That was it! Thanks very much. I set it to 16:9. It was originally 4:3 which I assume is the default because I've never paid attention to that screen.

StuartA: I only use my Myth box for TV and Music and it sits on MythFrontend 99% of the time unless I need to futz with something (and those somethings are getting pretty rare now) so I just wanted to dupe my main display on another screen near my kitchen.


Now, will the dual-head setup persist across reboots? All I did was tell nvidia-settings that the 2nd monitor was in the same position as the first and [Apply]. Do I have to do some xorg.conf stuff to make this permanent?
