Had the same problem with my CG437K but turning on HDR in display setting works. Do you have multiple display? I have to set show only on 1 (CG437K) to get it to work but then it kills the HDMI audio output to my receiver. Changing to Extend these displays works.
Yes, only one screen
You using DP or HDMI? Maybe try a different cable (I know long shot). Also are you using nVidia color setting under change resolution in the nVidia control panel?
I am using a DP which has never given any problem and no, i am not using that setting.....should i?
Might as well give it a try, 32bit, RGB, 8 or 10 bit and see
Tried that, didnt work
Damn, I'm out of idea. Maybe post over to Steam discussion or discord and see if anyone else have the same problem and solution.
I'm pretty convinced that's it something in display settings as I just got back to the office today and I got the it running under HDR even on the 4K TV that's I'm using, Play with display select and and maybe nVidia control panel and just try everything.
