If you use Apple products, then you must be familiar with AirPlay, which allows you to share (via streaming) multimedia content over a WiFi connection. One of AirPlay's best features is the ability to mirror the screen of your device on your Apple TV.
In order to duplicate the screen of a Windows PC on your Apple TV, you need to start by downloading and installing the AirParrot application on your PC.
After doing that, make sure that both devices are connected to the same Wi-Fi network.
Enable Airplay on your Apple TV. Then, launch AirParrot. Click Try AirParrot > OK.
Right-click on the AirParrot tray icon and select Apple TV:
Your PC screen should now be mirrored on your Apple TV.
