Broadcasting the screen of Xiaomi smartphone on the big screen of the TV opens up new possibilities, from watching movies in high resolution to showing presentations or streaming games. However, many users face problems โ connection is interrupted, picture slows, TV just can not see the device. In this article, we will analyze all the current ways of connection (including hidden MIUI functions), compare them in speed and stability, and provide solutions for typical errors.
Itโs important to understand that the way you stream depends on your TV and smartphone model. For example, the Xiaomi 13 Pro supports Miracast and Google Cast, and the budget Redmi Note 12 may require additional adapters. We tested all options on Samsung QLED, LG OLED, Xiaomi TV and Sony Bravia TVs โ the results are summarized in a comparative table below.
