It allows control over whether a cloned display prioritizes the internal or external monitor i.e. setting its preferred resolution source. Internal sets the resolution of the main display as the source on both screens. External sets the resolution of the connected (external) display as the source on both screens. Default uses the system's default behavior determined by Windows Settings.
