Xiaomi smartphone owners often face the desire to bring an image from a mobile device to a large TV screen, whether for watching movies, presentations or mobile gaming. Current technologies of the MIUI and HyperOS ecosystem offer many built-in tools to accomplish this task without having to buy additional gadgets. Understanding the differences between broadcast technologies will allow you to choose the most suitable method for your particular situation.
The wireless data transfer process is based on Wi-Fi Direct and DLNA protocols, which are supported by most modern Smart TVs. Wireless transmission provides high connection speeds, but requires a stable router signal. At the same time, wired methods ensure no delays, which is critical for competitive games or working with dynamic content.
In this article, we will take a look at the standard system features, third-party apps, and physical connectivity, learn how to set up a wireless monitor in a couple of touches, and what to do if standard methods donโt work, and explore the nuances of working with different TV brands such as Samsung, LG, and Sony.
Use of the built-in Translation function in MIUI
The easiest and fastest way to display an image is to use the native operating system function, which is called Translation or Wireless Monitor in MIUI and HyperOS shells, and is based on the Miracast protocol, which allows you to stream video and audio in real time without using a router, creating a direct connection between devices.
To activate the function, unlock your smartphone and lower the notification curtain. Find an icon called Translation (sometimes hidden in the optional swipe menu to the left). Once you click, you will start searching for available devices within range. The TV will have a signal reception mode that is often called Screen Mirroring, Miracast or Wireless Display.
โ ๏ธ Note: If your TV doesnโt support Miracast natively, you wonโt see it on the list of available devices using the standard method.
And it's important to note that the quality of the image is directly dependent on the power of the Wi-Fi signal. You can have a little cursor or sound latency using Miracast, which is normal for this technology. But if you're going to be able to view a photo gallery or video from your phone's memory, if you're going to be showing slides or playing games, you better check the connection stability in advance.

For better connectivity stability, make sure both devices are Wi-Fi enabled, even if they are directly connected, which improves handshake and data exchange speed.
Broadcasting through the Google Home app
If the built-in tools donโt work or your TV is running Android TV or Google Cast, the best solution is the official Google Home app, which uses Chromecast built-in technology, which provides more stable media content transfer and allows you to control the TV directly from your smartphone.
Before you start, make sure that both devices are connected to the same Wi-Fi network. This is a critical condition, since Google Home only searches for devices within the local subnet. Open the app, find your TV in the list, and click on the Translate screen button. The system will request confirmation, after which the image from the Xiaomi phone will appear on the large screen.
- ๐บ Supports the broadcast of Chrome browser tabs for viewing web pages on TV.
- ๐ฎ Allows you to display images from games that do not support native Cast.
- ๐ Provides synchronization of sound with minimal latency when using compatible applications.
The advantage of this method is that you can run a video on your phone and then you can flip it onto your TV, and you can still use your smartphone for other tasks, which is especially useful when you're watching long video files or streams, where you don't need to constantly interact with the interface.
Specialized applications for Smart TV
Owners of Samsung, LG and other brands that donโt run Android TVs may face the limitations of standard protocols, and in these cases, developers have created customized applications that act as a bridge between the phoneโs file system and the TVโs media player, with Smart View (for Samsung) and LG ThinQ being the most popular solutions.
Installing a TV manufacturer's proprietary app allows not only the screen to be broadcasted, but also the smartphone to be used as a remote control, giving you access to image settings, sound profiles and the menu of TV applications, and the interface of such programs is usually adapted for large screens, which makes navigation comfortable.
Letโs consider the main features of popular broadcasting applications:
| Annex | Compatibility | Type of connection | 4K support |
|---|---|---|---|
| Smart View | Samsung Tizen | Wi-Fi / DLNA | Yes. |
| LG ThinQ | LG webOS | Wi-Fi Direct | Yes. |
| Video & TV Cast | Universal. | DLNA / Chromecast | Depends on TV. |
| BubbleUPnP | Universal. | DLNA / Chromecast | Yes. |
When using third-party applications, it is important to pay attention to the permissions they request. To work correctly, the program needs access to the local network and media files. Without these permissions, the application will not be able to find the TV or read the video file to play.
Why can't the app see the TV?
Wired connection via USB-C to HDMI
For users who want maximum image quality and no delays, wired connectivity is ideal. Xiaomi mid-range and flagship smartphones often feature a USB Type-C port with video output support.
Connection is done according to the scheme: smartphone โ USB-C to HDMI adapter โ HDMI cable โ TV. Once connected, the phone automatically determines the external display. In settings โ Connected devices โ HDMI, you can select resolution, refresh rate and display mode (mirror or extended desktop).
- ๐ Ensures signal transmission in resolution 4K at 60 Hz without compression.
- โก Simultaneously charges the device if the adapter has a power port.
- ๐ฎ Ideal for games where every millisecond of response is important.
Note that not all Xiaomi models support video output via USB. Budget devices may have a port only for charging and data transfer. Before buying an adapter, it is recommended to check the specification of your smartphone processor or whether you support the MHL or DisplayPort Alt Mode standard.

Wired connection is the only way to get a picture without compression artifacts and delays, making it indispensable for professional presentations and eSports.
Broadcasting video from browsers and online cinemas
The broadcasting of content from online services deserves special attention. Most modern platforms, such as YouTube, Netflix or IVi, have a built-in Cast button. Unlike mirror display, in this case the phone acts only as a remote control, and the video stream is downloaded by the TV directly from the Internet.
This approach saves a smartphone battery and reduces the load on the processor, and the video quality is limited only by the speed of your Internet connection and the TV, not the power of the phone, and you just need to click on the Cast icon in the corner of the video player to start.
If you don't have a built-in button, you can use Google Chrome on your phone. Open the page you want, click on the three-dot menu, and select Translate. The browser will suggest you choose the device and the type of broadcast: tab or full screen. This is a universal method for sites that do not have their own Cast-enabled player.
โ ๏ธ Attention: When broadcasting through the browser in the background, heavy scripts may continue to work, which will lead to increased energy consumption.
Solving Connection and Delay Problems
Although easy to set up, users may face a number of technical problems, most commonly audio and image desynchronization or periodic twitching, usually indicating Wi-Fi overload or insufficient network bandwidth.
To diagnose the problem, try rebooting the router and both devices, and check if the connection is busy with other heavy tasks, such as downloading files or updating games. If the problem persists, try switching to the 5GHz band, which is less busy and provides higher data rates.
Another common reason for failure is the firewall or antivirus settings on the router, which can block local traffic. Temporarily disable network protection for verification. If the broadcast has started, add the devices to the exclusion list.
โ๏ธ Diagnostics of translation problems
In case none of the software methods worked, it remains to check the physical integrity of the antennas and modules. Sometimes a software failure can be corrected by resetting the network settings to factory, but remember that this will delete all stored Wi-Fi passwords.
