  Not sure, but I have a slightly more complicated setup - 2 different TVs (via 
hdmi splitter) off the same front end.  One is 1080P + 5.1, the other 720p with 
just stereo.

  I set up 2 different profiles for the frontend, made up a simple script that 
calls nvidia-settings to switch the resolution and update a file to say what 
profile to use.  This is driven by the global key events in the frontend.

  I have a script that runs the frontend in a loop, so the above script kills 
the frontend and updates a file which says which profile to use, and that loop 
script then re-launches the fronted.  The loop script is handy just in case the 
frontend process dies for some other reason - in that case, it launches it with 
the same profile.

  (I also added some logic to handle running Kodi from the frontend - in that 
case, the frontend exits but the loop script just restart it until kodi exits).

  If there is interest, I can share these scripts.
