A display system is described that extends the functionality of a mobile display device such that video content generated thereby can be displayed by a different display device. This may be achieved when the mobile display device is engaged with a docking station that includes a video interface for connecting the docking station to the different display device. When the mobile display device is engaged with the docking station and the docking station is connected to the different display device via the video interface, video content can be routed from the mobile display device to the different display device.
