Why can't many hotel TVs be screened?

Many hotel TVs can't be screened for several reasons:

1. Screen projection requires that the mobile phone and TV are in the same LAN. If the mobile phone uses mobile data and the TV is connected to wifi, screen projection cannot be realized.

2. Some video contents are protected by copyright and can only be viewed in relevant video clients. It is forbidden to throw screens, record screens, take screenshots and other acts that may infringe the copyright of content.

3. If there is a bug in the system operation, the user can restart the relevant equipment, restore the network settings and then try to filter.

4. Sometimes the unstable network will lead to the failure of screen projection, and users can check the network status;

If the hotel TV is old-fashioned and can't be connected to the Internet, then the screen projection function can't be realized, and the user needs to connect an external TV box.
