Hello everyone, I am Time Customer Service Time Jun, I will answer the above questions for you.
If you cannot search for screen projection devices, it is generally a problem with the equipment, and not all boxes can support screen projection. The solution is:
1. Check whether the network is interrupted
When your phone wants to project screens with a TV, if you cannot search for a TV device, you can restart the TV's screen projection function and the router at home, then turn on the router and TV's screen projection function and try again. If you still can't find the TV device, then turn on the hotspot of your phone, connect the TV to the hotspot of your phone, and then search. There should be no problem.
2. Check for application updates
If you use a screen projection application that comes with your phone, you can search for the TV device at home to project the screen, but now you can't find the TV, then it is recommended that you check whether there is a new version of the screen projection application, if there is an update, and then try to project the screen. If the mobile phone system has an updated version, try to project the screen after the mobile phone system is also updated.
The screen projection can easily project photos and videos from the computer onto the TV and then directly play. TV refers to a device that uses electronic technology and equipment to transmit active image and audio signals. It is an important broadcast and video communication tool. The TV was first invented by British engineer John Logi Baird in 1925 and is mainly composed of signal systems, scanning systems and power circuits. The working principle of TV is to use the visual residual effect of the human eye to display frames of gradient still images to form visually active images. Differentiate between usage effects and appearance, TVs are mainly divided into 5 categories: flat-screen TVs, CRT imaging tube TVs, rear-projection TVs, projection TVs and 3D TVs. Modern TV is mainly divided into several categories such as network TV, digital TV, Internet TV, mobile TV and outdoor TV.
