What should I do if it displays abnormal wireless screens?
The abnormality of wireless screen projection may be affected by the network, copyright, system, etc. The specific reasons are as follows: ① The projector and the mobile device are not on the same local area network. If the mobile phone is connected to mobile data, and the projector is connected to WiFi, the wireless screen cannot be achieved; ② The content is not supported by copyright protection. Some video content is protected by copyright and only supports viewing by the relevant client; ③ If there is a problem with the system operation, you can restart the relevant equipment and restore the network settings before trying the screen; ④ Network instability will affect the screening, and users can check the network status.
