Im not sure if discolouration is the right term but here is my issue, Every video regardless of source that ive downloaded over the last 2 days has had discolouration. It dosnt appear in any of my other videos so I don't think it is my monitor. I don't think its the video format not being able to play properly (they are all .mkv) as I have many more of that type that work. What else could cause this?
EDIT: thanks for moving this I completely forgot there was a computer section
