GTX970
Relevant Specs: Z390 Aorus Ultra & 9900K with OpenCore.

I have a running Big Sur OS that seems to working fine apart from recovering from display sleep.
If I set my display to sleep after x minutes it will stay black even after:
1. clicking on keyboard, mouse
2. Changing resolution via remote control.

I remember having a similar problem in the past when I tried to recover the machine from deep sleep but here it's only the display (everything "sleep wise" is disabled via settings and fans etc' continue to work while display sleeps)

Is there an easy fix for this?

I had same problem and have it fixed by adding igfxonln=1 in the boot-args. You can try it!
