The problem is that the TV out really has a max. of 1024x768, so I think
you should not clone the main (analog) desktop.
You could set up TwinView to have one big desktop, where you can move
the mouse and windows from one to the other.
Or you set up a seperate X display on vt9 for example for the TV, that
