I’m 100% sure it’s not a cable issue for many different valid reasons one of the main ones being that the cable is able to drive higher res monitor at higher refresh rate without issue.
Also if I just swap cables from my main monitor with the 2nd the same issue still happens with the 2nd monitor but only in Linux, never Windows.
Thanks!
1.) will definitely give it a try 3.) I have set the amdgpu feature mask otherwise I wouldn’t even have access to the power limit, voltages, etc… but VRAM overclocking just does not work. Everything else seems to work fine.
