Usually it is only 1 physical screen in which case the single value is
certainly meaningful. Even in the multiple physical screens case, as
mentioned elsewhere in this thread, that need not be a showstopper.

You can override it on an output-by-output basis with randr-1.2, that
makes more sense than a system wide (for that users toolkit) override as
the GNOME Control Center exposes.
