Kugou Music TV can mirror the screen through the following steps:

1. Make sure your TV and mobile phone or computer are connected to the same Wi-Fi network.

2. Open the Kugou Music TV APP and select the music or video you want to play.

3. Click the "Cast Screen" button in the upper right corner of the screen.

4. Select the device you want to mirror from the pop-up list.

5. After the connection is successful, your music or video will be played on the TV.

Note: The screen mirroring function requires your TV to support DLNA or AirPlay protocol. If your TV doesn't support these protocols, you can use a third-party screen casting device, such as Chromecast or Apple TV.
