Modern Xiaomi TVs (series Mi) TV, Redmi Smart TV, Xiaomi TV A) support many ways to wirelessly and wiredly transmit video from mobile devices, but not all methods are equally convenient: somewhere you need stable Wi-Fi, somewhere you need special adapters, and in some cases, a standard adapter is enough. USB-The main problem for users is choosing the best option depending on the phone model, the version of TV firmware and the available equipment.
In this article, we will discuss all current ways of connecting (including hidden functions). MIUI We will compare them in speed, transmission quality and compatibility, and give recommendations for eliminating typical errors - from lack of sound to "hang" of the screen. Mi Quick Connect technologies for instant synchronization or support DLNA non-partisan.
If you want to not just put video on TV, but to have a full-fledged media server with a phone as a remote, read the section on companion apps. And for older models (until 2020), we have prepared separate instructions with workarounds.
1. Wireless transmission via Miracast (Screen Mirroring)
Miracast (or Screen Mirroring) technology allows you to duplicate your phone screen on a Xiaomi TV without wire using a direct Wi-Fi signal between devices. This is the most versatile method, since it works on all Android smartphones (starting with version 4.2) and iPhone (with limitations).
On Xiaomi TVs, Miracast is built into firmware and activated via the Settings menu โ Connection and Sharing โ Wireless display. On a smartphone, the path depends on the manufacturer:
- ๐ฑ Xiaomi/Redmi/Poco: Settings โ Connection and sharing โ Transmission to the screen (or Cast)
- ๐ฑ Samsung: Notification panel โ Smart View
- ๐ฑ iPhone: Control point โ Screen duplication (Apple required) TV adapter)
An important nuance: on some Xiaomi TV models (for example, Mi TV 4A 32), Miracast works only after updating the firmware to MIUI TV 3.0+. If the menu does not contain the option โWireless displayโ, check the version in Settings โ About TV.
โ ๏ธ Note: When using Miracast on iPhone, the image can be transmitted with black stripes on the sides due to the difference in aspect ratio. โ Screen size).

2. Connect via Google Cast (Chromecast)
If your Xiaomi TV supports Google Cast (built into Android TV models like Mi TV Q1E or Xiaomi TV A Pro), you can stream videos from apps like YouTube, Netflix or Google Photos directly to the big screen. Unlike Miracast, it only transfers content, not the entire screen of the phone, saving battery life and reducing network load.
Instructions for setting:
- Make sure your phone and TV are connected to the same Wi-Fi network.
- Open a supported app (like YouTube) and tap on the Cast icon (usually in the upper right corner).
- In the list of devices, select your Xiaomi TV (the name will be in MiTV-[code] format).
- Start the video and it will start playing on TV.
List of apps that support Google Cast on Xiaomi TV:
- ๐ฌ YouTube, Netflix, Disney+
- ๐ต Spotify, Yandex Music (Audio only)
- ๐ท Google Photos, Xiaomi Gallery (for photo/video)
- ๐ฎ Stadia, NVIDIA GeForce NOW (play-off)
โ ๏ธ Note: On Xiaomi TVs with PatchWall firmware (e.g. Mi) TV 4X) Google Cast may not be available, in which case, install the Google Home app on your phone and add TV manually via Add Device โ Set-up of a new device.

If video slows down when streaming via Google Cast, reduce the quality in the app settings (for example, on YouTube, choose 480p instead of 1080p).
3. Wired connection via USB (MTP/PTP)
The most reliable, but least universal way to connect your phone to a Xiaomi TV USB-This method is suitable for watching local videos (recorded to a phone), but does not support streaming (for example, from YouTube or TikTok), the main advantage is the lack of latency and dependence on Wi-Fi.
Step-by-step:
- Connect your phone to a USB 2.0/3.0 port on your TV (usually on the side or back).
- On the TV screen, select the source of the signal - USB (Source or Input button on the remote).

A critical feature: Xiaomi TVs do not support the exFAT file system format on connected devices. If your phone is formatted in exFAT (often on smartphones with a memory card >64 GB), the video will not show up, the solution is to reformat the flash drive to FAT32 or use another connection method.

|---|---|---|---|
| Mi TV 4S/4X | Yes (renewal required) | 4K@30fps | Yes (AAC, MP3) |

4.Using DLNA/UPnP for local area network streaming
DLNA allows you to stream video from your phone to your Xiaomi TV over your home network without any additional adapters. Unlike Miracast, it doesn't duplicate the screen, it only transfers the media file, which reduces the load on the phone's processor. The method works on all Mi TV/Redmi TV models, but requires you to install a special application on your smartphone.
The best apps for DLNA on Android:
- ๐บ BubbleUPnP โ Supports subtitles and transcoding;
- ๐ฅ LocalCast โ a convenient interface for video and photos;
- ๐ MediaHouse UPnP Browser โ for advanced users.
How to set up DLNA on Xiaomi TV:
- Install one of the apps above on your phone.
- Open it and allow access to the files.
- In the list of devices, select your TV (the name will be MiTV-[model]).
- Select a video and click Play. The content will start streaming on TV.
โ ๏ธ Note: On Xiaomi TVs with PatchWall firmware (e.g. Mi) TV 4C) function DLNA It's disabled by default. To activate it, go to Settings. โ Annexes โ System applications โ Media server and switch on the switch.
Why is DLNA better than Miracast for video?
5. HDMI connection (for iPhone and older Android)

HDMI-Connection is the only way to transfer video from iPhone to Xiaomi TV Apple TV. However, adapters often warm up, so it is not recommended to use them for longer than 1-2 hours in a row.
6. Companion apps from Xiaomi (Mi Home, Mi Remote)
For owners of the Xiaomi ecosystem, there is a unique opportunity to control the TV directly from the phone through branded applications. For example, Mi Home allows you not only to transfer video, but also to use the phone as a remote with a touch panel or voice control.
