My screen has a green glow around the edges more visible when in dark areas of a game or movie Not sure why this has happened but I have had the screen for about a year and haven't bumped or damaged it in any way. What could have caused this?
 
Wait. No. All three do it on the same on different computer? That is strange. What kind of monitor is it?
