Stay connected when you need it most using this Microsoft display adapter. It uses WiFi to display everything from your device to a monitor. It is compatible with the Surface Pro 3, Surface Pro 4, Surface Book and Surface Laptop. Simply, plug one end of the adapter into the HDMI port, and the other into the USB port. The adapter then uses the 7m range WiFi to connect your devices. This connection uses Miracast technology to display all content on the big screen, regardless of the app or programme you’re using. This means it’s easy to stream movies, view photos and display presentations to the whole room.
