Hello.

I am having a issue with my second monitor witch is a flat screen from LG.
It is connected with a high quality hdmi cable, from GPU hdmi to LG hdmi.

If i am watching a movie, or a youtube video. I will see vertical stripes across screen like the pictures aint in sync.

Have been testing the cable with another PC and screen. And the stripes are not there.

Have yet not tested my LG flat screen with another PC. Not yet have the opportunity to do so.

Thank you so much for your help!

My system:
Motherboard ASRock Z77 Extreme4
GPU: Asus GeForce 670
CPU: i5 3570K @ 4.5 GHz

UPDATE
I have now tested with another system.
Was a laptop with a i3 and onboard GPU
NO STRIPES

So something is wrong with my system? But what could be causing the problem?
I have the Z77 from Asrock and i5
Been trying out both Onboard intel GPU and my externel GPU. With no difference.

Help me out please.



Kind regards swisz
