Preparing equipment and network for wireless broadcasting
The first step to successful synchronization is properly setting up your local network. It's crucial that the laptop and TV are connected to the same router. If one device uses a wired connection and the other uses Wi-Fi, streaming may fail due to client isolation in the router settings.
Make sure your router supports the standards 802.11ac or newer, as transmitting a high-definition video stream requires significant bandwidth. Older Wi-Fi standards may not be able to handle a 4K stream, resulting in constant buffering and audio desync.
