Broadcasting your smartphone screen to your big TV screen is one of the most popular features for Xiaomi owners. Whether you want to show photos from your vacation, run a mobile game on a 65-inch display or stream a movie from Redmi Note 12 to Xiaomi TV A2, there are many connectivity options, but not all of them are equally convenient: somewhere you need to buy an adapter, and somewhere there are enough built-in technologies like Miracast or Google Cast.
In this article, we will discuss all the current broadcast methods, taking into account the features of MIUI firmware and Xiaomi TVs (including Mi TV 4S, Redmi Smart TV models, etc.), you will learn how to avoid common errors like โfailed to connect to the deviceโ, why the image can slow down, and which method to choose for minimal delays. And also compare wired and wireless solutions on 5 key parameters: speed, quality, stability, cost and complexity of settings.
Spoiler: If you have a Xiaomi Redmi on MIUI 14+ and a TV in the same ecosystem, you're lucky that the manufacturer has made it as easy as possible. Owners of other brands will have to work a little harder, but there's a solution for them.
1. Wireless broadcast via Miracast (built-in MIUI function)
The easiest way for owners of Xiaomi Redmi and Xiaomi TV is to use Miracast technology, which is built into the MIUI firmware since version 12. It allows you to duplicate the screen of the smartphone on the TV without additional devices, but with some restrictions:
- ๐ฑ It only works on devices with MIUI 12+ (Check in the settings โ The phone).
- ๐บ The TV should support Miracast (all Xiaomi models) TV After 2019, we support).
- ๐ Maximum broadcast resolution โ 1080p at 30 Hz (some models may have 60 Hz, but with artifacts).
- ๐ฎ Delay (input lag) - about 50-100 MS, which is critical for dynamic games.
To begin the broadcast:
- On TV: open Settings โ Connect and Sharing โ Wireless Display (or Miracast).

โ ๏ธ Note: If the TV is not listed, check if it is enabled with Visibility for All Devices in Miracast settings. Some Redmi models (e.g. Redmi 10) may require a phone restart to reset network settings.

2. Streaming via Google Cast (Chromecast) โ for streaming content
If you donโt need to duplicate the entire screen, but only stream videos from apps (YouTube, Netflix, Movie Search), then Google Cast technology (aka Chromecast) will work better. It is more stable than Miracast, supports 4K resolution and has lower latency.
Important: Xiaomi TVs have built-in support for Google Cast, but the smartphone must have an app that can broadcast content (for example, YouTube or Google Photos).
- Connect your phone and TV to the same Wi-Fi network (required!).
- Open a supported app (e.g. YouTube).

- ๐ฎ You can continue to use your phone during the broadcast.
โ ๏ธ Note: Some apps (e.g. Netflix) block streaming to non-certified devices. TV not appearing in the list, try using the official Chromecast or update the TV firmware.
