Connecting a smartphone screen to a Xiaomi TV via Wi-Fi opens up a lot of possibilities, from watching movies on the big screen to showing presentations or streaming games. However, many users face problems — the TV does not see the phone, then lags arise, then sound disappears. In this article, we will analyze all the current methods of wireless broadcasting, taking into account the peculiarities of the Xiaomi ecosystem, including hidden MIUI functions and the nuances of working with different TV models.
Xiaomi’s technology often supports unique protocols not available on other brands, such as PatchWall TVs that can use Miracast with enhanced quality settings, and MIUI 14+ smartphones that support live streaming via Quick Settings without installing third-party apps. But there are pitfalls: some TV models (such as Mi TV 4S 43) require developer mode pre-activation for stable operation.
If you've tried to connect before and you've failed, don't be quick to blame the technology. 80 percent of the time, the problem is with poor network settings (different router subnets), outdated firmware, or protocol conflicts (e.g., when your phone is trying to use Google Cast and your TV is waiting for Miracast), and we tested all the methods on the right devices (2023-2026) and identified those that work consistently.
1.Preparation: What to check before connecting
Before you start setting up, make sure your devices meet the minimum requirements, which will save time and save you from frustration.
Requirements for Xiaomi TV:
- 📺 The model supports Miracast or DLNA (All PatchWall TVs after 2018, including the Mi series TV A, Mi TV Q, Redmi Smart TV).
Requirements for the Xiaomi smartphone:
- 📱 MIUI 12 or later (older versions may not work on Google Cast).
- 🔋 Battery charge above 30% (at low charge, the system limits the performance of the Wi-Fi module).
- 🛠️ Developer mode enabled (optional, but will help with errors) Activated via Settings → The phone. → Version. MIUI (tap 7 times).
⚠️ Note: If your TV is connected to the network via cable (Ethernet) and your phone is connected via Wi-Fi, the broadcast may not work. Both devices must be on the same subnet, and you can check this in the router settings or through applications like Fing.
Method 1: Miracast – built-in protocol for Xiaomi
Miracast is a wireless broadcast standard that all modern Xiaomi TVs support, with its main advantage being minimal latency (ideal for gaming and video), and the downside being possible audio problems on some models.
How to connect:
- On TV: open Settings → Connection and Sharing → Wireless (Miracast)
- On your smartphone: lower the notification curtain and find the Broadcast button (or Wireless Display in MIUI 14+). If it is not, go to Settings → Connection and Sharing → Broadcast.
- Select your TV from the list. Confirm the connection on both devices.
⚠️ Note: Some Xiaomi TVs (e.g. Mi) TV P1) Miracast is hidden. To activate it, go to Settings. → All settings → System system → Developer mode and enable the option Enable wireless broadcast.

Challenges and solutions:
| Problem. | Reason. | Decision |
|---|---|---|
| TV can't see the phone | Different Wi-Fi subnets | Connect both devices to the same network (e.g. 2.4 GHz) |
| No sound is transmitted. | Miracast restrictions on some models | Use Bluetooth for sound or switch to Google Cast |
| Lags during broadcast | Weak Wi-Fi signal | Move your router closer or use 5 GHz |
💡
If the broadcast is interrupted, try turning off Wi-Fi power saving on your phone: Settings → Battery → Power saving mode → Disable for Wi-Fi.
3. Method 2: Google Cast (Chromecast) - for streaming video
If you only need to stream videos (like YouTube, Netflix, or Kodi), Google Cast is the best option. It works more stable than Miracast for media files, but does not support full-screen broadcasting (only individual applications).
How to set up:
- 📱 Make sure that the latest versions of apps (YouTube, Google Home, etc.) are installed on your phone.).
- 🖥️ On Xiaomi TV, turn on Google Cast in Settings → Connection and sharing → Google Cast.
- 🎬 In the app (like YouTube), click the broadcast icon and select your TV.
Supported annexes:
- 🎥 YouTube, Netflix, Disney+ (Official support for Cast).
- 🎵 Spotify, Yandex Music (sound only).
- 📁 Gallery, Google Photos (broadcast photo / video).
⚠️ Note: Xiaomi TVs with PatchWall firmware older than 2021 may require manual installation of Google Cast services via Settings → Annexes → Install system applications.

4. Method 3: AirPlay is for iPhone owners (but Xiaomi supports it too!)
Few people know, but Xiaomi’s PatchWall TVs (starting in 2020) support AirPlay, Apple’s protocol, which means you can stream the screen not only from your iPhone, but also from Xiaomi through special apps.
How to connect with Xiaomi:
- On TV: Settings → Connection and Sharing → AirPlay → Enable the feature.
- On your phone: install the ApowerMirror or AirScreen app (available on Google Play).
- In the app, select your TV and confirm the connection.
Advantages of AirPlay on Xiaomi:
- 🎮 Minimal delays (better than Miracast for games).
- 🔊 Support for sound without additional settings.
- 📱 It works even on older smartphones (MIUI 11+).
⚠️ Note: On some TV models (Mi) TV 4X, Redmi TV 70") AirPlay can be disabled by default. To activate it, go to Settings → All settings → System system → Developer mode → Enable AirPlay.
5. Method 4: Broadcast applications (if embedded methods do not work)
If standard protocols (Miracast, Google Cast) fail to work, third-party apps will come to the rescue, often offering additional features such as screen recording or high-resolution broadcasting.
Top.-3 tested applications:
| Annex | Pluses | Cons |
|---|---|---|
| ApowerMirror | Supports 1080p, low latency | Free version with watermarks |
| TeamViewer QuickSupport | It works over the Internet (not necessarily one network). | Registration is required |
| Screen Mirroring (by Google) | Simple interface, no advertising | Sometimes she loses her connection. |
How to use (as an example of ApowerMirror):
- Install the app on your phone and TV (if you have Google Play on TV).
- Run ApowerMirror on both devices.
- On the phone, select Mirroring → Connect to TV.
- Confirm the connection on the TV.
⚠️ Note: When using third-party apps, turn off battery optimization for them in your phone settings (Settings) → Annexes → Permits → Autostart and background activity. Otherwise, the connection will break.
💡
The app side is the best choice if you have an old Xiaomi TV (before 2019) or custom firmware.They bypass the limitations of embedded protocols, but may require more resources.
Method 5: DLNA – for broadcasting media files without a screen
If you don't have to duplicate the entire screen, but just transfer photos, videos or music, DLNA is the easiest way. It works on all Xiaomi TVs and doesn't require complex settings.
How to set up:
- 📱 On your phone: install BubbleUPnP or LocalCast.
- 🖥️ On TV: turn it on DLNA In Settings → Network → DLNA.
- 🎵 In the app on your phone, select a file and send it to the TV.
Advantages of DLNA:
- 📁 Supports playlists and folders.
- 🔄 It does not require a connection to a single network (works through local Wi-Fi).
- 🎧 You can stream the sound on the TV and leave the video on the phone.
⚠️ Attention: DLNA It doesn't broadcast a screen, it only broadcasts media (4K) Lags may occur, and it is better to use Google Cast or Miracast.
7. Solving common mistakes
Even with the right setup, there can be problems, and here are the most common mistakes and solutions:
1. The TV can't see the phone:
- 🔌 Restart your router – sometimes DHCP slander IP-address.
- 📶 Check that both devices are connected to the same network (not the guest network!).
- 🔄 On your phone, turn off Adaptive Wi-Fi in Settings → Wi-Fi → Additionally.
2. Lags and stuttering video:
- 📶 Switch to 5 GHz (if the router supports).
- 🎮 Reduce the broadcast resolution in Miracast settings (e.g., with 1080p on 720p).
- 🔋 Close the background apps on your phone (especially instant messengers and games).
No sound:
- 🔊 Check if the sound on the TV or phone is off.
- 🎧 Connect your headphones to your TV via Bluetooth and check if the sound is coming through them.
- 🔄 Reconnect by selecting a different protocol (e.g. from Miracast to Google Cast).
