I have a monitor (CRT:) and a Panasonic TV (DFP:) and my Xorg.0.log, 
too, is anxious to let me know that they don't support 3D Vision.  The 
TV has an 'Overscan Off' setting in its menu, but it /ALSO/ requires the 
Aspect ratio, set from the TV remote, to be 16:9.  Then 
nvidia-auto-select works fine.  nVidia 304.119.   When I want Myth on 
the TV I use

#!/bin/bash
export DISPLAY=:0.1
mythfrontend --geometry 1920x1080+0+0
# mythfrontend --geometry 1860x1046+30+16

This provoked argument in a thread here last March, but in the end it 
was agreed to be justified.
