begin searching for the TV to which your Miracast Adapter
is connected, or you may have to select "Add a device."
Note: If you do not see an option for "Add a device," you
are not running Windows 8.1 and will not be able to
mirror your screen using the Miracast Adapter.
10. Once the TV is found, select it.
The Miracast Adapter will now pair with the Microsoft
Windows 8.1 device. When the connection is made,
the TV will begin mirroring the device's screen.
