How to connect Xiaomi phone to Samsung TV: all working ways

Connecting Xiaomi to a Samsung TV opens up new possibilities, from watching photos on the big screen to streaming games or working in DeX mode. However, users often face compatibility problems — especially when it comes to connecting devices of different brands. In this article, we will analyze 5 proven ways of synchronization, including wireless protocols (Miracast, Smart View), wired connections (HDMI, USB-C) and alternative solutions for older TV models.

It’s important to consider that Samsung is actively promoting its own Smart View standard (formerly AllShare Cast), while Xiaomi defaults to Miracast or Wireless Display.This can cause conflicts when connecting automatically. We’ll look at the settings of both devices in detail, and we’ll also give recommendations for correcting common errors – for example, when the TV can’t see the phone or the image slows down.
