+ Applications open a display to show <glossterm

+ In GDK, a display is represented by a

+ GDK inherited the concept of screen from the X window system,
+ which considers a screen to be a rectangular area, on which
+ applications may place their windows. Each screen has a
+ <glossterm linkend="rootwindow">root window</glossterm> which
+ defines the area of the screen. Screens under X may have quite
+ dissimilar <glossterm linkend="visual">visuals</visuals>.
+ Each screen can stretch across multiple physical monitors.
+ In GDK, screens are represented by
+ <link linkend="GdkScreen">GdkScreen</link> objects.
