I want to ask why Netease Cloud Classroom failed to block Huawei TV. If the signal is not good or Huawei TV does not have this function, you can try to project the screen with the help of third-party software. The operation steps are as follows:

1. With the help of the mirroring function in the third-party software "Le Broadcast Projection Screen", users can synchronize the video images of Netease Cloud Project Hall on the big screen in real time;

2. First, select the TV you want to connect on the home page of Leibo Projection app. If you can't find the TV signal, try scanning the QR code in the lower right corner of the TV to connect.

3. After successfully connecting to the TV, open the Netease open class app on the mobile phone, and you can project the picture in real time through the mirror function of the music broadcast projection screen.
