If the device cannot be searched when casting TV screen, there are three reasons for this:
1. It may be that the TV and the screen-casting device are not connected to the same wireless network. Just need to check the network of the device;
2. It may be that the connected wireless network signal is unstable, causing problems with the device connection. This requires restarting the router or shutting down other devices in the wireless network;
3. It may be that the screen projection function on the TV is not turned on, so the corresponding device cannot be searched. You need to find the wireless screen projection function in the TV's settings and click to turn it on.
