I had a similar question that I posted and as you can see I got no response:

Anyhow, my videocard(nVidia gf4 Ti 4400) that I used although with DVI out is probably without HDCP, I tried it with my slightly newer model Sony(WE620) and can only get the 1280x720 to work with a bit overscan. nVidia's driver allows for easy adjustment to solve that problem, but I can't get any higher res to work without some crazy flickering, and it even flickers at some lower res in other environment like in game as well...
