Basically i got this HDTV yesterday and have been playing my xbox 360 on it on the 1080p setting when i saw a line appear on the screen, i thought id measure it to monitor it, it was 1 half inches when i did it. Two hours later the line had stretched to 2 inches. It does this not only when im playing xbox but also when im watching sky. What is causing this? Is it my xbox or my tv's contrast/lighting settings?
All help appreciated
