Wi-Fi video transmission is convenient, fast and requires no additional cables. However, not all methods are equally effective: somewhere you need special applications, and somewhere there are enough built-in smartphone functions.

We'll focus on the typical problems of why the image is lagging, the sound is late, or the broadcast is suddenly interrupted, and at the end of the article we'll talk about the FAQ, which answers to frequent questions and the table of device compatibility.

1. Method: Miracast - live screen broadcast without applications

Miracast is a wireless screen standard that is supported by almost all modern Xiaomi TVs and smartphones (starting with MIUI 9), the main advantage of which is that you do not need to install additional software – everything works through the built-in settings.

How does it work? Your phone duplicates its screen to the TV in real time, and it's convenient for watching movies from any player (including MX Player, VLC), games, or even presentations.

• 📶 Latency can be as high as 0.5-1 seconds, critical for games, but not noticeable when watching movies.
• 🔋 Battery consumption increases by 20 to 30 percent due to active data transfer.
• 📺 The TV and phone must be on the same Wi-Fi network (or connected directly via Wi-Fi Direct).

To include Miracast on Xiaomi:

1. Open Settings → Connections and Sharing → Screen Transfer.
2. Select your TV from the list of available devices (if not, check if Miracast is enabled in your TV settings).
3. Confirm the connection on both devices.

Important: on Samsung TVs, this mode may be called Screen Mirroring, on LG it may be called Wireless Display, and on Xiaomi TV it may be called Wireless Display. If your TV doesn't support Miracast, try alternative ways in the following sections.

2. Method: DLNA/UPnP – streaming movies through a local network

DLNA (Digital Living Network Alliance) is a protocol for sharing media between devices on a single network, and unlike Miracast, it doesn't transfer a phone screen, but a specific file (film, music, photo) that means:

• ✅ No sound/image delay.
• ✅ You can continue to use your phone while watching.
• ❌ Not all video formats are supported (e.g..mkv may not play on older TVs).

Xiaomi smartphones for DLNA use the built-in Mi File Explorer or Gallery app.

1. Connect your phone and TV to the same Wi-Fi network.
2. Open the Explorer, find the right movie and tap on it.
3. In the playback menu, select Replay on → [name of your TV].

If the built-in tools don’t work, install a third-party app like BubbleUPnP or LocalCast. They support more formats and allow you to stream even from YouTube or Twitch.

3. Method: Xiaomi Smart Share - a proprietary solution for the Mi ecosystem

Xiaomi Smart Share is a proprietary technology from Xiaomi that combines Miracast and DLNA capabilities into one interface, it runs faster than standard protocols and is optimized for Mi ecosystem devices (Mi TVs, Mi Soundbar speakers, etc.).

Advantages of Smart Share:

• 🚀 Instant connection to Xiaomi devices (without manual search on the network).
• 🎵 Support for audio streams (you can stream music to the column and video to TV at the same time).
• 📱 It works even with a locked screen (if the option is enabled in the settings).

How to use:

1. Activate Smart Share in Settings → Connections and Sharing → Smart Share.
2. Select a file in the Gallery or Explorer and tap Share → Smart Share.
3. Select the target device (television or column).

💡

If Smart Share doesn’t find the TV, check if the “Mi Home” mode is enabled in the TV settings (on Xiaomi TV: Settings → Smart Home → Mi Home).

Limitation: Smart Share may not work with other brands of TVs (such as Samsung or LG).In this case, use DLNA or Google Cast.

4. Method: Google Cast (Chromecast) – for YouTube, Netflix and browser

If you often watch content from YouTube, Netflix, Kinopoisk, or even just Chrome, Google Cast is the perfect protocol for sending videos directly from the app to the TV without broadcasting the entire screen.

How it works for Xiaomi:

1. Make sure your TV has Google Home (for Android TV) installed or Chromecast support built in.
2. Open the video to YouTube or another supported app.
3. Slip on the Cast icon (usually in the upper right corner) and select your TV.

List of apps that support Google Cast:

• 🎬 YouTube, Netflix, Disney+
• 🎵 Spotify, Google Music
• 🌐 Chrome (broadcasting tabs)

The downside is that not all local video files can be streamed via Cast, and it’s better to use DLNA or LocalCast.

5. Method: Third-party applications – LocalCast, AllCast, VLC

If the built-in methods don't work (for example, an old-model TV or you need support for rare formats), third-party apps will come to the rescue.-3 test-driven:

Example of LocalCast settings:

1. Install the app from Google Play.
2. Open the file in LocalCast and select the target device (TV).
3. If necessary, set up subtitles or bitrates in the broadcast menu.

VLC is convenient for playing files from NAS or network folders, to stream video through it:

1. In VLC, open Local Network → UPnP.
2. Select the file and tap Replay on → [your TV].

💡

For stable broadcasting through third-party apps, turn off energy saving for them in MIUI settings: Settings → Battery → Battery Optimization → Select the application → No restrictions.
