1. Connection via Miracast: Duplication of the phone screen on TV

Miracast is a wireless image and sound transmission standard supported by most of Xiaomi’s current Android smartphones and TVs, with its main advantage being low latency (around 50 to 100 milliseconds), which is critical for gaming or watching video, but there are also downsides: high phone power consumption and possible artifacts with a weak Wi-Fi signal.

To connect via Miracast:

1. Make sure your phone and TV are connected to the same Wi-Fi network (or use Wi-Fi Direct if you don’t have a router).
2. On TV: Go to Settings → Connection and sharing → Wireless display (or Miracast depending on model).
3. On the phone: open Settings → Connected devices → Screen transmission (on MIUI The path may be different: Settings → Screen. → Wireless display).
4. Select your TV from the list of available devices.

If the TV is not on the list, check:

• 🔄 Update the TV firmware to the latest version (relevant for models older than 2020).
• 📶 Reconnect both devices to Wi-Fi or reboot the router.
• 🔋 Turn off the power saving mode on your phone – it can block Miracast.

⚠️ Note: Some Xiaomi models (e.g. Mi) TV Stick) Miracast only works in 5 GHz mode. If your router does not support this frequency, use alternative ways to connect.

To reduce delays in broadcasting:

💡

If the image on TV “breaks” or slows down, try to reduce the resolution of the broadcast to 720p. This will reduce the load on the phone’s processor and stabilize the flow.

2. Mi Share: Fast transfer of files and media to TV

Mi Share is Xiaomi’s proprietary technology, similar to Apple’s AirDrop, which allows files to be transferred between Xiaomi devices (including TVs) without an internet connection using Wi-Fi Direct or Bluetooth, with the main advantage of speed (up to 10MB/s) and no loss of quality when transferring photos or videos.

How to use Mi Share:

1. On TV: Turn on Mi Share in the Settings menu → Connection and sharing → Mi Share.
2. On the phone: open the file manager (Files or Explorer), select the desired files and click Send → Mi Share.
3. Select your TV from the list of devices and confirm the transmission on both screens.

Supported file formats:

• 📷 Photo Photo: JPEG, PNG, HEIF (model MIUI TV 3.0+).
• 🎬 Video: MP4, MKV, MOV (max. authorization 4K file size up to 4 GB).
• 🎵 Music: MP3, FLAC, AAC.
• 📄 Documents: PDF, TXT, DOCX (Opening through the built-in viewer).

⚠️ Note: If file transfers are interrupted, check if the antivirus on your phone (e.g. Avast or 360 Security) is blocking the transfer.

The difference between Mi Share and Miracast:

💡

Mi Share is ideal for photos and videos, but it doesn’t replace Miracast if you need to duplicate your phone screen (for example, for presentations or games).

3. DLNA: broadcasting media without screen duplication

DLNA (Digital Living Network Alliance is a protocol for transmitting media over a local network, which, unlike Miracast, does not duplicate the screen of the phone, but streams only selected files (movies, music, photos), which reduces the load on the phone and reduces latency.

How to set up DLNA on Xiaomi TV:

1. On TV: turn it on DLNA Settings menu → Network services → DLNA.
2. Install a media server application on your phone, such as BubbleUPnP (for power users), LocalCast (a simple interface), VLC (built-in DLNA).

In the app, select a file to broadcast and specify your TV as the output device.

The advantages of DLNA over Miracast:

• 📉 Less phone load (no need to render the screen in real time).
• 🎵 Support for background playback (you can turn off the phone screen).
• 📂 The ability to create a playlist from several files.

Disadvantages:

• ❌ No screen transfer (only individual files).
• ❌ Not all video formats are supported (for example, the video formats are not supported, AVI may not reproduce).
• ❌ Dependence on third-party applications (in MIUI no-built-in DLNA-client).

4. AirPlay on Xiaomi TV: Does it work and how to set up?

Many users are surprised to learn that Xiaomi TV It supports AirPlay, Apple's wireless media technology, made possible by the protocol's built-in support for Android TVs. TV 9.0+ (Like Mi. TV Q1/Q2 or Redmi Smart TV X2022). But there are nuances:

What works through AirPlay on Xiaomi TV:

• 🎬 Broadcasting videos from YouTube, Netflix, Apple TV+.
