Often, when EOS goes into Standby, resolution after wakeup ist fixed to 640x480.
Even a reboot does NOT fix this. The monitor changed to unknown.
Only fix is unplugging the DP cable and plugging it in again. (Same DP port.) The monitor is also recognized as DELL again.

I am running Wayland with KDE on a single monitor setup, but even starting a X11 session after reboot does not fix the problem.
Sadly I can’t reproduce it right know with enforced standby. But it happens nearly daily.
Does anyone have an idea, what could be the reason?
Also let me know, if you need additional logs.
