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

One thing that could be worth checking out is whether the power supply is bad/insufficient. That could explain the GPU working when just using the desktop normally (GPU idle/low power), but when launching a game the GPU might get insufficient voltage or something causing the output to be unreliable.
Or as others have mentioned as well, maybe it's a bad display cable. To try to find the cause of the issue, perhaps try to swap the cables between the two monitors to see if the monitor having issues changes. If there is no change, try to swap the outputs used for the monitor to see if the GPU output is bad (if swapping the output causes the other monitor to have issues instead).
When the screen goes black, does the monitor complain about missing input, or is the image just black as if the GPU outputs a black image? If it is missing input, then maybe the cable/output is having issues. If the image is black then it may be the GPU having issues.
Power supply is literally 2 weeks old. It's 750 watts, so plenty of power there. I used an HDMI instead of the display port and the issue is now almost non existent. I'll try to find another dp cable and try it. I haven't
heryet swapped the cables (good idea). And the screen just goes black, no messages from the system
