I have a Radeon HD 6870 in my PC and had it hooked up to a 41" LCD tv with no problems. I recently bought a 55" screen tv, but when I use it as a computer screen there is a black border around the screen (1" top and bottom and 1 3/4" on the sides). Does anyone know of a way to fix this? I have the card set to it's max resolution (1920 x 10??). Would buying a second and crossfiring work? Or maybe I need to get a more powerful card? Any help would be greatly appreciated.
