With some devices, like laptops and tablets running Windows, you can give a presentation at the front of the room and use the Surface Hub touchscreen to control your device, no matter where it is in the room.
To control your device from the Surface Hub touchscreen, plug in both the video cable (HDMI, DisplayPort, or VGA) and the USB cable to your device. The same goes for using the Surface Hub pen, mouse, and keyboard.
If you’re using a device running Windows 10, you can control it from the Surface Hub without cables. Just connect to the Surface Hub wirelessly. For more info on how to connect, see Project wirelessly with Miracast.
