5:05 AM in response to koyeungby koyeung,Would it be something can't be fixed by Apple?
"HD4000 hdmi Black level not black enough. Gradient Banding too"

Nov 6, 2012 5:34 AM in response to koyeungby gubble,Hi all,
Have you tried windows on your Macs? That is a proof that it is not a hardware issue but driver problem.
Cheers

Nov 6, 2012 3:23 PM in response to koyeungby koyeung,Does anyone try connecting HDMI monitor in this way?
mac mini -> hdmi_to_dvi adapter -> dvi_to_hdmi adapter -> hdmi cable -> monitor
would it fix the issue?

Nov 7, 2012 3:50 AM in response to koyeungby koyeung,tried...no improvement
