I guess this does the same thing that -geometry 1280x720 does.  At least
I see no different result.

Some progress:

mythfrontend -w -geometry 1280x720 -O XineramaScreen=0 -O

works.  I can now display a frontend on the desk screen with the sound
routed properly, but no combination of

-0 GuiHeight=720 -O GuiWidth=1280 -O GuiSizeForTV=1 (this was set to 1
in the database too) -O AspectOverride=1

display the video properly on the desk screen (1920x1200).  the video
has 2 vertical bars on the sides and is stretched vertically.  In fact,
with some combinations of parameters the bars are wider and the video
looks even more stretched vertically.

If I just do:

mythfrontend -O XineramaScreen=0 -O AudioOutputDevice=ALSA:default

The frontend displays on the correct screen, it doesn't take the whole
screen, just the top 1080 pixels from the top, but the video is still
stretched vertically with the 2 black bars on the sides.

If someone can point me to the magic parameter (or combination of
parameters) that affects this problem, it would be great.  At least now
I can do housekeeping like I used to before the screen upgrade.

Thanks for the help so far.
