+ * @Title: GdkMonitor
+ * @Short_description: Object representing an output
+ *
+ * GdkMonitor objects represent the individual outputs that are
+ * associated with a #GdkDisplay. GdkDisplay has APIs to enumerate
+ * monitors with gdk_display_get_monitors() and to find particular
+ * monitors with gdk_display_get_primary_monitor() or
+ * gdk_display_get_monitor_at_window().
+ *
+ * GdkMonitor was introduced in GTK+ 3.22 and supersedes earlier
+ * APIs in GdkScreen to obtain monitor-related information.
