I've connected my PC to my TV via HDMI (I've also tried using DVI). Whatever the resolution (anything from 800 x 600 to 1080p), the image displayed on the TV does not fill the entire screen surface; there's a black border on the edge of the image. This happens in both Vista and Windows 7.
After a bit of searching I came to the conclusion it's got something to do with overscan done by the graphics card (ATI 3200HD). It's definitely not the TV because on my old PC there were no such problems. I've searched for the option in Catalyst Control Center 9.9 but it's not available for the TV; if I connect a normal LCD display, the option is there, but only for the LCD screen. If I choose Configure for my TV, where the overscan option should be, it takes me to the Welcome tab in CCC. How can I make the image fill the entire screen? How can I enable/disable overscan for my TV?
