Here are a few that work for my Sammy DLP via the DVI port:

        ModeLine     "1280x720" 74.2 1280 1390 1430 1650 720 725 730 750
        ModeLine     "ATSC-720-60p1" 74.2 1280 1320 1376 1648 720 722 728 750
        ModeLine     "ATSC-720-60p2" 74.2 1280 1320 1376 1650 720 722 728 750

I still get overscan that I can't adjust out with modelines.  Is that
is a DVI limitation?
