[SOLVED] Duel display, secondary monitor randomly flashes black, screen itself is not turning off or losing power.

I have checked both ends of the display port, Main display is a Sumsung G5 32in 1440p secondary is a 27in 1080 which used to be my primary and had no issues with it until now,
Ive checked powersaving settings and theres no reason it should be flashing.


PC specs in my signature

If you don't mind, put the specs in the original post. It will help anybody with similar problem find your topic, as specs in signature can change with time.
As for your problem, I've seen such behavior caused by broken video cable so checking another cable would be first thing to do. Trying another output port on GPU would be next.

Fixed my own issue, secondary monitor was gsync compatible as soon as I turned it off it worked fine.
