Before you begin
A few things to know before you start:

You need to plug the Microsoft Wireless Display Adapter into a USB charging port, as it
draws power from the USB connection.

The adapter works best if you have both an HDMI port and a USB charging port on your
HDTV, monitor, or projector.

If the device you're connecting to doesn't have a USB charging port, plug the USB end of
the adapter into the USB charging port on a
station, or any other USB charger.

If your Surface is running Windows 8, you need to upgrade to Windows 8.1 or Windows
10 before you can use the Microsoft Wireless Display Adapter.
