Update: while in Gears 5 today, I went to game menu while playing multiplayer, and out of no where screen went black for 10 approx seconds, I then pressed on the monitor the power button and screen came back. Monitor G5/32".
Enhanced Sync was ON, and I am on 21.7.2. now, maybe I had the enhanced sync black screen bug? or the black screen bug in Enhanced Sync is different one?
Radeon 6700 XT Eagle by Gigabyte
Thanks!
BIG PS: I think I found why monitor POSSIBLY went dark, and turned after i touched the menu button, the monitor was plugged through middle splitter (power) that just did ZZZ when i touched the monitor power plug, I moved now monitor directly to the main splitter. Lets see if it happens again, hope not!
