I suspect it is a software problem, not a hardware problem. The reason 
is I have been seeing the same for almost a year now with my display. I 
can't find anything that indicates a hardware problem and after all this 
time the display/monitor is still trucking on without the problem 
getting any worse.

I am not 100% sure, but it seems like sometimes the display is put into 
sleep mode and can't be woken up. Restarting X or doing a modprobe from 
a remote machine over ssh doesn't help. Nor does anything else. The only 
way to get the monitor to activate again is to reboot. After some 
digging I gave up on finding the root cause and accepted that I'd have 
to reboot once in a while. There is nothing in the logs to give any 
indication of a possible cause. Maybe I should have tried harder, but I 
just don't have the time for that at the moment.

FYI, this is the relevant hardware in my system:

MoBo = ASUS PRO WS X570-ACE
CPU = AMD Ryzen 9 3950X
Graphics = ASUS AREZ-RX560-4G-EVO

Debian version is Bullseye following testing very closely.

Sorry I can't help you with this.
