Display device handlers are used to initialize the display device registry data. Different handlers can be implemented according to the defined interface, for example, via Xinerama or XRandR. With those registry data, EnumDisplayDevices, EnumDisplayMonitors and GetMonitorInfo can be built on top of it.
