I've just upgraded to Windows 11, in the hope of seeing the back of this problem, but a day later...it's back. It's always the same monitor. There are 3 displays connected to my graphics card (ZOTAC GeForce GTX 1660 SUPER 6GB):
- AOC Q27B3MA QHD monitor - connected via Displayport (this is the one that goes blank)
- AOC Q27B3MA QHD monitor - connected via HDMI (this is the main display, and never goes blank)
- Hisense HD TV - connected via Displayport with an HDMI adapter (this never goes blank, and is turned off 99% of the time).
I have the refresh rate set to the lowest value (59/60HzHz) on all displays, and have disabled G-Sync on all displays using the Nvidia Control Panel.
I was really hoping that Windows 11 would have resolved this :0(
