When my display comes back from sleep, it shows a lower resolution with black sidebars. If I turn the monitor off and on, it comes back with the correct resolution 1920x1200. I am not sure what is causing this, the AMD driver or Windows 10 Pro.
I have the latest AMD drivers installed on my 5700XT and I am running Windows 10 version 20H2 build 19042.844.
