Vine and Switched-out desktops

I use Vine to control a switched-out user while the actual physical desktop is output to my TV running XBMC for OSX.

What I am wondering is if there is any way to add additional resolutions to the switched-out user’s options. I have several that are not supported by my TV (and thus do not appear when that user has access to the physical desktop) like 1680x1050, 1280x1024, etc.

I would like to be able to use 1280x960 on my switched-out desktop. Does anyone know how I could accomplish this?

There are a variety of solutions to this situation depending on your hardware and OS version.
