Broadcasting a smartphone screen to a large screen Xiaomi TV opens up new possibilities, from viewing high-resolution photos to streaming games or presentations without connecting a laptop. However, many users face problems - the TV does not find the device, lags occur or the image is transmitted with artifacts. In this article, we will analyze all the current ways of screen duplication (including hidden MIUI functions), compare them in speed, quality and compatibility, and provide solutions for typical errors.
Itโs important to understand that the methods differ not only in connection type (wireless/wireless), but also in protocols supported. For example, Miracast works on Android devices, but may not be supported by older Xiaomi TV models (until 2019). iPhone owners will have to use AirPlay or third-party apps. We tested each method on Mi TV Q2 2023, Redmi Smart TV X 2022 and Mi TV P1 2021 โ the results are summarized in a comparative table below.

6. Solving broadcasting problems
If the image is not transmitted or artifacts appear, check:
- ๐ Phone power: With a low charge (less than 20%), some devices block the broadcast.
- ๐ถ Wi-Fi signal: For Miracast and Google Cast, use 5 GHz (less interference).
- ๐ Reboot: Restart your phone and TV if the connection is not installed.
Typical errors and decisions:
| Problem. | Reason. | Decision |
|---|---|---|
| TV not visible on the list of devices | Wi-Fi Direct is disabled on TV | Enable Settings โ Network โ Wi-Fi Direct |
| No sound is transmitted. | DRM-limitations in the annex | Use Google Cast or HDMI |
| Lags and brakes | Weak signal or processor overload | Close the background applications, connect to 5 GHz |

If neither method works, check the TV firmware version. On Xiaomi TV with Android TV 8.0 and below, you may need to upgrade to Android TV 9.0+ to support Miracast and Google Cast.
7. Comparison of methods: which one to choose?
The choice of the broadcast method depends on your tasks:
- ๐ฎ For games: Only HDMI (minimum delay).
