I have the same motherboard and the tv encoder dot clock (used by
component out) has a 400MHz max dot clock. I don't know what the DVI
ports max clock is though. I think the point is moot though, as my 720p
is only 74MHz, and 1080i should be about the same.
I found the quality to be much better using the DVI port from that
motherboard to my Panasonic LCD Projection (720p) television. However
it only has 1 digital input on the back, which goes to the cable box for
now. What modelines are you using for your 1080 and 720p? My 720p
over DVI is razor-sharp. The NVIDIA drivers have built-in modelines for
standard resolutions too. I'd try the mode "1280x720_60" if you haven't
already. There's also "1920x1080_60" and "1920x1080_60i".
