NOTE: I briefly considered posting this in the Monitor / Video forum, but I concluded that this was more of a software / driver issue, so I figured I'd be best off posting it here.
A week or two ago, I went and ordered a component cable dongle for my Radeon 9800, with the intention of using it in my arcade machine (I'm using a 20" SDTV for my monitor). The picture quality was very sharp, but unfortunately, I had some serious overscan problems. The Windows task bar nearly disappeared off the screen, and in a game like Mortal Kombat II, the upper half of the health bars and timer would be completely off screen.
I went into the Catalyst Control Center to see if the overscan could be adjusted like with an S-Video or Composite cable, but I had no luck. For now, the only 480i picture I can get over component cables is an overscanned one. I switched back to using an S-Video / Composite cable (my TV has no S-Video jack), but I really do miss the clarity that component out offered since it was nearly "arcade perfect," and composite most certainly is not.
So, does anyone know of a way to adjust the overscan on a 480i image over component cables? I've done a little googling on the subject, but I had trouble finding anything conclusive. Thanks in advance!
