Connecting Xiaomi to a TV via Wi-Fi: A Complete Guide with Troubleshooting

Wireless screen mirroring from a smartphone to a large TV screen has become a standard feature of modern devices. Xiaomi, Redmi And POCO can use several protocols to transmit images over Wi-Fi — from standard Miracast to proprietary solutions like Mi ShareHowever, in practice, users encounter problems: the TV doesn't detect the phone, the picture lags, or the sound is delayed. In this article, we'll cover all the current connection methods, including hidden settings. MIUI, and we will explain how to eliminate typical errors.

It is important to understand that the connection method depends not only on the smartphone model (for example, Xiaomi 14 Pro or Redmi Note 12), but also from the capabilities of the TV.
