Well, I've replaced my PG32UCDM for PG32UCDMR.
It's ok, but there are couple of issues.
1. Brightness is not adjustable via Display Widget Center if 'uniform brightness' setting is enabled. It's clearly a mistake because you can still adjust brightness in monitor menu and you can adjust brightness in DWC when 'uniform brightness' is disabled.
2. (Solved) Horizontal white lines under certain conditions in SDR. Easiest way to recreate is to run Black Myth Wukong shader compilation or loading screen. Screen flickers and white lines are flashing. I've also spotted a white line in Sword of the Sea when it was for 1920x1080 (default).
However after some hours of use, switching DSC on and off, switching DP to 1.4. and back to 2.1. and updating nvidia drivers to 581.94 I can't recreate those lines anymore. *So it looks like NO problem here*.
A little update. At Settings > System > Display > Advanced display Windows shows NO TB400 certification, but it showed one for PG32UCDM, looks like ASUS need to publish a certificate for PG32UCDMR.
I hope for some reaction here.
