Monitor turns off after 10min (not screensaver or power settings)

Hello just few days ago monitor (Asus PG278Q) started turning off after 10 min while watching media or idle.

Checked screensaver: set to 'none'
Checked power settings: max performance, set to never shut down or sleep.

What else can turn off monitor except screensaver of power settings?

PC settings:
- i7-4790k
- asus PG278Q
- win 10 x64 Home
- 16GB PC2400
- SLi GTX 980 Ti
- 512GB M.2 for OS
- 4GB sata6 for media

Anything would be helpful, already loosing all hope.
Btw tried settings screensaver to some other and choosing 60 min but it still turns off after 10 min or earlier if set so it's not screensaver.

Hello snaf2k, and welcome to Ten Forums. :)

Double check using the tutorial below to see if you may have the display set to turn off after 10 minutes instead of "Never" or what you want.

Change Turn off Display after Time in Windows 10

If it's screensaver of power options - then already tried.

Nope, it's not. The tutorial link I posted will help show you more on how to check.

What do you mean "no it's not"? It was exactly about screen saver and power options.. I also went further and tried changing regestry "ActiveScreensaver=0" but seems that is same as regular screensaver option.

I'm out of choices.. guess will have to restore to factory defaults..

I mean what I posted is not related to the screen saver settings that you already tried.

I tried regular and registry screensaver settings.. you talking about something for noobs
