light colors are gone for Mac Mini (late 2012)

Light colors are shown only under the other window's shadow area. (see the alternative row of blue color under TextEdit's shadow). Adjust the display from its OSD / tune using ColorSync doesn't help. (enhance contrast is set to "normal"; PRAM has been reset)


Do you have similar issue?

What a crap, i have the exact same thing. The background of my website isnt even visible.. I want to connect with hdmi because i have another pc connected to the screen already with DVI. This is really disapointing 😟


I will try the DVI setup to check if there is any difference. Otherwise i would have to return this thing because this way its useless.

I am dealing with this issue since three months now. have to use the VGA port with an MDP (Thunderbolt) to VGA adapter. That gives me the best picture result.

Brought the machine back to apple and they confirmed that this is really an "issue".

Waiting now since ages for an update or a fix, but nothing happens.

Apple just wants to wait-out the problem

I guess it's good that I'm not alone? I've go this issue too. Just purchased, two days old straight out of the box, wonky HDMI. My old Mac Mini was no problem. This one 2012 is verified that the HDMI output is the issue. [4 different monitors, 4 different HDMI cables]. The thunderbolt port is doing fine. I can tweak the contrast and whatnot to make it tolerable to use, but impossible to use for color work in any way.

I just installed the release version of OS X 10.8.3 on our 2012 Mac mini, and colors appear to be back to normal. I did a fresh calibration. Looks great.

🙂

We were having a new problem where the display (Dell 1080p via HDMI) would very rarely go green/violet until I re-plugged the HDMI cable. Seemed different than the blanking problem recently solved with the EFI update. Hopefully, this stops that as well.
