M1 Mac Mini still doesn't wake external monitor

I've got a 2021 Mac Mini attached to an LG HDR 4K 27" display, connected via Thunderbolt. I leave it on and running, and when I tap the keyboard and/or mouse to wake it, most of the time it works fine.

However, every few days (too often to make this not annoying) it refuses to wake the display. I have to unplug the Thunderbolt cable then plug it back in before it will wake the display. The Mac itself is NOT frozen or having any other problems.

The keyboard/mouse is Logitech Ergo K860 and M525 -- the transponder is plugged into the back of the LG display.

I was hoping this would be resolved with Monterey, but it hasn't been (I am on 12.0.1 and still having the problem).

Yes, I have indeed reset the PRAM/NVRAM, etc.
