i had an issue with an older Firmware, where only HDMI 2.0 worked, HDMI 2.1 went the screen black and no signal. Now i am using DP
huh yeah i just tried with DP and it's working this way for me too (no black screen with DP). strange that hdmi 2.1 was working for me until i updated my version of windows 11...
but at least DP works - guess i'll stick to this and switch one of my other monitors to hdmi
