Wirelessly streaming video from Xiaomi Redmi to a big TV screen via Wi-Fi opens up new possibilities for watching movies, streaming games or showing photos. However, many users face problems: connection breaks, sound is delayed, the TV simply canβt see the phone. In this article, we will examine all the current ways of transferring the screen β from built-in MIUI functions to third-party applications β and also find out why sometimes nothing works and how to fix it.
The feature of Xiaomi Redmi smartphones (including Note 10/11/12, Redmi 9/10/13C and others) is to support several wireless transmission protocols: Miracast, Google Cast and DLNA. But not all TVs are compatible with these technologies out of the box. For example, older Samsung or LG models may require additional settings, and some smart TVs (for example, Xiaomi Mi TV) work only with their proprietary protocols. We tested all methods on the current versions of MIUI 14 and Android 13/14 - the results are summarized in the comparison table below.
1. the built-in Wireless Display (Miracast) function is the fastest way
Miracast allows you to duplicate your smartphone screen on your TV without an internet connection β just enough for both devices to be on the same Wi-Fi network (or create one themselves). This method works on all Xiaomi Redmis with Android 8.0 and later, but requires Miracast support from the TV side. Check if your TV has Screen Mirroring, Wi-Fi Direct or Miracast functionality in your network settings.
To activate the broadcast:
- Open Settings on Redmi and go to Connections and Sharing β Wireless Display.
- Turn on the Wireless Display slider and wait for the available devices to be found.
- Select your TV from the list. PIN-code, enter it from the TV remote.
- Confirm the connection on both devices.
β οΈ Note: Some Redmi models (e.g. Redmi) 9A or Redmi 8) the function may be called Screen Broadcast or hidden in the menu Additional. If the TV is not, try restarting the router - sometimes a dual interruption NAT or blockage.

2. Google Cast (Chromecast) β for streaming from YouTube, Netflix and other apps
If you want to stream a specific video (e.g. YouTube, Netflix or Kodi) rather than the entire screen, use the Google Cast protocol. It works through apps that support the broadcast icon (e.g. Google Photos, Disney+, Twitch), the main condition is that the TV must be equipped with an integrated Chromecast (like Google TV or Android TV) or connected to an external Chromecast device.
Instructions:
- π± Open an app (like YouTube) on Redmi and find a video to watch.
- π Click on the broadcast icon (usually in the upper right corner of the player).
- πΊ Select your TV from the list of available devices.
- π¬ The video will start playing on TV, and the phone can be used for control (pause, volume).
β οΈ Attention: Xiaomi Redmi with shell MIUI Sometimes there is a problem when the icon Google Cast is not displayed in the applications. MIUI Solution: Update Google Play Services manually through the Play Market or clear the app cache in Settings β Annexes.

3.Broadcasting applications: best alternatives to standard methods
If the built-in functionality doesn't work, third-party apps come to the rescue. 7 popular utilities and chose the top-3 stability and speed of transmission:
| Annex | Protocol | Delay (MS) | Sound support | Features |
|---|---|---|---|---|
| ApowerMirror | Miracast/Wi-Fi Direct | 80β120 | Yes. | It works without root, supports control from the phone |
| Screen Mirroring (from Google) | Miracast | 60β100 | Yes. | Simple interface, but requires compatible TV |
| LetsView | Wi-Fi/P2P | 100β150 | Yes. | Supports screen recording, but there are ads |
For installation:
- Download one of the apps from the Play Market (links above).
- Run it and follow the instructions on the screen (usually allow access to Overlay over other applications in the security settings).
- Connect to the TV via Wi-Fi or over QR-code (if supported).
π‘
If the image on the TV is βlacking,β try to reduce the resolution in the application settings. For example, in ApowerMirror, select 720p instead of 1080p, which will reduce the load on the network.
4. DLNA/UPnP β for transferring media files without screen duplication
DLNA does not duplicate a smartphone screen, but broadcasts specific files (video, music, photos) to a TV. This is convenient if you do not need to show the phone interface, but only play a movie or slideshow. Most modern Smart TVs (including Samsung, LG, Sony Bravia) support DLNA.
How to set up on Xiaomi Redmi:
- Install a file manager with DLNA support, such as FX File Explorer or Solid Explorer.
- Open the application, find the file you want (for example, a movie in.mp4 or.mkv format).
- Click "Open with Help" and select the option to Play on DLNA-device.
- Choose your TV from the list.
β οΈ Attention: MIUI By default, it blocks the background of applications to save battery. If the broadcast is interrupted, add the file manager to exceptions: β Battery β Optimizing the battery β All applications β Find your manager and turn off optimization.

5 Problems and Solutions: Why Redmi's TV streaming doesn't work
Even with the right settings, the connection can break or not be installed.-5 causes and ways of eliminating them:
- π TV doesn't see phone: Check to see if Screen Mirroring is on TV (Samsung - Smart View, on TV) LG β Miracast.Reboot the router - sometimes DHCP does not give out correct IP-Redmi, turn off the address. VPN (It can block local connections).
- πΆ Lags and stuttering videos: Switch the router to 5 GHz (less interference). Close background apps on your phone (especially instant messengers and downloaders). Reduce the broadcast resolution in your app settings.
- π No audio: Check if the TV or app is turned off. In the broadcast settings, select Transmit audio (if you have one). For Google Cast, update the app that streams from (e.g. YouTube).
π‘
If nothing works, try resetting your network settings to Redmi: Settings β System β Reset β Reset your Wi-Fi, mobile network and Bluetooth settings. This will delete all the saved networks, but often solves connection problems.
6. Hidden MIUI features to improve broadcasting
Xiaomi adds hidden settings to MIUI that can improve wireless stability, such as Game Turbo mode in some firmware, which optimizes performance for streaming games, to activate it:
- Go to Settings β Special features β Game Turbo.
- Turn on the slider and add the app from which the broadcast is coming (for example, YouTube or ApowerMirror).
- Activate the option Improved graphics (if available).
Another lifehack is forced Miracast inclusion through the engineering menu (does not work on all models):
##6484##From the menu that opens, select the Miracast test and enable Force enable. This method can disrupt system stability - use at your own risk!
7. Alternative methods: when Wi-Fi is not an option
If wireless broadcasting fails fundamentally (for example, due to weak signal or protocol incompatibility), consider alternatives:
- π±USB-C β HDMI Adapter: Connect your phone to your TV via an adapter (e.g. Xiaomi) USB-C to HDMI). The downside is that the phone will discharge faster.
- πMHL (Mobile High-Definition Link: Older Redmi models (until 2019) MHL microUSB. You need a special cable.
- π‘Bluetooth + Smart TV: Some TVs (such as Samsung) QLED) Allows you to only transmit audio over Bluetooth and video via Bluetooth USB.
π‘
For games (such as Genshin Impact or Call of Duty Mobile), it is better to use USB-C β HDMI β input delay will be minimal (10-20 ms vs. 100+ ms over Wi-Fi).
