[mythtv-users] different mythfrontend resolutions in cloned twinview mode

What I am looking for is a way to display the SAME mythfrontend instance on
two different displays with two different resolutions at the same time.
The 7" tft should display the mythfrontend with 800x600 and the projector
with 1280x720 at the same time. But there is no way set a resolution per
display. I can tell mythfrontend which display to use as a primary one even
in a cloned mode. mythfronted is setting its resolution to that one
automatically (depends on the setting). If the smaller display is set as the
primary one mythfrontend is shown with 800x600 on the projector. The other
way around if the projector is being chosen as the primary display
mythfrontend resolution on the 7" tft is 1280x720.
I haven't picked up a particular display yet. There are a lot of them in the
internet.
