I've got a scan lines (horizontal) going up as if It's scanning a paper!?
This only occurs when playing (all) games without VSYNC. Leaving VSYNC on solves the problem but I'm more used to play on higher framerate. Movements feel very slow when leaving it on (especially on FPS games).
I've taken screenshots but it's not visible.
Also there's something fishy going on:
-my graphics card is not overlocked
-Not overheating when leaving vsync off (remains below 60C)
-I'm using the official MSI drivers
for my MSI GTX 560 Ti Twin Frozr OC edition (ForceWare 280.26)
-Using VGA cable with a DVI adapter for my graphics card
