Broadcasting your smartphone screen to Xiaomiโs big screen opens up new possibilities, from watching high-resolution movies to showing presentations or streaming games. However, not everyone knows that the way you connect depends not only on the phone model (Redmi, POCO, Mi), but also on the TV generation (Mi TV series A, P, Q, S or ES). In this article, we will analyze all current methods โ from wireless protocols to wired adapters โ and also reveal the nuances of settings that the manufacturer often does not.
The main problem that users face is the incompatibility of protocol versions or the lack of support for certain functions on older models. For example, Xiaomi TVs 2018-2019 release may not support Miracast through embedded software, and iPhone smartphones require additional adapters for wired connection. We tested all methods on current firmware (MIUI 14/15 and TV OS 3.0+) and compiled checklists for each option.
1. Wireless broadcast on Miracast (Screen Mirroring)
Miracast is the most versatile way to duplicate a wireless screen, but it only works between devices that support this standard. All Xiaomi TVs since Mi TV 4A (2018) and Android 5.0+ smartphones are theoretically compatible, but in practice, there are often connection problems due to different versions of the protocol.
To activate the broadcast:
- ๐ฑ On your smartphone: open Settings โ Connections and sharing โ Screen broadcast (on Xiaomi/Redmi) or settings โ Screen. โ Wireless broadcast (on other Android devices).
- ๐บ On TV: Go to Settings โ Connection and sharing โ Wireless display and enable the option.
- ๐ In the list of available devices on your phone, select the name of your TV (e.g. MiTV-XXXXX).
If the TV is not on the list, check:
- ๐ Is the TV firmware updated (updated version โ TV OS 3.0+).
- ๐ถ The phone and TV are connected to the same Wi-Fi network (even though Miracast doesnโt require internet, some Xiaomi models use the network to detect the network).
- ๐ง In the settings of the TV developer, the option Debugging over Wi-Fi is enabled (path: Settings) โ On TV. โ POS version โ Press "Version" 5 times").
๐ก
If the broadcast is interrupted or slowed down, reduce the screen resolution on the phone to 720p in Miracast settings (if such an option is available).
โ ๏ธ Attention: On the TVs Xiaomi Mi TV 4S (2019) and older may require manual Miracast mode activation via the engineering menu. โ Settings โ All settings โ General. โ Developer mode โ Turn on Miracast.
2.Using Google Cast (Chromecast) for Android and iOS
If your Xiaomi TV supports Google Cast (built into models with TV OS 2.0+), you can stream the screen through apps that support this technology (YouTube, Netflix, Google Photos, etc.). Full screen duplication (like Miracast) is only available on Android devices through the screen broadcast feature.
Instructions for Android:
- Make sure your phone and TV are connected to the same Wi-Fi network.
- On your TV, open the Google Play Movies and TV or YouTube app and click the broadcast icon (๐ค).
- On the phone in the notification bar, find the Broadcast (or Cast) button and select your TV.
For iPhone, full screen broadcasting is not possible without additional devices, but you can transfer media files through the apps:
- ๐ฌ YouTube: Click the broadcast icon in the player.
- ๐ท Google Photos: Select a photo/video โ broadcast โ Choose a TV.
- ๐ต Spotify: in the player, click Devices available โ Choose Mi. TV.
| The device | Supported applications | Full screen broadcast |
|---|---|---|
| Android (MIUI 12+) | YouTube, Netflix, Google Photos, Chrome | Yes (via Screencast) |
| iPhone (iOS 14+) | YouTube, Google Photos, Spotify | No (media files only) |
| MacBook/Windows | Chrome (Google Cast extension) | Yes (browser tabs only) |
3. Wired connection via HDMI or USB-C
For minimal latency and maximum image quality (such as games or videos in 4K HDR), it is better to use a wired connection. Modern Xiaomi smartphones (starting with the Redmi Note 10 Pro and Mi 11) support video output via a USB-C port using a USB-C โ HDMI adapter.
What you need:
- ๐ adapter USB-C to HDMI (Smartphones with DisplayPort Alt Mode).
- ๐บ Cable HDMI (version 2.0 for 4K@60Hz).
- โก Power supply for the phone (broadcast drains the battery faster).
Important: not all USB-C โ HDMI adapters work with Xiaomi smartphones. Check compatibility on the manufacturerโs website โ the adapter must support the DisplayPort Alt Mode protocol (for example, models from Anker or Baseus).
Step-by-step:
- Connect the adapter to the USB-C port of the phone.
- Connect the adapter to the TV with an HDMI cable (use the HDMI 2.0 port for 4K).
- On the TV, select the source of the HDMI signal (Source button on the remote).
- The phone may need to confirm trust in the connected device (a notification will appear).

โ ๏ธ Note: Xiaomi smartphones with MediaTek processors (such as Redmi Note 12) may not work sound through HDMI. Solution: Use a separate audio output (Bluetooth or 3.5mm jack).
4. Connect via Mi Home (for the Xiaomi ecosystem)
If you have Xiaomi smart devices (Mi Smart Speaker, Yeelight, etc.), you can use the Mi Home app to broadcast the screen. This method only works within the ecosystem and requires:
- ๐ฑ Smartphone with Mi Home installed (version 6.0)+).
- ๐บ Xiaomi TV with a tied Mi Account.
- ๐ Stable Internet connection (data is transmitted through Xiaomi servers).
How to set up:
- Open Mi Home and make sure your phone and TV are tied to the same account.
- Go to the Devices section โ [Your TV] โ Screen broadcasting.
- Click Start broadcast and confirm the connection on the TV.
Advantages of this method:
- โ It works even if your phone and TV are on different Wi-Fi networks (via the Xiaomi cloud).
- โ Supports control of the TV from the phone (the remote in the application).
Disadvantages:
- โ Image delay up to 1-2 seconds.
- โ Requires authorization in your Mi Account (not suitable for guest devices).

5. Alternative methods: DLNA and third-party applications
If standard methods don't work, you can use DLNA or third-party applications like ApowerMirror or TeamViewer QuickSupport, which are suitable for streaming media or remote management, but have limitations:
DLNA (for photo/video/music):
- ๐ On the phone: install the application server DLNA (For example, BubbleUPnP).
- ๐บ On TV: Open the Media Player โ DLNA and select the phone in the list of devices.
Streaming through apps:
- ๐ฅ๏ธ ApowerMirror: Supports screen broadcasting and phone control (requires installation on both devices).
- ๐ฎ Steam Link: for streaming games from PC to TV via phone as an intermediary.
| Method | Delay. | Quality. | Internet is required |
|---|---|---|---|
| DLNA | No (media only) | Original | No. |
| ApowerMirror | 0.5-1 s | Up to 1080p. | Yeah (Wi-Fi) |
| TeamViewer | 1-3 seconds | Up to 720p. | Yes. |
6. Problem Solving: Why is the broadcast not working?
If the screen is not duplicated or the broadcast is interrupted, check the following points:
Common problems:
- ๐ No image on the HDMI: Try another cable or port on your TV. Some Xiaomi models require the use of a port HDMI ARC mobile-connection.
- ๐ถ Miracast does not find the TV: turn off the phone power saving mode and VPN, Then restart both devices.
- ๐ No sound: check if the sound is turned off in the settings HDMI on the TV (Settings) โ Sound. โ Exit HDMI).
Problems with specific models:
- ๐ฑ Xiaomi Mi 10/11: when connected USB-C permission to transfer video in the developer settings may be required (Debugging by USB โ Allow video transmission).
- ๐บ Mi TV Q1/Q2: for wireless broadcasting, it is necessary to disable the function AI Master for Picture in Image Settings.
- ๐ iPhone: full screen broadcast is only possible through the Lightning adapter โ HDMI (For example, the original Apple Digital AV Adapter).
๐ก
If the stream is working but the image is slowing down, reduce the screen resolution of the phone to 720p or turn off background apps. On Xiaomi TVs, it also helps to turn on the Game mode (Settings โ Picture โ Image Mode โ Game).
Comparison of all methods: which one to choose?
The choice of method depends on your tasks:
- ๐ฎ For games: wired connection by HDMI (minimum delay).
- ๐ฌ For movies: Google Cast (if supported) or Miracast.
- ๐ For presentations: Miracast or USB-C โ HDMI (stability is more important than quality).
- ๐ฑ For iPhone: Lightning adapter โ HDMI AirPlay (if the TV supports the TV).
