Hello dear cummunity,
first time posting something.

My problem are horizontal moving lines on the screen.
It doesnt really look like screen tearing, more like blurry thin lines moving up and down across the screen.

I have already tried turning on V-Sync but that didnt help.
I have tried installing the latest drivers for my gtx 960, didnt help either.
I have also tried using another screen -> same problem.
I have tried using different cables to connect pc to LCD (HDMI & DVI-D) didnt change anything, but noticeable was that the screen only responds when i connect the cables directly to the GPU connecting to the motherboard didnt work.

Strange is that i dont have the problem when playing games aE Skyrim on highest settings it only occurs when watching videos.

My Specs:
CPU: i5 4690
GPU: GTX 960
MB: Asrock Fatl1ty Killer z97x
LCD: Benq RL2455HM

I really dont know what to do, i hope someone can help.

Kind regards Gabriel
