Why Bluetooth is not always the obvious choice
Xiaomi’s modern TVs and smartphones support dozens of interactions, from classic HDMI to advanced protocols like Miracast or Google Cast. But Bluetooth is often left in the shadows – it is perceived as a technology for headphones or speakers, not for synchronization with TV. Meanwhile, this is one of the most versatile methods, especially if you need to transfer sound from your phone to your TV without wires and without delay (which is relevant for watching movies or streaming music).
The main problem is that not all users know that Bluetooth on TVs often works “one-way”: many models support only audio output (for example, for connecting wireless headphones), but not receiving audio from external devices. In this article, we will discuss how to check the compatibility of your TV, configure a connection on Xiaomi (including the models of Redmi Note 12, POCO X5, Mi 13), and what to do if the TV “can’t see” the phone.
Spoiler: If your TV is released before 2018, the chances of a successful connection are minimal — manufacturers have only started to massively introduce Bluetooth reception in recent generations.
