This chapter explains how to connect RTL8812AU-CG for the first time to the source device.   
3.1.   Connecting using Miracast on Windows 10 
Miracast is a peer-to-peer wireless screen display standard created by the Wi-Fi Alliance. It 
allows a portable device like a laptop or smartphone to wirelessly send  up to 1080p HD 
video and 5.1 surround sound to a compatible display, like an HDTV.   
A Miracast compatible Ultrabook™, PC or Tablet device captures the audio and graphics 
data and encodes it as H264 video stream for transport. This information is then sent by the 
device via Wi-Fi through a Wi-Fi Direct connection to a receiver connected to the display 
device. The receiver then decodes the video signal and passes it to the TV display (or other 
display device). 
This section explains how to connect a device running Windows 10 to RTL8812AU-CG. 
1.  Click the Notification icon on the task bar or press the shortcut keys, Windows logo
