Hi guys. Yesterday i run Prime 95 for test cpu. But earlier i use option Never in Turn Off the Monitor in Disable Power Management. Then when after some hours i came back and see whats happen and i see that my screen just turns off ( yellow light ). Then i just turn my mouse and screen goes back to normal. But i am asking why? Like i say i use option TURN OFF THE MONITOR to NEVER in Power Management. 0 errors in Prime 95 and test is on 20 hour now. So? Maybe overheating ? But why my screen just turns off without reason?

Did you make sure the setting you changed was for the power plan you are on?
Did you set the 'Dim the Display' to never or made sure its brightness setting was not al the way down.
Did you apply the settings and then click ok? This is if you used the advanced settings in power options.

Have you changed the setting in both Control Panel and your graphics card driver?

In graphic driver not. But i dont think that is neccesary. But yesterday i left again computer in 15 hours while testing prime 95 and screen dont shut off. So i am asking why monitor earlier turn off after maybe 8 hours?

Maybe it's a preset power saver option, I don't know beyond that since it seems to act so randomly.

so it can be Preset Power Save Option and its randomly? That my monitor can shut off after 13 hours , but sometimes he dont shut off after for example 14 hours.

i repeat:

Why does my screen sometimes goes blank after a period of inactivity ( like 8 hours )? And sometimes not!. My monitor screen just turns off ( yellow light ). Then i just turn my mouse and screen goes back to normal. ITS TOTALLY RANDOM!

I disabled the screen saver and I disabled the option of the OS turning off the screen. Yet, the screen will still turn itself off after a period of inactivity. I'm currently using a Asus Monitor 19'.
