You'll learn how to avoid image lag, why your TV might not detect your phone, and which router settings might be blocking the connection. Even if automatic detection doesn't work the first time, manual setup can help resolve the issue.
Preparing devices and checking the network
Before setting up the broadcast, you need to make sure your equipment is ready for data exchange. A basic requirement is the module Wi-Fi on both devices and their active participation in the local network.
