Hi /g/ i need your help.
I bought a BenQ XL2420T this week and i have a problem with it i have never encountered before with any monitor.
The screen keeps flashing in sections, displaying parts of the screen where they aren't suppose to, it starts near the top with a black bar and then goes down, smaller vertical blackbars also appear on the sides, they nearly always only appear when something on the screen is moving, it looks like part of the screen are being rendered not where they are supposed to.
I tried recording it but it doesn't show in the recording. I've searched for hours on the internet and i haven't seen this problem mentioned anywhere else.
Tried both 120hz and 60hz mode and the problem is the same in both modes, also tried hooking up my old monitor (60hz) as second screen and it runs just fine.
My GPU is a 5670 in case you want to know.
I'm probably going to RMA it unless i can find a way to make it stop but i wanted your input before i do so.
I would really appreciate any info you can give me.
