The difference between “video projection” and “wireless projection (screen image)”
Many users confuse the terms “video projection” with “wireless projection (screen image),” thinking they mean the same thing. In fact, “video projection” and “wireless projection (screen image)” are completely different concepts.

Video projection means that the mobile phone video content is pushed to the large screen for viewing. After the push is complete, the large screen only displays the video content, while the mobile phone can narrow the video interface for other mobile operations.

Wireless screen projection (screen mirroring) refers to synchronizing the content of the mobile phone screen with that of the large screen through the screen projection protocol or screen projection device. After the wireless projection operation is completed, any screen picture changes on the mobile interface will be displayed synchronously on the large screen.

Video projection Only allows you to display video content in a family setting and watch the video together. Wireless screen projection is used in enterprise office, product release, intelligent education and other commercial screen projection scenes.

Principle of video projection screen

The video projection channel has DLNA projection screen and airplay projection screen and Lelink(Le broadcast projection protocol) these three protocol channels. With the protocol channel, the phone and the TV set up a channel by pairing each other. When the connection is complete, the phone can transmit the video to the TV, which then starts playing the video.

If the TV has no screen projection function or the APP you use does not support video projection, you can only buy professional wireless screen projection equipment and use the function of screen mirroring to complete the operation and meet the needs of screen projection.
