Also make sure your TV is set to scan a full frame. TVS default 16:9 setting will crop a bit because some analog shows and whatnot have junk picture around the borders which was common back in the day of analog television. Even some dvds have junk in the outer edges. Just see if you can find an option to change picture size. I know on my samsung, I have to set the tv to "just scan" instead of the 16x9 option otherwise my dock and menu bar disappears.
