When Xiaomi's mobile phone projects a screen on the TV, it always shows that the TV terminal needs authorization, and the problem is solved in two steps:

1. Open the wireless projection screen on the TV or an application like Miracast.

2. Turn on the wireless display in the wireless connection mode of the mobile phone. At this time, the name of the TV will appear on the phone. After the connection is successful, the mobile phone can be displayed on the same screen as the TV.
