Mac Mini M1 DisplayPort issue

I've written about this before and some people told me not to make my display sleep but this just doesn't seem like a viable solution to me.

The problem:

When my Mac Mini M1 is connected to my 5k Samsung 49" display, it works great...however after the display sleeps (from Energy Saver turning off display after 15 minutes), it doesn't seem to wake-up the display when I press on the keyboard or move my mouse.

If I unplug the Thunderbolt connector/DisplayPort from the Mac Mini then plug it back in...it works fine.

Does anyone else have this problem ?

My M1 mini running 11.1 is connected to an LG 32 inch display via HDMI, not USB-C, and a single press on the Apple Magic keyboard or single click on the Magic Mouse 2 wakes up the display from the screen saver.

FWIW, I have a similar issue waking the display with an M1 MacBook Air without an external display. For some reason the screen back light doesn't come on. The workaround I use is, setting a Hot Corner to start a screen saver (I use Drift), mouse to that corner, then mouse away or press a key.

I guess the only solution right now is to run the screen saver. I was hoping to use the energy saver and make the display go to sleep (and wake when I shake the mouse...like on my Mac Pro...I guess I'll have to wait for more updates)
