I have an LCD TV with a DVI-D input that I want to use with my new Vista PC.
(TV is Sharp Aquos LC-37D7U, video adapter is MSI NX7600GT).

When I boot the computer, I see the early boot messages in 640x480, then I
see the Windows Loading message. After that I hear the sound that is played
when it is time to log on, but no image shows on the TV. Yes, the TV is set
to PC (DVI) input.

If I connect my Dell monitor, log on, set resolution by hand to 1280x720,
then change the cable to connect the TV, the TV displays correctly. But if
the computer sleeps, the screen is blank when it wakes up.

The graphics adapter also supports HDMI, but when I connect with an HDMI
cable and set to HDMI input, I get no picture at all.

I want the TV to display in the correct mode on booting or wakeup without
having to have a second monitor and the cable-switching routine.

Any ideas on how to fix this?
