I have an 6870 and using a Panasonic Viera 32" + 2x 19" LCD Monitors. using 60 Hz, None of these happens. Games that ran past 60, Most of the time I have to turn on Vsync to remove screen tearing. Games that are playing below 60FPS, I don't do anything. and Its fine on 60 Hz I didn't understand most of what you're saying but try this. 1. Plug-in HDTV 2. set to 60 Hz in the TV and the GPU Settings. 3. REMOVE ANY FRAME LIMIT 4. Set Vsync to "application controlled" in the GPU Settings and in the Games' Video Settings, turn vsync off. 5. Play a game. 6. If problem still there or if its fixed but you're experiencing some kind of screen tearing Turn Vsync on in the Games' Video Settings 7. Play a game. 8. If the image-doubling problem still exists try changing Monitors or Cables 9. If the problem exists Try using the HDTV on another build. repeating steps 1 to 7, If not its the HDTV/Cables. 10. If the problem still exists, its the HDTV, If not then its either the GPU doesnt like your HDTV or vice versa.
