I only have this problem with Halo games. I am using a flat panel 37in LCD. I have the TV set for widescreen and the Xbox 360 set for 1080i. Although, this crops the screen leaving two to three inch black bars on either side of the screen and making the screen much smaller than my 37 inches. The only way to correct this is to set my TV for automatic which then cuts the edges off the picture and makes the screen appear rounded. Can someone help me get the most out of my screen?
