There are several image transmission protocols, each of which has its own operating features. Miracast allows you to duplicate the screen, and DLNA Used for streaming files. The choice of a specific method depends on your needs and the model of your smartphone.
Preparing equipment and checking the network
Before you start the setup, you need to make sure that both devices are in the same network conditions. TV and the smartphone must be connected to the same router. If you have a dual-band router, it is advisable to use the frequency 5 GHz to ensure maximum channel throughput.
Check the software version on your LG Smart TVOutdated firmware may not support new security protocols or video codecs. A system update often resolves issues with device visibility in the list of available gadgets.
