I recently changed my video card output from S-video>component, to DVI>HDMI on my HDTV. Now, all of my games edges are off the screen (does that make sense?). Tried several different screen resolutions, couldn't fix the problem. When I changed back to the S-video>component input, the problem went away. fine, but I'd like to take advantage of the better resolution that DVI offers.
Ahh...you need to use your TV remote. Under Options, see if you can find Screen Resolution, or Aspect Ratio. There'll be 4:3, 16:10, 16:9, 5:4, etc. Flip through them until you find the one that's right for you.
