Why Connect Xiaomi Phone to a Wi-Fi TV
Wirelessly streaming your smartphone screen to Xiaomi’s big TV screen opens up a lot of possibilities, from watching high-resolution movies to showing photos at family nights. But many users face problems: the image slows down, the sound disappears, and the connection is constantly broken. In this article, we will analyze all the current ways of connecting (including hidden MIUI functions), optimize settings for stable operation and solve typical errors.
Xiaomi TVs (Mi TV A2, P1, Q2, etc.) have several wireless protocols: Miracast, DLNA, and even Apple AirPlay (on new models), but the connection algorithm depends not only on the TV model, but also on the MIUI version on the smartphone. For example, on the Redmi Note 12 with MIUI 14, the path to screen settings is different from the Xiaomi 13 Ultra with HyperOS.
Important: If your TV is released before 2020 (e.g. Mi TV 4S 55), some features may not be available. You can check for support for a specific protocol in the Settings menu → Connections → Wireless projection.
Method 1: Miracast – Direct connection without router
Miracast allows you to stream your smartphone screen to your TV without a router intermediary, ideal for travel or if you don't have a home Wi-Fi network.
- 📶 It only works at a distance of 10 meters (in ideal conditions).
- 🔋 Increased battery consumption of the smartphone (up to) 15-20% hourly).
- 🎮 Image delay ~50-100 MS (not suitable for games).
To activate Miracast on Xiaomi TV:
- Open Settings → Connections → Wireless projection.
- Select Miracast (or Wi-Fi Direct on older models).
- Run a search for the devices.
On a smartphone (for example, Xiaomi 13T with HyperOS):
- Go to Settings → Connections and Sharing → Screen Transfer.
- Slip the name of your TV in the list of available devices.
- Confirm the connection on both devices (may be required) PIN-code).

⚠️ Note: Some Xiaomi TVs (e.g. Mi) TV Q1 75") Miracast is hidden. To activate it, press the Menu button on the remote for 5 seconds, then select Engineer Mode. → Wireless Display → Enable.
Method 2: DLNA – Translating media files over a local network
The DLNA protocol is designed to transfer only media files (video, music, photos), not the entire screen.
- 🎵 Support for high bitrate (up to) 4K HDR stable-wi-fi).
- 📂 Ability to transfer playlists and folders entirely.
- 🔄 Low delay (~20-30 MS), suitable for music.
Instructions for television:

On a smartphone (MIUI 14/HyperOS):
- Open the gallery or the music.
- Select files, click Share → Transmit to the device.
- Choose your TV from the list.

| FLAC | 24-bit/192kHz | Yes (starting with Mi TV P1) |
| AVI (Xvid) | 1080p | Partially (requires conversion) |
💡
If the video slows down when broadcasting over DLNA, try to reduce the bitrate in the settings of the Gallery application: Settings → File Transfer → Video quality → Average.
Method 3: Apple AirPlay on Xiaomi TVs (2022 and later)
Xiaomi TVs released after 2022 (Mi TV Q2, P1, A Pro series) support the Apple AirPlay protocol, despite the lack of official Apple certification.This allows you to broadcast the screen from an iPhone or even from Android smartphones through third-party applications.
The algorithm of connection from the iPhone:

- On your TV, open Settings → Apple AirPlay and activate the feature.
- On the iPhone, swipe down to call Control Point, press Screen Duplication.

⚠️ Note: When using AirPlay on Xiaomi TVs, you may experience an error "Device not certified". Solution: in the router settings, disable the function AP Isolation (customer isolation).
Method 4: Broadcasting applications (for older TV models)
