April 4, 20233 yr I am using 3 monitors connected to my GTX 1060 GPU and in all VM's I have tried the monitors works correctly. But only in my Windows 11 VM I have the problem that one of my monitors change the colorformat from RGB to YCbCr422 8-bit SDR which looks really bad. I have tried creating new windows 11 templates and sometimes all monitors use the correct colorformat. But after a little while when I have ulocked the vm it is back to YCbCr422 8-bit again. If I use the nvidia controlpanel and change the colorformat the monitor just blacks out then reverts again. I am using a dock for my work computer connected to the same monitors and that one uses the same cables and also works fine. Does anyone have any idea of what can cause this ?
April 8, 20233 yr Hi, Viewsonic monitor or what brand? How is it connected? hdmi, dp? What happens if you powercycle the monitor?
April 11, 20233 yr Author Nothing happens when I powercycle. I am using 3x AOC 1440p monitors, and they work fine when I connect the same cables using my work computer or when I start an ubuntu VM.
