I have a sanyo 30inch hdtv with the hdmi connection. I was able to get it to work on XPpro with my 9800pro using a dvi to hdmi connector, there were some overscan issues but it worked. I upgraded to MCE 2005 and tried thre latest catalyst drivers 4.9 and uninstalled the catalyst control center. When I have the hdmi plugged in neither the lcd or hdtv would work when I unplugged the hdtv the lcd would work but not the otherway around. I then loaded Powerstrip and eliminated the problem with the hdmi being plugged in and no screen on the lcd but still I have a no signal message on the hdtv. In Powerstrip the tv info shows up and yes I have tried every available resolution.
