This is a very important bit. Some TVs do send bogus PnP information to a
PC vidoecard. Depending on the hardware family of card, this can completely
mess you up. The intel driver doesn't handle this well at all. OTOH, the
nvidia driver seems to do fine.
I have 2 TVs that send bogus EDID info. My i945 Macs aren't very useful
on either of those boxes. My nvidia based stuff handle them fine.
I've never tried to use audio over HDMI. I just use discrete inputs.
