I am not sure what you are trying to do but if you set up the displays
as not twinview, you can run mythfrontend on either one or both and
they will both have their optimal resolution.  I have a projector and
a TV and do this all the time.  I switch off the projector (actually
switch the output off with a DVI switch) then restart X to get the
display on the TV.  When the projector is on, I restart X and myth
shows up on the projector.  Each display looks perfect.  You can also
have both mythfrontends running at the same time but the remote goes
to both so this really doesn't work.  The keyboard only goes to one so
if you have a remote keyboard, you can control the one you want.  You
could also just shut down myth on the projector and start it on the
small display as a way to switch.  Just right click on the small
display and click on mythfrontend to start it. I just find restarting
X easier even though it sounds messy.

xorg.conf is below in case it helps.

That said, what are you using for a 7 inch display.  I would like to
add a small display in parallel with my TV in case I want to play a CD
or something.
