HD4000 problem with alternation of rows colors

[AGluk]

Hello everybody.


Could someone help me with the following question please?


On my Mac mini 6.2 I can't see alternation of rows colours in any application.
It can be seen only in the shadow of another application (see attachment for more details).


My configuration is the following:


Gigabyte GA-Z77N-WIFI (BIOS F2)
Intel i5-3570K
16GB of Memory (32MB is fixed for HD4000 in BIOS).


I'm using PJALM DSDT patches for my board with changed ig-platform-id to 01620005.
I tried several ig-platform-ids without any success in terms of my problem.


Video, HDMI audio, 3D acceleration work fine. The only problem is in alternation of colours.


Please help me. Thank you.

It shows up fine on my monitor in the attached file. So it's rendering correctly, just not displaying correctly. I would try using the Color Sync adjustment to calibrate the monitor (change the gamma). Does the monitor work correctly in other OS's or on other computers, or do you know?

Hi saintmac.


Thank you very much!
You are right. The problem was in my monitor setting: HDMI RGB PC Range.
It was set by default to RGB(16~235). After changing it to RGB(0~255) I can see all alternation lines.
Thank you one more time!
