Modern Xiaomi Mi TVs and Mi Box consoles have powerful multimedia filling, turning a regular screen into a full-fledged entertainment center. However, embedded applications can not always play a specific format of a video file or run content from a closed source, which forces users to look for alternative ways. Transferring images from phone to TV becomes not just a convenient option, but a necessity for comfortable viewing of personal archives, presentations or games.
In this article, we will take a closer look at all the existing broadcasting methods, from wireless protocols to physical cables, relevant for 2026-2026. You will learn how to set up Miracast for instant screen duplication, how to use DLNA technology to stream video without loss of quality, and what nuances the connection through Google Home has. Understanding the differences between these technologies will allow you to choose the best scenario for each specific situation.
The setup process may seem complicated at first glance, but it only takes a few minutes to meet basic requirements. The key to the stable operation of most wireless methods is finding devices on the same LAN. We will look at typical connection errors and how to fix them so that you can enjoy content on the big screen without delays and artifacts.
Wireless streaming via built-in Chromecast
The Android TV operating system that powers Xiaomi Mi TVs has deep-integrated support for Google Cast technology. It’s the most stable and high-quality way to transmit an image, as it uses hardware decoding of the TV, rather than just streaming video from the smartphone screen. It’s critical that your mobile phone and TV are connected to the same Wi-Fi network, ideally 5GHz.
The process of launching the broadcast begins with opening any application that supports the casting function, such as YouTube, Netflix or Vimeo. In the player interface, you need to find the characteristic icon of the rectangle with waves, which is usually located in the upper or lower corner of the screen. After clicking on the icon, the system will search for available devices on the local network and offer a list where you want to select the name of your Xiaomi TV.
⚠️ Note: If the Cast icon doesn’t appear, make sure that Bluetooth and geolocation are enabled on the phone, as the Google Cast protocol uses them to initially detect devices on the network.
The advantage of this method is that you can use the phone as a remote control: you can pause the video, rewind or adjust the volume, and it will not interrupt the playback on the TV. Moreover, once you start playing, you can turn the application or even lock the smartphone — the video will continue to go on the big screen, this frees up the resources of the mobile device and saves battery power.
Why is Chromecast better than screen duplication?
Duplication of screen through Miracast protocol
Unlike Chromecast, which requires support from a specific application, Miracast technology (often called Transcription or Wireless Display on Xiaomi devices) allows you to completely clone an image from your smartphone screen to your TV. This method is ideal for showing photos from a gallery, showing presentations or games that do not have built-in caste support.
To activate the mode on the Xiaomi Mi TV, you need to go to the application menu and find the Wireless Display or Tranulation program. After running the application, the device's name will appear on the screen. On the smartphone side, the process may differ depending on the shell: on pure Android, you need to go to Settings → Connected devices → Connect to the TV, and on MIUI it is enough to develop the notification curtain and press the Broadcast button.
It is important to consider that when you duplicate the screen, the resolution and refresh rate are synchronized with the mobile device, which can lead to black bars on the sides if you are not able to see the screen. ratio_ The phones and TVs don't match, and in this mode, the smartphone screen should stay on, as it acts as a source of video. To minimize delays in games, it is recommended to switch the phone to Do Not Disturb mode, so that incoming notifications do not block the image.
Using the Google Home app to manage
The universal tool for owners of the Google ecosystem is the official Google Home app, which allows not only to manage a smart home, but also to force the contents of the smartphone screen to any compatible Xiaomi TV, even if the phone does not have a separate “Translation” button, which is especially true for older versions of Android or specific firmware assemblies.
Once you install and configure the app, the main window will display all available devices on your network. If you select your Xiaomi Mi TV, you will see a control card, where the Cast My Screen button will be located at the bottom. Pressing this button initiates a request for permission to access media files and microphone, after which the image from the phone will appear on a large display.
- 📱 It allows you to broadcast the screen even those applications that block the regular Chromecast.
- 🔊 Transmits sound through the TV even if the app does not support audio output over the network.
- 🔄 Works more stable than standard Android tools on some smartphone models.
The app’s functionality also allows for multi-room audio device groups, but in the context of video transmission, its main value is the reliability of the connection. If standard methods fail or permanently break communication, Google Home often acts as a “heavy artillery” capable of establishing a stable bridge between devices.
💡
To reduce latency when streaming through Google Home, close all background apps on your smartphone and approach the router to ensure the maximum speed of the Wi-Fi signal.
File Transfer and Streaming via DLNA
DLNA (Digital Living Network Alliance) is a classic standard for sharing multimedia content on a local network. Unlike mirroring, DLNA allows you to transfer only the file (video, photo or music) to the TV, which is then played by the built-in player of the TV, this is the most energy-efficient way to view downloaded movies or photo albums.
Xiaomi TVs already have a standard media player that supports this feature, but for advanced features, it is recommended to install a third-party server, such as VLC for Android or BubbleUPnP on a smartphone. The phone's file manager (such as MI Downloads or Files by Google) often has a built-in "Translate" feature or DLNA icon that allows you to send a selected file to an available device.
| Protocol | Type of transmission | Phone load | Quality. |
|---|---|---|---|
| Miracast | Screen duplication | Tall. | Depends on Wi-Fi. |
| Chromecast | Streaming link | Low. | Maximum. |
| DLNA | File transfer | Medium | Original |
Main advantage DLNA The problem is that the phone doesn't have to decode the video file. You can run a heavy file. 4K-The movie is a high bitrate movie, and the phone will only act as a storage, transmitting data stream, and the TV will take over all the work of processing the image, which ensures smooth playback even on powerful files.
Wired connection via USB and HDMI
When wireless networks are overloaded or image transfer is required without the slightest delay (for example, for games), physical interfaces come to the rescue. USB and HDMI, And that's a real possibility, but there's a big caveat: you can put your phone directly into the phone. HDMI-port is not possible, a special adapter (adapter) is required USB-C to HDMI).
When using an adapter, the phone defines an external display and can operate in two modes: simple duplication or extended desktop (if supported by a smartphone manufacturer, such as Samsung DeX or Huawei Easy Projection), in which case the TV becomes a second monitor, and the phone turns into a trackpad or keyboard.
☑️ Checking readiness for wired connection
An alternative wired method is to connect via a USB port, in which the phone is defined by the TV as an external drive, you can't broadcast the system interface, but you can access all the files in the device's memory, and it's the perfect way to quickly show family photos from a vacation or run a video file that for some reason is not readable online.
Problem Solving and Network Setup
The most common reason for failure when trying to connect a Xiaomi phone and TV is the wrong network configuration.The Miracast and DLNA protocols require devices to be in the same subnet segment. Problems can arise if the router divides the 2.4 GHz and 5 GHz bands into different SSIDs, or if the Guest Network feature is enabled, which isolates customers from each other.
To diagnose the problem, try pinging your TV from your phone through special network utilities or simply check the visibility of the devices in the router. If the TV is not visible, try temporarily turning off mobile Internet (3G/4G/5G) on your smartphone, as some Android algorithms prioritize the mobile network and ignore local device search over Wi-Fi.
⚠️ Warning: Antivirus programs or firewalls on your smartphone can block incoming and outgoing connections for local devices. If you have connection problems, try temporarily disabling network protection.
It is also worth checking the date and time on both devices.Dissynchronization of the watch can lead to security certificate errors, which can cause secure data transfer protocols (DRM) to block the connection.Make sure that both devices have an option to automatically synchronize time over the network.
