I've put an image above showing my problem, but I still don't know if you can see it, or if it's just specific to my pc.
It seems to occur quite alot in dark areas, say if it's a dark video on youtube, a dark area in a game, anything like that.
I've tried messing around with the gamma settings, and it got a little better, but this morning when I turned it on again it was back to the normal green lines.

Please help D: Thanks in advance.
