Do you want to show pictures from your vacation on the big screen, run a mobile game on your TV, or stream a movie from your phone without any extra wires? Connecting your smartphone to Xiaomi TV opens up a lot of possibilities, from mirroring to streaming in high resolution, but not everyone knows that the way you transmit an image depends not only on the model of the TV, but also on the firmware version, the type of connection, and even the brand of smartphone.
In this article, we will discuss all the current methods of transferring screens to Xiaomi TVs (including the Mi TV A series, Mi TV Q, Redmi Smart TV and others), as well as how to avoid common errors, from lack of signal to problems with audio delay, focusing on wireless technologies (Miracast, Wi-Fi Direct, Google Cast), which work without additional adapters, and check which ones are supported on old and new models.
1. Connection methods: which one to choose?
Before you start setting up, determine which type of connection is right for you, which determines the quality of the broadcast, latency and even battery consumption of your smartphone.
