Hi My friend and I have both got a samsung 50", his is slighty newer model tho. When I play a DVD on my xbox 360 I have a black border at the top and bottom of the screen. My friend does not and his plays the full size of the screen. The only way I can play fullscreen is to change the display to 'stretch' which looks quite bad. Both are connected via hd-av component. Please help guys! why is his playing the size of the screen and mine has a black border at the bottom and top?
