Hi all, Not sure if this is a distro specific, DE specific, a monitor brand specific or just linux/AMD in general. So, I have an RX580 GPU. It is an older one, but does just for what I do on my PC (emulation). Everything works fine until I start one of the emulators and play a game. I have two 27" 4k monitors, a dell and a sceptre. Once the game starts, the sceptre monitor starts going black every couple of seconds, then comes back up. This continues until I stop the game. Both monitors are connected through DP to the GPU. Not sure what to do, to be honest. All drivers are there when I checked (as far as I know). This happens on both wayland and xorg. Any input is greatly appreciated! If anyone needs more info, please let me know. Thank you

System is:

  • Same GPU, same problem. What fixed it for me was to use the monitor’s settings to lower the DisplayPort version, but this was on a Dell monitor, so not sure if it’s possible for you on the affected monitor. It might also be worth swapping cables and seeing if the Dell has the same problem.

    • This kinda makes sense. But the dell monitor is where the games run, and is fine. The affected monitor is a Sceptre. The issue seems to have gotten a ton better when I switched the Sceptre to HDMI instead of DP. I’ll look into lowering the dp version on the Dell monitor and see if it’s even an option on that monitor. I like to play on the dell because the picture on it is a lot better than the sceptre
