There is a firmware bug if this keeps turning off -- please contact Acer to report this issue. They may be able to give you a firmware update if it's a known issue & if model supports field firmware update by end user.
1. This is very GPU dependant.

2. How are you measuring the refresh rate? Via Control Panel or via TestUFO?
Many games and TestUFO has problems when more than 2 monitors are connected.
To prevent refresh rate interference, make sure:
1. The 390 Hz is primary monitor
2. Control Panel says 390 Hz
3. Your game is exclusive full screen on primary, not borderless
I have the monitor and i have to re-enable after every restart and i have notified acer about this. Would be good if as many as possible contact them though, might be fixed fasterChief Blur Buster wrote: ↑14 Sep 2021, 17:16There is a firmware bug if this keeps turning off -- please contact Acer to report this issue.

I've had my XV252QF for about a week and can confirm this issue. It appears to be an issue of the GPU really not enjoying 390 Hz. After reading what others wrote, I've decided to test it without any other monitors attached and suddenly 390 Hz "works". The catch is that my RTX 3090 Founders Edition really, really struggles with it. Suddenly I ran into GPU driver crashes and degraded performance. Everything is fine up to 360 Hz, but with 390 Hz it starts crashing and losing performance. No idea how that makes any sense and how a monitor's increased refresh rate could make a GPU go crazy, but it's reproducible for me.valgar wrote: ↑17 Sep 2021, 18:49
I've received my XV252QF from Amazon yesterday, sadly it has a bad flickering problem, the same shown in this video:

The problem presents itself only @390Hz with overclock active. It goes away as soon as I switch to 360Hz or less.
