I am cuurently usin an ATI 9600XT and a nVidia 6800 Ultra to connect to my TH-42PA20 panasonic plasma (edtv) through DVI and I have major overscan issues. I have been trying to get som assistance in reducing the overscan but I have not had any luck yet. I am using Windows XP Pro, powerstrip, and theatertek. With the ATI 9600XT, I was able to get 1776x1000 resolution to work with no overscan, but when playing DVDs I was getting tearing in the image. When I switched to the nVidia 6800 Ultra I didn't get any tearing but I have a lot of overscan. If there is anyone out there that can assign us with our setup, PLEASE HELP.
