Modern Xiaomi TVs (Mi TV A Pro, Mi TV Q2, Redmi Smart TV, and others) support many ways to wirelessly and wiredly connect to smartphones, which allows you to stream YouTube videos to the big screen, play mobile games with a gamepad or duplicate desktop for presentations, but not all users know how to configure pairing correctly โ especially if the TV does not detect the phone or the connection is constantly broken.
In this article, we will break down all the current ways of connecting (including hidden MIUI and Google Cast features), compare them in speed and stability, and give a checklist to eliminate typical errors.
1. Preparation of TV and telephone for pairing
Before you connect devices, make sure they meet the minimum requirements:
- ๐บ Xiaomi TV: models with Android TV 9.0 and higher (e.g. Mi) TV 4S 55", Redmi Smart TV X55). For older versions (until 2019) may require a firmware update.
- ๐ฑ Smartphone: Android 8.0+ (for Miracast or iOS 12+ (On the iPhone, only mirroring through third-party apps is available.
- ๐ Shared Wi-Fi network: Both devices must be connected to the same access point (for Google Cast and Google Cast). DLNA). Wi-Fi Direct does not require a network.
If your TV is released before 2020 (for example, Mi). TV 4A), Check the firmware version in the Settings menu โ The Miracast needs firmware at least as low as the TV. MIUI TV 1.6.50 You can update it via Settings โ Update the software or manually using USB-storage.
๐ก
If the TV doesnโt see the phone in the list of available devices, try rebooting both devices and disabling the VPN on the smartphone โ some apps block local connections.
Method 2: Wireless screen duplication via Miracast
Miracast is a wireless image transfer standard built into most Xiaomi TVs that allows you to duplicate the screen of your smartphone without delay (latency ~30 ms), which is ideal for games and video, but requires support for technology on both devices.
How to turn Miracast on your TV:
- Open Settings โ Connections and Sharing โ Wireless display.
- Activate the Miracast switch (in some models, the item is called Screen Mirroring).
- Select Connect to the device (if you need input) PIN-Use the code, 0000 or 1234).
On a smartphone (for example, Xiaomi Redmi Note 12):
- Go to Settings โ Connections and Sharing โ Screen Transfer.
- Select your TV from the list (the name will appear as MI-TV-[model]).
- Confirm the pairing on both devices.
If the image slows down, reduce the resolution in Miracast settings on your phone (image quality option). For games, fast display mode is recommended, and for video - high quality.

Method 2: Broadcasting via Google Cast (Chromecast)
Google Cast is an alternative to Miracast, which works over the Internet and allows you to stream content from apps (YouTube, Netflix, Google Photos) without duplication of the entire screen, the main advantage is less load on the phone processor and the ability to continue to use the smartphone while streaming.
Instructions for setting:
- ๐ Make sure that the Google Play Services app is installed on your TV (check Settings). โ If it is not available, update the firmware.
- ๐ฑ On your phone, open an app that supports Cast (like YouTube) and tap the broadcast icon (๐บ).
- ๐ Select your Xiaomi TV from the list. If it is not, check if Google Cast is enabled in the settings of the TV (Settings) โ Network and access โ Cast).
To stream local files (video, photos) use the Google Photos app or Files by Google. They also have a Cast button, but the transfer rate will depend on the power of the TV.
4. Method 3: Wired connection through HDMI (MHL/Slimport)
If wireless methods are unstable or require minimal latency (e.g. for streaming games), use the HDMI-It's going to take a connection:
- ๐ Adapter: For USB-C: adapter USB-C โ HDMI (for example, Xiaomi USB-C to HDMI). For Micro-USB: Adapter MHL Slimport (check compatibility with your phone model!).
- ๐บ HDMI-cable 1.4 or 2.0 support 4K@60Hz).
Step-by-step:
- Connect the adapter to the phone and then connect it to the TV with an HDMI cable.
- On the TV, select the source of the HDMI signal (Source button on the remote).
- On the phone, you may need to enable HDMI Mode in the notification curtain or in the screen settings.
If the image does not appear:
- Check if your phone supports HDMI output (some Redmi budget models may not have this feature).
- Try another cable or adapter โ cheap Chinese adapters often donโt support 4K.
- Update the phoneโs firmware (older versions of MIUI could have HDMI-output bugs).
What if your phone doesnโt display HDMI sound?
5. Method 4: Wi-Fi Direct Connection (for older models)
Wi-Fi Direct is a direct connection technology for devices without a router, which is useful if you don't have Internet access or the TV doesn't support Miracast, but the data rate is lower, and there may be delays when watching videos.
How to set up Wi-Fi Direct:
- On TV: Settings โ Network and Internet โ Wi-Fi Direct โ turn on the function and wait for the device to be searched.
- On the phone: Settings โ Wi-Fi โ Wi-Fi Direct (or Settings โ Connections โ Wi-Fi Direct on Samsung).
- Select the TV from the list and confirm the pairing (PIN-code usually 12345678 or 00000000).
Once connected, you can transfer files or use the TV as an external screen through apps like ApowerMirror or TeamViewer QuickSupport, but you will need additional software to duplicate the screen โ you canโt do that with standard Android tools.
๐ก
Wi-Fi Direct consumes more power than Miracast or Google Cast. If the phone runs out quickly, plug it into charging or use a wired method.
Method 5: Bluetooth interface for sound and control
If you only need to transmit sound (for example, to listen to music through the speakers of the TV) or use the phone as a remote, Bluetooth is suitable.
- ๐ต Listen to music via Spotify or YouTube Music.
- ๐ฎ Using your phone as a gamepad (via apps like Octopus).
- ๐ฑ Control your TV through voice commands (if supported by Google Assistant).
How to connect:
- On TV: Settings โ Devices โ Bluetooth โ turn on search.
- On your phone: Settings โ Bluetooth โ select a Xiaomi TV from the list.
- Confirm the pairing (you may need to enter the code 0000).
To transmit the sound:
- In the phone settings, select Settings โ Sound โ Sound Out โ [Name of your TV].
- Start playing music - the sound will go through the TV speakers.

If the Bluetooth pairing is constantly breaking, try turning off the Adaptive Bluetooth feature in your phone settings (in some MIUI firmware, it can cause conflicts).
7. Solving Connection Problems
If the TV canโt see the phone or the connection is unstable, check the following points:
| Problem. | Possible cause | Decision |
|---|---|---|
| The TV is not displayed in the list of devices | Miracast or Wi-Fi Direct is disabled | Turn on the feature in the TV settings and restart both devices |
| Image lagging or slowing down | Weak Wi-Fi signal or overloading of the TV processor | Reduce the broadcast resolution or use HDMI |
| No sound when connected | The wrong audio source on the TV | Select HDMI or Bluetooth in the audio settings |
| The connection is broken in 1-2 minutes | Active energy saving mode on the phone | Turn off battery optimization for Miracast or Google Cast apps |
| Google Cast doesnโt work in apps | An outdated version of Google Play Services | Update services through Google Play or manually |
If neither of these methods works, check to see if the antivirus or VPN connection on your phone is blocking, and make sure that the TV is not activated with child mode or guest access, which may limit the pairing functionality.

- ๐ฎ For games: HDMI (Minimum latency) or Miracast in Quick display mode.
- ๐ฌ For video: Google Cast (less phone load) or HDMI (for 4K HDR).
- ๐ For music: Bluetooth or Wi-Fi Direct (if you need a high bitrate).
- ๐ฑ For screen duplication: Miracast (if the phone supports) or USB-C โ HDMI.
Xiaomiโs 2023-2026 TVs (Mi TV S Pro and Redmi Smart TV Max series) have Wi-Fi 6 support, which greatly improves Miracast and Google Cast stability. If your router supports this standard, update your TV firmware to activate the feature.
For iPhone owners, the only reliable way โ HDMI-Adapter (e.g. Lightning Digital) AV Adapter) or applications like ApowerMirror (delayed) ~100ms.AirPlay on Xiaomi TVs is not supported without additional devices (e.g. Apple) TV).
