Broadcasting video from your phone to a large screen of a Xiaomi TV via Wi-Fi is a convenient way to enjoy your favorite movies, commercials or streams without unnecessary wires. However, not all users know that there are several technologies for this, from standard Miracast to branded solutions like Google Cast or DLNA. Each method has its own nuances – from support for formats to image delay – and the choice depends on both the model of your TV and your smartphone.
In this article, we will discuss all the current methods of wireless video transmission on Xiaomi TV (including Mi TV 4A/4S/5/5X/Q1/Q2 models and others), as well as consider the typical problems - why the image slows down, why there is no sound or why the TV does not see the phone at all.
1.Preparation: What to check before broadcasting
Before you try to connect your phone to your TV, make sure that both devices meet the minimum requirements:
- 📱 Smartphone: Android 5.0+ (for Miracast or iOS 12+ (AirPlay, with Wi-Fi 5 GHz support (recommended for stable broadcasting).
- 📺 Xiaomi TV: models with Miracast (most after 2018) or Google Cast (Q and Pro series). → Connections → Wireless projection.
- 🌐 Wi-Fi network: both devices must be connected to the same network (preferably 5 GHz). VPN.
Pay special attention to TV firmware. Outdated software versions (below MIUI TV 3.0) may not support modern broadcast protocols. Update TV through Settings → About TV → System Update.
⚠️ Note: If your Xiaomi TV is released before 2017 (e.g. Mi) TV 3), it may not support Miracast over Wi-Fi. DLNA external adapters (e.g. Xiaomi Mi) TV Stick).
Method 1: Miracast is the standard protocol for Android
Miracast is a universal wireless broadcast standard built into most of today’s Android smartphones and Xiaomi TVs, which allows you to duplicate your phone screen on TV with minimal latency (ideal for games or videos).
To activate Miracast:
- On TV: Open Settings → Connections → Wireless projection (Miracast) and select Enable.
- On your smartphone: go to Settings → Connections → Screen Broadcast (on Xiaomi – Quick Settings → Projection).
- In the list of available devices, select your Xiaomi TV (the name will contain a model, for example, MiTV-Q1-1234).
Once connected, the phone screen is fully duplicated on TV. To stop the broadcast, pull down the notification panel and press Turn off projection.
Both devices are connected to the same Wi-Fi network (5 GHz)
Miracast mode is on on the TV.
Power saving mode on the phone is off
Distance between devices not more than 5 meters-->
⚠️ Note: On some Xiaomi models TV (Like Mi. TV 4A 32") Miracast is hidden. To activate it, go to Settings. → All settings → Additionally. → Wireless projection.
3. Method 2: Google Cast (Chromecast) – for streaming from apps
If you don’t need to duplicate the entire screen, but only stream videos from a specific app (like YouTube, Netflix or Kodi), use Google Cast.This protocol is built into Xiaomi’s Q and Pro series TVs (starting in 2019).
Instructions:
- 📱 On your smartphone, open an app (like YouTube) and find the Cast icon (usually in the upper right corner).
- 📺 In the list of devices, select your Xiaomi TV (the name will contain MiTV-[model]).
- 🎬 Run the video - it will start broadcasting on TV, and the phone will remain a control panel.
The advantage of Google Cast over Miracast is a lower load on the phone (video streams directly from the Internet to TV) and support for 4K HDR on compatible models.
| Function | Miracast | Google Cast |
|---|---|---|
| Screen duplication | ✅ Yes. | ❌ No (only from the appendices) |
| Delay (lag) | ~50-100 ms | ~20-50 ms |
| 4K support | ❌ No (max. 1080p) | ✅ Yes, on Mi. TV Q2 newer) |
| Working without Wi-Fi | ✅ Yes (direct connection) | ❌ No (network needed) |
💡
If the video is slowing down when streaming via Google Cast, try setting the router to set the 5 GHz channel manually (for example, 36 or 48) and disable the Smart Connect function (it automatically switches devices between 2.4 and 5 GHz).
4. Method 3: DLNA - for local files
DLNA is a protocol for transmitting media files (video, photos, music) over a local network, it doesn't duplicate screens, it only plays files from phone to TV, it's suitable for movies downloaded to a device.
How to use:
- On TV: Open the Media Player or Gallery app and select DLNA.
- On a smartphone: install a DLNA server application (e.g. BubbleUPnP or LocalCast).
- In the app, select a file to broadcast and specify the Xiaomi TV as the output device.
DLNA It supports most formats (including: MKV, MP4, AVI), but may not play back files from DTS-In this case, use Miracast or convert the audio track.

5. Method 4: AirPlay for iPhone (on Xiaomi TVs with MIUI TV 4.0+)
iPhone or iPad owners can stream video to Xiaomi TV via AirPlay, but only if the TV is running MIUI TV 4.0 or later (models of 2020 and later).

- 🔌 Router: Turn off the function AP Isolation (it blocks device interaction on the network) Also check that Multicast is enabled (required for the device to be connected to the network). Miracast/DLNA).
- 📶 Wi-Fi signal: If the signal strength is below 70%, move the router closer to the TV or use the Mesh system.
- 🔄 Ports: Ports should be open on the router 1900/TCP (DLNA), 7000/TCP (Miracast and 5353/UDP (AirPlay).
If the image slows down, try:
- 🎮 Reduce the broadcast resolution in Miracast settings (select 720p instead 1080p).
- 📡 Switch from 5 GHz to 2.4 GHz (if the distance between devices is more than 10 meters).
- 🔋 Disable background apps on your phone (they consume processor resources).
