Broadcasting a screen from a Xiaomi smartphone to a Mi TV is a convenient way to show photos, videos or even games on the big screen without unnecessary wires. However, many users face problems: connection is interrupted, picture is slowed, you can not connect at all. In this article, we will analyze all the current ways of broadcasting โ from built-in MIUI functions to third-party applications โ and also tell you how to avoid typical errors.
The Xiaomi ecosystem is very different, because it offers multiple wireless content technologies, like Miracast, Google Cast, DLNA, and even Mi Share, but not all of them are equally stable. Miracast can be latent on older models, and Google Cast requires you to connect to a single Wi-Fi network. We tested each method on different devices, from Redmi Note 10 to Xiaomi 13 Ultra, and we identified the most reliable ones.
If you want to not just duplicate the screen, but stream a specific video (for example, from YouTube or Netflix), then you should use specialized applications. For gamers, a wired connection via USB-C โ HDMI will work, which minimizes delays. At the end of the article you will find a comparative table of all methods with the pros and cons of each.
1. Wireless broadcast via Miracast (built-in MIUI function)
Miracast is a wireless screen standard that supports all modern Xiaomi smartphones (starting with MIUI 10) and Mi TVs (series 4A/4S/5 and later), the main advantage of the method is that it does not require a connection to a single Wi-Fi network, since the devices connect directly to the Wi-Fi Direct protocol.
To begin the broadcast:
- ๐ฑ On your smartphone: open Settings โ Connection and sharing โ Screen broadcast (or Quick settings) โ Broadcasting).
- ๐บ On TV: Go to Settings โ Network and Internet โ Miracast (or Sources) โ Screen mirroring).
- ๐ In the list of available devices, select your Mi TV. Confirm the connection on both screens.
Speed depends on the phone and TV model. For example, on the Xiaomi 12 Pro and Mi TV Q2 75, the delay is ~100 ms, which is acceptable for video, but not for dynamic games. On budget devices like the Redmi 9A, you can experience slowdowns when watching Full HD.
โ ๏ธ Warning: If the broadcast is cut off, check if the connection is blocked by the power saving mode on the smartphone. โ Battery. โ Energy saving regime.

2. Broadcast via Google Cast (Chromecast)
If your Mi TV is running on Android TV (e.g. Mi TV Stick, Mi Box S or Google TVs), the easiest way to use is to use Google Cast, which allows you to stream not only the screen, but also individual apps (e.g. YouTube, Netflix, Twitch).

3. Wired connection via USB-C โ HDMI
For those who need maximum stability (for example, to stream games or watch movies in high resolution), the best option is wired connection. Modern Xiaomi smartphones (starting with the Xiaomi 11 series) support DisplayPort Alt Mode, which allows you to display the image via USB-C โ HDMI adapter.

| TeamViewer QuickSupport | โ Yes, for Android only. TV) | ~200 ms. | Requires installation of server part on TV |
| Screen Mirroring (by Google) | โ No, only for Chromecast) | ~100 ms. | It doesnโt work with Mi TV based on PatchWall. |
The most versatile option is ApowerMirror, which allows you to broadcast the screen even to TVs without Android TV, but requires a connection to a single Wi-Fi network.
- Download ApowerMirror from Google Play to your phone and TV (if you have Android TV).
- Run the app on both devices.
- On your phone, select M โ Mi TV from the list of available devices.
โ ๏ธ Note: Some apps (such as Netflix or Disney)+) Blocking broadcasts through third-party programs due to protection DRM Widevine. In this case, use Google Cast.
