Can't seem to figure this out. When playing videos full screen on netflix or any other video player, I get this horizontal line about 4 inches down from the top of the monitor. It's annoying. It's similar to those lines that appear on worn VHS movies. It only occurs when the camera is moving and not when it's at a standstill watching a scene. Hard to explain but an example would be watching Lost and the camera was swaying through the jungle pretty quickly and the line appears and distorts the image a bit. It's not a major issue but once you are aware of it, it gets annoying. It seemed to appear recently because I watch a bunch of videos on netflix before and never had it. I'm using my gaming pc with a 25" HP LCD monitor.
Anyways what could cause the annoying line?
