Xiaomi TVs (Mi TV A, Mi TV P1, Mi TV Q2, etc.) support several ways to connect a smartphone, from wireless protocols to wired adapters. But users often face problems: the phone does not find the TV, the picture slows down, the sound disappears or the screen is duplicated with artifacts. In this article, we will analyze all current synchronization methods (including hidden MIUI functions), optimal settings for Android and iPhone, and also give a checklist for troubleshooting.
Important: the connection algorithm depends not only on the TV model, but also on the firmware version. For example, in the 2020 Mi TV 4S, Miracast requires the activation of the developer mode, and in the 2023 Mi TV Q1E, this feature is available out of the box.
If you just want to stream YouTube or Netflix videos, you can do Google Cast, but for games (Call of Duty Mobile, Genshin Impact) or document work, you'll have to use HDMI or Wi-Fi Direct with minimal latency, and we'll go through each scenario separately below.

The Miracast protocol (aka Screen Mirroring or Wireless Display) is the most popular way to duplicate the Android screen on Xiaomi TV without wires.
- 🔹 Low latency (around 50–100 ms) – suitable for simple games and video.
- 🔹 No Internet connection – it works via direct Wi-Fi.
- 🔹 Full support HD (on some models — 4K ideally).
Cons: On older TVs (Mi TV 3, Mi TV 4 until 2019) can brake at high load, and on the iPhone Miracast does not work at all (need a workaround - see section 4).

Turn Miracast on in your TV settings (Settings → Connection and Sharing → Wireless Display)|
Activate the "Screen Transfer" mode on your smartphone (the path depends on the Android version)|
