How to transfer video from Xiaomi phone to TV over Wi-Fi: all working ways

Wirelessly streaming video from Xiaomi to a big TV screen over Wi-Fi saves time and avoids wire confusion, but it’s not always clear which method to choose: built-in smartphone features, third-party apps or protocols like Miracast and DLNA. In this article, we’ll look at all the current ways, from standard MIUI tools to hidden features that aren’t written about in the official instructions.

The main problem is that users are not connected or soundless when broadcasting, and we tested each method on Samsung, LG, Sony Bravia and Xiaomi TVs, as well as on smartphones from Redmi Note 12 to Xiaomi 14 Ultra, and at the end of the article we have a compatibility table and answers to frequent questions that will help avoid typical errors.

1. the built-in Wireless Display (Miracast) function is the fastest way

Miracast is built into MIUI, allowing you to duplicate your smartphone screen onto your TV without any additional apps, ideal for streaming YouTube, TikTok or local 1080p files with minimal latency, and the main condition is that the TV must support Miracast (usually models no older than 2018).

To activate the broadcast:

• 📱 Open the Settings. → Connections and sharing → Wireless display on the smartphone Xiaomi.
• 🔍 Turn on device search and select your TV name from the list (e.g. Samsung) UE55 Xiaomi TV A2).
• 🔄 Confirm the connection on both devices. Some TVs will need to be entered PIN-code.
• 🎬 Start the video – it will automatically start broadcasting to the big screen.

An important nuance: when you duplicate the screen through Miracast, the video can be broadcast with black bars if the ratio of the sides of the smartphone and TV does not match. To stretch the picture, go to the broadcast settings on the phone and select the Fitting mode.

⚠️ Attention: On TVs LG From webOS below version 4.0 Miracast may not work. Update your TV firmware through Settings → General. → Update of the PO.

2.Using DLNA/UPnP for streaming media files

If you don't need to duplicate the entire screen, but only transfer video from the gallery, DLNA is a good protocol, it's built into most modern TVs and allows you to stream files directly from your phone, the advantage of the method is that there is no binding to a particular application, and the quality depends only on the source file (up to 4K).

Instructions for Xiaomi:

1. Make sure your phone and TV are connected to the same 5 GHz Wi-Fi network (Lags are possible at 2.4 GHz).
2. On the TV, activate it. DLNA-server (on the Network menu) → DLNA or media player).
3. On your smartphone, open the Gallery app, select a video, click Share → Transmit to TV.
4. In the list of devices, select your TV (e.g. Sony KD-55X80).

If you don’t have a built-in option, install BubbleUPnP from Google Play.It supports transcoding formats on the fly (for example, converts.mkv to.mp4 for TV compatibility).

3. Google Cast (Chromecast) – for streaming from apps

If your TV supports Google Cast (built-in or via Chromecast), you can stream videos directly from apps like YouTube, Netflix or Kodi, the main difference from Miracast is that it doesn’t transfer the phone screen, but only the content, which reduces battery load.

How to use:

• 📺 Make sure that the TV is enabled Google Cast (in network settings or through the Cast button on the remote).
• 🎥 Open the video in the supported app (for example, on YouTube click the broadcast icon in the upper right corner).
• 🔗 Select your TV from the list of devices.

The critical detail: the first setup of Google Cast requires Internet access, even if you're streaming local files via VLC or Plex. If Wi-Fi is disabled, use the mobile Internet on your phone to initialize the connection.

⚠️ Note: On Xiaomi phones with MIUI 14 and above, Google Cast background activity may be blocked due to battery optimization.To fix this, add the Google Play Services app to exceptions: Settings → Battery → Optimizing the battery → All applications → Google Play Services → No restrictions.

4. Smart Share service for Xiaomi TV

If you have a Xiaomi TV (Mi TV 4/5, Redmi Smart TV and later), use the built-in Smart Share feature.It is optimized for the Xiaomi ecosystem and supports:

• 📂 Video, photo and music broadcast without compression.
• 🔄 Two-way synchronization (can be controlled from the phone).
• 🔒 Secure connection via Wi-Fi Direct (no router required).

Connection algorithm:

1. On TV: Settings → Devices → Smart Share → Enable.
2. On the phone: Settings → Connections and Sharing → Smart Share.
3. Select the TV from the list and confirm the pairing.
4. Open the video in the gallery, click Share → Smart Share.

💡

If Smart Share doesn’t find the TV, restart both devices and turn on Bluetooth Detection on TV to speed up your search.

5. Third-party applications: when embedded methods do not work

If none of the above methods work (for example, an old TV without Miracast or DLNA), use universal applications:

• 📲 ApowerMirror – duplicates the screen with a delay ~200 ms, supports broadcast recording.
• 📺 LocalCast – streams local files from your phone, supports subtitles.
• 🎮 TeamViewer QuickSupport - a non-standard way for TV without Smart-features (requires a PC as an intermediary).

For ApowerMirror, the instructions are as follows:

1. Install the app on your phone and TV (if it’s Android TV).
2. Connect both devices to the same Wi-Fi network.
3. On your phone, select Connect to TV → Device Search.
4. Enter. PIN-code displayed on a TV screen.

Warning: Free versions of apps often limit resolution to 720p And they add watermarks. HD Premium subscriptions will be required (from 200) ₽/month).

6 Problem Solving: Video lags, no sound or connection breaks

Even with the right setup, you can have failures, and here are the typical errors and their solutions.

If the problem persists, check:

• 🔌 Are you using it? VPN on your phone (turn it off).
• 📶 Is the Wi-Fi channel overloaded (try changing the channel in the router settings to 6 or 11 for 2.4 GHz).
• 🔄 Is it blocking? MIUI background activity (check in Settings) → Permits → Auto-start).

💡

For stable 4K video broadcast, Wi-Fi speeds must be at least 30 Mbps. If the router does not support 5 GHz, use a cable TV connection to the network (via an Ethernet adapter).

7. Alternative methods: if Wi-Fi is not an option

In some cases, wireless transmission is not possible (for example, on very old TVs or in the absence of a router).

• 🔌 HDMI-adapter (Type-C/USB-C → HDMI): Connects the phone to the TV via cable. 4K@60fps, But requires an adapter with a DisplayPort chip (e.g. Xiaomi Mi). USB-C to HDMI). Price: from 1 500 ₽.
• 📁 USB-drive: Copy the video to a flash drive and play through the port USB The file format should be.mp4.mkv (check codec support in the TV manual).
• 🖥️ PC as an intermediary: Connect your phone and TV to your computer, use it VLC streaming over a local network.

Advice for owners of Xiaomi 13/14 series: If you use the adapter USB-C → HDMI, turn on the phone settings Out to the external display (Settings → Screen → Resolution of the external display).
