Modern Xiaomi smartphones have powerful screens, but to view content in the company or just for greater comfort, it often becomes necessary to duplicate the image on a large display. Fortunately, the shell MIUI and HyperOS already have all the necessary tools in place to do this without buying expensive cables or adapters.
There are several basic video protocols, each with its own characteristics: Miracast provides a direct connection, Google Cast requires a Chromecast, and DLNA allows you to stream only media. In this article, we’ll break down all the available ways so you can choose the best option for your situation and enjoy content on the big screen.
Before you start setting up, it’s important to understand that the quality of the image you’re sending depends on the speed and stability of your router. If the video is twitching or low resolution, try getting closer to the access point or disconnecting other devices that consume a lot of traffic.
Wireless broadcasting through the built-in function "Translation"
The easiest and fastest way to duplicate Xiaomi’s screen on a TV is to use the native feature of the system, which is called “Translation” or “Wireless Monitor” in most models, which is based on Miracast technology, which is supported by almost all modern Smart TVs.
To get started, lower the notification curtain down and find the Translation icon. If it's not on the main panel, click on a pencil or edit button to add the widget to the active elements. Once activated, the phone will start searching for available devices within range.
You also need to start a service on your TV, depending on your TV brand, it can be called Screen Mirroring, Smart View, or just Wireless. Once the TV appears on your smartphone, click on it to pair.
☑️ Checking before connection
It is worth considering that using this method, the phone can get a little warmer, since the process of encoding the video stream requires processor resources. Also, latency can be from 0.5 to 2 seconds, which makes this method ideal for viewing photos and videos, but not very suitable for dynamic games.
Using Google Chromecast technology
If your TV doesn’t support Miracast natively but has built-in Android TV or Google Cast support, you can use the Google ecosystem. Many apps like YouTube, Netflix and Yandex.Cinema have a built-in broadcast button that works more stable than full screen duplication.
However, if you want to bring out a desktop or app that doesn’t have a casts button, use the Google Home app. download it from the Play Market if it’s not installed and start a device search. Find your TV in the list and select Translate Screen.
Solving delay problems
The advantage of the Chromecast method is that the phone acts only as a remote control, and the video stream is downloaded by the TV directly from the Internet, which saves battery power and frees up the processor for other tasks.
Broadcasting through applications-receivers on Smart TV
Owners of TVs with Tizen (Samsung) or webOS (LG) operating system may face a lack of direct support for Xiaomi protocols, in which case special intermediary applications that are installed directly on the TV come to the rescue.
One of the most popular solutions is AirScreen, or Receiver for Xiaomi, which, after you install it on your TV, creates a virtual device that your smartphone sees as your native wireless monitor, and then launch it on your TV and follow the instructions on the screen.
Then on your Xiaomi phone, turn on Translation or use third-party software like LocalCast. Find the name of the device that is displayed on your TV screen and connect. This method often allows you to adjust the resolution and frame rate manually.

|---|---|---|---|
| AirScreen | Android TV / FireOS | Yes. | Available (in the free version) |
| Yatse | Android TV | Yes. | No. |
| TV Cast | Samsung Tizen | Depends on the model. | There is. |
| Web Video Caster | All platforms. | Yes. | There is. |
It is important to note that using third-party apps on the TV can consume additional RAM of the Smart TV system. If the TV interface starts to slow down, close the background apps or restart the device.
Connection through HDMI-cable
For those who are the best picture quality without compression and delay, wired connection remains the leader. However, modern Xiaomi smartphones rarely have a full HDMI port, so you will need a special adapter.
You’ll need a USB Type-C to HDMI adapter. It’s important to understand that not all phone models support USB video output, a feature that is supported by flagship series like the Xiaomi 13/14 Pro, Mi 10/11 and some Mix series models that support DisplayPort Alt Mode.
⚠️ Note: Before buying an adapter, be sure to check the specifications of your phone model on the official website.Budget models (Redmi Note series, Poco) M/X) frequently USB 2.0, The adapter cannot transmit video signals, and the adapter will not work in this case.
If your phone supports video output, the connection process is elemental: insert the adapter into the charging port, connect the HDMI cable to the adapter and TV, then select the appropriate signal source (Source or Input) on the TV remote. The image will appear automatically, often the phone will go to desktop mode if the Desktop Mode function is enabled.
💡
Use a quality HDMI cable no longer than 2 meters long to minimize signal loss. Cheap long cables can cause interference or no image.
Transfer of media files via DLNA and local network
If your goal is not to duplicate the entire screen, but to simply show the family photos from the past vacation or to run a movie stored in the memory of the phone, the best way to use the DLNA protocol is to use the DLNA protocol.
Most TVs today have a built-in media player, and you just have to open a Media or Gallery app on your TV, select the source of Devices, and find your Xiaomi phone. In some cases, you may need permission to access files that will appear on your smartphone screen.
Alternative and more flexible option is to use the Xiaomi Mi Remote app (if the TV supports an infrared port or is on the same network) or third-party file managers with DLNA support, such as MX Player or VLC. In these players, you need to select the "Renderer" or "Cast" item and specify the target device.
The main advantage of DLNA is that you can continue to use your phone for calls or correspondence without interrupting the video playback on your TV, and the battery is minimally consumed, since only the control packets are transmitted, not the video stream.
Problem Solving and Frequently Asked Questions
Despite the simplicity of the technology, users sometimes have difficulty configuring the phone “can’t see” the TV, and 90% of the time, this is done by checking that both devices are connected to the same network (for example, the guest network and the main, or the 2.4 GHz and 5 GHz bands are not mixed up).
Another reason could be outdated software, check for updates to MIUI/HyperOS and TV firmware, and sometimes manufacturers add support for new codecs or protocols with updates.
💡
Connection stability is dependent on the router, and if you have an old router, it may not be able to handle streaming. HD-video, causing buffering.
⚠️ Note: When using Translation, incoming notifications, messages and calls will be displayed on the TV screen. To avoid embarrassing situations, activate Do Not Disturb in advance».
