any ideas what this may be. I hadn't noticed it because I typically play games in the dark, and the bar is very thin, though it runs the height of the screen it is only about 1 inch wide. I play using component cables, and usually set in progressive scan mode. My tv is a Sony KP51WS20. Any ideas?
Yeah I've noticed that. It's a common thing, I guess. I don't think it has anything to do with the cables. You can try moving the screen in the TV menu
