[mythtv-users] Pull my hair out over DVI->HDMI for my HDTV

John, it is a DVI limitation because your video card is sending a digital
signal to the TV and it's displaying 1:1. meaning one pixel from the video
card to one pixel on the TV. You won't be able to adjust the overscan or
scale the picture since it is a digital signal. Using a digital signal will
give you the clearest possible picture and it was what I wanted but I
changed my mind mid-purchase (and actually returned two TVs). I went analog
(D-sub) so I could scale the screen down to fit on the TV, I play lots of
games on my TV and in order to see the status bars on the edges of the
screen I had to switch to analog mode anyway (the DVI port cuts about an
inch off all four sides of the picture). Besides, I'm happy that I went
analog because I got Sammy's new 5678W which does 1920x1080p, the thing they
don't advertise is that you can't get a 1080p transmission over anything but
the D-sub plug. DVI/HDMI doesn't support those high bandwidths (yet?).

Good luck, and if you need more modelines, I have all the ones for my TV
from powerstrip.
