Binary package hint: gnome-control-center

i tried to have my internal and the external monitor to mirror each other. (possibly at different resolutions - but this should be caught and warned).

if i set both displays first to the same resolution and aspect, mirror works.

it would be nice if a 'best' common resolution would be proposed for the user to select.
