Hello!

I have a problem that mostly occurs when I'm running games that has fast flickering lights like horror games in full screen mode. When the lights in the games gets too intense, black horizontal flashing lines appears on the screen. I have tried with another monitor but with no change. I have not over-clocked and the cooling is very good. I have all the latest drivers installed. I can run the games in window mode without getting the horizontal lines.

Do someone know a fix or what's causing this in full screen mode only?

Hello and welcome to the forums
Turn on V-sync and test again.

Vsync causes performance loss and huge input lag even with triple buffering on.

I can run the games in window mode without vsync turned on and I'm not getting any horizontal lines.

Is there a way to get the same results in fullscreen mode without turning on vsync just like in window mode?.

V-sync may lower the FPS,but sometimes it take care of some bugs in the game(I tried it and worked on some games)
