Detailed Description
GdkScreen objects are the GDK representation of a physical screen. It is used
throughout GDK and GTK+ to specify which screen the top level windows
are to be displayed on.
It is also used to query the screen specification and default settings such as
the default colormap (gdkScreenGetDefaultColormap),
the screen width (gdkScreenGetWidth), etc.
Note that a screen may consist of multiple monitors which are merged to
form a large screen area.Signals

The ::composited-changed signal is emitted when the composited
status of the screen changes
Since 2.10

monitors-changed(screen, user.data)-
The ::monitors-changed signal is emitted when the number, size

may be a possibility.
