Black Screen Issue with Windows Power Settings

Nadder

So I've been experiencing this weird issue that whenever my monitors turn off (doesn't happen when I change it to never turn off in Power Settings) the display drivers crash. My GPU is the RX 6600 XT. I RMA'd the card before and the manufacturer said it wasn't the issue so I'm at a loss to what could be causing the problems.

You can try the ULPS fix (Ultra low power state), its been known to cause wake from sleep issues on AMD cards.

Windows + R or search and type 'regedit'. The setting is hard to find, as it's under HLKM\System\CurrentControlSet\Control\Class but you have to find the GUID string for the GPU. Easier to hit F3 and search for 'EnableULPS'. Double click on the entry, it'll be a 1, change it to a 0 and hit "Ok" and then reboot. Only change 'EnableULPS', don't change 'EnableULPSNA'.

Greetings. Please try a clean install of your video card drivers, here is a step by step guide on how to do this (the steps are the exact same if you are using Windows 11): https://community.microcenter.com/kb/articles/133-how-to-clean-install-video-card-drivers-in-windows-10
