RasPi screen config plug-in

I would like to see a screen configuration plug-in for the Raspberry Pi that offered a fixed ‘monitor type’ of GPU and offered a choice of various resolutions and colour depths, including ones used by games. No need for the ‘try’ button.

This could be done with a single MDF file for ‘GPU’.

Also desirable would be a note of what the GPU is sending to the monitor (if we can talk to the GPU yet).
