I’m with tomtuttle on this one. If your present video card has DVI see if you can find a DVI to Component adapter that will work with your card. If not then I go with his suggestion to get a new video card with DVI that had the capability to use a DVI to Component adapter. That way you get the functionality you want and likely a better video card than you have now.
As long as your video card can output 720 or better 1080 since your HDTV displays 1080i then you will see an improvement by upgrading from S-video which is only 480. It’s best to send your display a signal in it’s native resolution which in your case is 1080. I use my HDTV as a computer monitor at 1080 and it is great. I use my 1080p HDTV as my primary computer monitor and love it. If you are presently sending your HDTV a 480 signal via S-video you should some nice improvement by sending it it’s native 1080 signal so it doesn’t have to upscale the image.
