Xiaomi’s modern Smart TVs have long since ceased to be just on-air TV viewing devices, becoming powerful multimedia centers. One of the most popular features is the ability to display images from a smartphone or tablet to a large screen, allowing you to enjoy movies, photos and games in high resolution. Users often wonder how to broadcast a screen to Xiaomi TV to avoid unnecessary wires and complex equipment setup. This process, known as screencasting or mirroring, is built into the shell of MIUI TV and is available by default.
There are several ways to implement this feature, each with its own characteristics and suits different use cases. You can use Miracast embedded protocols, Google Chromecast technologies or specialized applications for the use of the software. DLNA-It is important to understand that the quality of the connection depends on the stability of your local Wi-Fi network. In this article, we will discuss all available methods, consider the nuances of configuring different operating systems and help eliminate common connection errors.
Before you start setting up, make sure that both your mobile gadget and your TV are connected to the same wireless network. This is a critical condition for most data protocols to work without delay. If the router supports dual-band mode, it is advisable to use a 5 GHz network to transmit high-resolution 4K video, since the 2.4 GHz standard may not be able to cope with the flow of data.
Equipment preparation and network inspection
The first step to a successful broadcast is to prepare the infrastructure correctly. Make sure your Xiaomi TV or Mi Box has the latest firmware version. Manufacturers regularly release updates that improve the stability of wireless modules and add support for new codecs. You can check for updates in the system settings section by selecting “About TV” and then “Update system”.
You should also pay attention to router settings. Some providers or router models have a "Client Isolation" feature that prevents devices connected to Wi-Fi from communicating with each other. If this feature is activated, the TV simply won't "see" your phone, even if they're on the same network. To solve the problem, you need to log into the router's admin panel and turn off this option in the wireless settings section.
Be sure to check whether Bluetooth is enabled on both devices.While video transfer is over Wi-Fi, Bluetooth protocol is often used for initial device discovery and fast pairing, especially in the Xiaomi ecosystem.If you use a third-party router, make sure it doesn't create a separate guest network isolated from the main one, as this will also cut communication between gadgets.
☑️ Checking before connection
Use of the built-in Translation (Miracast) function
The easiest and fastest way to do this without having to install any additional software is to use the native broadcast function. On Xiaomi TVs with PatchWall shell or Android TV, this feature is often called Translation or Wireless Display. You need to open the app menu on the TV and find the appropriate shortcut. Once launched, a message will appear on the screen about waiting for connection.
On an Android smartphone, the process can be called differently depending on the manufacturer's shell version. Usually it's Translation, Smart View, Wireless Monitor or Projection. You can find it in the notification curtain or in the screen settings. After scanning the available devices, select your Xiaomi TV from the list. The image from your smartphone will appear on the TV almost instantly.
⚠️ Note: When using Miracast, the screen of the smartphone is completely duplicated on the TV, which means that all notifications, incoming calls and messages will be visible to everyone in the room.
The image quality of this connection can vary. If you notice the sound and video being out of sync or artifacts appearing, try reducing the resolution of the output image in the phone settings or getting closer to the router. Miracast protocol is sensitive to interference, so direct visibility between the router and the signal receiver is desirable.
Why can the broadcast be interrupted?
Google Home (Chromecast built-in)
Most modern Xiaomi TVs run Android TV, which implies built-in support for Google Cast technology. This is a more advanced protocol than Miracast, since it allows you not only to duplicate the screen, but also to send content directly from the server to the TV, freeing up the resources of the smartphone.
Launch the Google Home app and wait for it to find your TV on the local network. Click on the device icon, then select the "Cast screen" button. The system will alert you that the sound and image from the smartphone will be broadcast to TV. Confirm the action, and in a few seconds the transmission will begin.
The main advantage of this method is the ability to control playback from the phone without having to keep the screen constantly active, and many applications such as YouTube, Netflix and Movie Search have their own Cast button inside the interface, allowing you to send videos directly, bypassing the system menu of the broadcast, which ensures the best picture quality and stability.
| Characteristics | Miracast (Translation) | Google Cast (Chromecast) | DLNA (Media Server) |
|---|---|---|---|
| Type of transmission | Screen mirroring | Streaming transmission/Mirroring | Media files only |
| Dependence on the phone | High (screen active) | Low (you can use other apps) | Medium (music player needed) |
| Sound quality | Depends on the CPU boot | High, separate flow | Original file |
| Support for iOS | No (crutches required) | Yes (via annexes) | Yes. |
💡
For maximum video quality in 4K HDR via Chromecast, make sure that the Google Home app has 4K Mode enabled in your device settings and selects high stream quality.
Broadcast from Apple devices (AirPlay on Xiaomi)
iPhone and iPad owners have long been limited in their ability to connect to non-Apple TVs, but Xiaomi has implemented AirPlay 2 support in many of its Smart TV models. This allows iOS users to stream screen or media content as easily as they would on Apple TV. To check for support, go to the TV settings, Network or Apple AirPlay section and make sure the feature is enabled.
To start streaming, open Control Point on your iPhone (swipe down from the top right corner on new models or swipe up on old ones). Click Screen Replay (two rectangles) and select your Xiaomi TV from the list. If the devices are on the same network, the connection will set up automatically. You can choose the display mode: mirror repetition or screen extension (if the app supports).
Importantly, AirPlay’s stability on Android TVs may be inferior to Apple’s original devices.There is sometimes a slight delay in displaying images, making the technology unsuitable for dynamic games, but well suited for watching videos and presentations. If the built-in support is unstable, you can use third-party apps from the Google Play store emulating an AirPlay receiver, such as AirScreen.
⚠️ Note: When streaming from iOS via AirPlay, the sound may be delayed. If you are watching a movie, use the built-in player of the TV or app with Cast support, rather than the system mirror of the screen to avoid lip and sound dissynchronization.
Use of the DLNA-media-server
If your goal is not to duplicate the screen, but to view photos, videos, or music stored on your phone, DLNA technology is perfect. It doesn't put a strain on the smartphone's processor, because the phone is just a remote control and storage device, and the TV is decoding. To implement this method, you need to install a DLNA-enabled application on TV, such as VLC for Android or a built-in Media Player.
A smartphone will also require a server app. Xiaomi owners are often advised to use the built-in Mi File Manager Explorer or the "Mi Remote" app. In the explorer, select the desired video, click the "Translate" or "Cast" button, and the phone will suggest a list of available devices. Once you select the TV, you will start playing the file directly on the large screen.
This method is especially useful for viewing “heavy” files with high bitrate, which can slow down when wirelessly mirroring the screen. The DLNA protocol allows you to buffer data, providing smooth playback even with a imperfect Wi-Fi signal. However, it is worth remembering that the interactive possibilities here are limited: you can only control playback (start, stop, rewind), but you will not be able to show the interface of messengers or the browser.
💡
DLNA is the best choice for viewing high quality local video files, as it minimizes the load on the smartphone battery and ensures a stable data flow.
Solving problems and fixing connection errors
Despite the technology, users may face problems: the TV can’t see the phone, the connection is constantly broken or there is no sound. One of the most common reasons is the use of different Wi-Fi frequencies. Make sure that both devices are connected to the same network (for example, both at 2.4 GHz or both at 5 GHz), and not spread over different guest networks of the router.
If the problem is a software failure, try resetting your network settings on your TV. Go to Settings → Network and Internet and select Forget Network, then reconnect by entering your password. It is also useful to reboot your Wi-Fi module or fully restart your device. In rare cases, cleaning the cache of the system application Translation in the Android TV application settings section helps.
Another reason could be antivirus software or a firewall on a router blocking the ports needed to transmit media traffic. Try temporarily disabling protection or adding devices to the trusted list. If nothing helps, check if the TV is power-saving screen mode is on, which can interrupt the connection in the absence of active actions.
⚠️ Warning: Never interrupt the TV firmware update process while trying to establish a connection. If the stream doesn't work after the update, perform a full Factory Reset, as old network configurations may conflict with new drivers.
