Broadcasting content from your phone, tablet or computer to Xiaomiโs big screen TV opens up new possibilities for watching movies, games and presentations. However, many users face difficulties in setting up wireless or wired communications โ especially if they are Android TV models or proprietary PatchWall shells. In this article, we will discuss all current broadcasting methods, including hidden functions and solutions to problems.
It is important to understand that the method of connection depends on three factors: the model of the TV (for example, Mi TV Q2 2023 vs Redmi Smart TV X50), the source of the signal (Android/iOS/PK/Macbook) and quality requirements (resolution, latency, sound).
1. Wireless broadcast on Miracast (Screen Mirroring)
Miracast is a wireless broadcast standard supported by all Xiaomi TVs on Android TV (starting with version 8.0) that allows you to duplicate the screen of a smartphone or PC without connecting to a single Wi-Fi network, but has delay limits (up to 100 ms) and resolution limits (maximum 1080p@60Hz on most models).
To activate Miracast on your TV:
- Open Settings โ Connections and Sharing โ Wireless broadcast.
- Select Miracast or Screen Mirroring (name depends on the firmware version).
- Activate the option to Allow Connection.
On the Xiaomi/Redmi/Poco smartphone:
- ๐ฑ Go to Settings. โ Connections and sharing โ Screen broadcasting.
- ๐ In the list of available devices, select your Mi TV. TV.
- โ๏ธ At the first connection, a confirmation may be required. PIN-code (displayed on the TV screen).
โ ๏ธ Note: On Xiaomi TVs with firmware older than 2021, Miracast may not work with Android 12 smartphones+ The solution is to upgrade the TV software or use alternative methods (see section 3).

If the broadcast is interrupted, try to reduce the screen resolution of the smartphone to 720p in the developer settings (Settings โ About phone โ Assembly number โ tap 7 times).
2. Broadcast via Google Cast (Chromecast built-in)
Xiaomi Android TVs (such as the Mi TV A2, X Pro series) have built-in support for Google Cast, a technology similar to Chromecast. It allows you to stream content from supported applications (YouTube, Netflix, Chrome browser) without duplication of the entire screen, which reduces the load on the network.
How to use:
- Make sure your phone and TV are connected to the same Wi-Fi network (5 GHz recommended for stability).
- Open an app that supports Cast (like YouTube).
- Click the broadcast icon (๐บ) and choose your Mi. TV list.
List of apps that support Google Cast:
- ๐ฌ YouTube, Netflix, Disney+
- ๐ต Spotify, Yandex Music
- ๐ Google Chrome browser (broadcast tabs)
- ๐ฑ Google Photos (slideshow display)
| Model TV | Support for Google Cast | Max, permission. | Delay (MS) |
|---|---|---|---|
| Mi TV Q2 2023 | Yeah (built-in) | 4K@30Hz | 50โ80 |
| Redmi Smart TV X50 | Yes (renewal required) | 1080p@60Hz | 60โ100 |
| Mi TV 4S (2018) | No (only Miracast) | 1080p@30Hz | 100โ150 |
3. HDMI Connection: When Wireless Methods Fail
If your Xiaomi TV doesnโt support Miracast or Google Cast (like models before 2019), or you need a minimum response time for games (<20 ms latency), use a wired HDMI connection.
- ๐ฑ For smartphones: adapter USB-C/Micro-USB โ HDMI (for example, Xiaomi USB-C to HDMI).
- ๐ป For PC/laptops: standard cable HDMI 2.0 (for 4K@60Hz).
- ๐ฎ For gaming consoles: cable HDMI 2.1 (for 4K@120Hz on Mi TV Q2).
Instructions for Xiaomi smartphones:
- Connect the adapter to the USB-C port of the phone.
- Connect the adapter to the TV with an HDMI cable.
- On the phone screen, select Display mode on the external screen (you may need to enable USB debugging in the developer settings).
โ ๏ธ Note: When connecting smartphones Redmi Note 11 and later via HDMI Solution: In the TV sound settings, select the source. HDMI ARC or use a separate 3.5mm audio output.
Does your phone support HDMI output (check in specs)
Is there an HDMI port with ARC support (needed for sound)
Whether the cable length is sufficient (โค3 m is recommended for 4K)
Is the TV software updated (older versions may not recognize adapters)

4. Stream from iPhone/iPad to Xiaomi TV (AirPlay)
Xiaomi TVs on Android TV 11+ (e.g. Mi TV Q2 2023, X Pro 2026) support Apple AirPlay, a wireless streaming technology from Apple devices. This allows you to duplicate the screen of an iPhone or iPad without additional adapters, but with some restrictions:
- โ It works with iOS 12.+ and macOS Monterey+.

5. Broadcast from Windows/PK/Mac: alternative methods
If standard methods donโt work, consider customized PC solutions:
For Windows 10/11:
- ๐ฅ๏ธ Built-in projection: Win + P โ Connect to a wireless display (requires Miracast on TV).
- ๐ Through the browser: Open Chrome, click โฎ โ Broadcast and select Mi TV (Google Cast).

For macOS:
- ๐ AirPlay: Click on the screen management icon in the menu bar โ Choose Mi. TV.

For Linux, we recommend scrcpy with --display 2 support for external screen broadcasting.
sudo apt install scrcpy
scrcpy --display 2 --bit-rate 10M6. Problem Solving: Why the Broadcast Doesn't Work
If the Xiaomi TV isnโt detected when trying to stream, check out the following points:
| Problem. | Possible cause | Decision |
