The modern smart home ecosystem allows you to turn ordinary video watching into a full-fledged multimedia experience. Synchronization of a smartphone and a Xiaomi TV gives you access to content management, screen broadcasting and use of a mobile device as a remote control. This process does not require deep technical knowledge, but has its own nuances depending on the version of the MIUI operating system and the TV model.
Owners of Xiaomi equipment often wonder how to effectively combine their gadgets for maximum comfort. The answer lies in the use of built-in wireless protocols and specialized applications. Proper configuration allows you to broadcast photos, videos and even games from your phone to the big screen without delay and loss of quality.
In this article, we will take a closer look at all the ways you can connect, from standard system functions to advanced methods via Wi-Fi Direct. You will learn how to avoid common errors and ensure a stable connection between devices.
Preparatory stage and network requirements
Before setting up, make sure that both devices are in the same network conditions. It is critical that the smartphone and TV are connected to the same router. Splitting into a guest network or using different frequencies (2.4 GHz and 5 GHz) can in some cases prevent devices from being detected by each other.
Check the software on both gadgets. On your TV, go to Settings → Device → System Update. On your smartphone, the path usually looks like Settings → Phone → MIUI version. Updated Wi-Fi drivers and Bluetooth modules provide better data protocol compatibility.
⚠️ Note: If your router supports the “Customer isolation” function AP» (AP Isolation, be sure to disable it. This feature blocks the exchange of data between devices within the same local area network, which will make synchronization impossible.
It's also worth freeing up RAM on your smartphone, closing the background apps before you start broadcasting heavy. 4K-Video will help avoid micro-delays and image jerks.Make sure the phone is on Bluetooth module, as some primary pairing methods use it to shake hands.
☑️ Checking before connection
Use of the built-in Translation (Miracast) function
The fastest way to display a smartphone image on a TV screen is to use Miracast technology, which is called a “Translation” or “Wireless Monitor” in the MIUI shell, which allows you to completely duplicate the screen of a mobile device, which is ideal for displaying presentations or games.
To activate a feature on a Xiaomi TV with Android TV or PatchWall, you need to find the Wireless Connection or Miracast app in the installed program list. On some models, just click the Menu button on the remote and select the source of the Wireless Display signal.
On your smartphone, open the notification curtain and find the Translation button. If it's not on the home screen, click on a pencil or three dots to edit the Quick Access panel. Once you turn on the search, the phone will start scanning the available displays. Choose your TV from the list.
- 📱 Make sure that the smartphone screen does not go out during the broadcast, otherwise the signal may be interrupted.
- 📶 For stable operation, it is desirable to use Wi-Fi 5 GHz band, it is less loaded.
- 🔋 Screen broadcasting significantly consumes the battery of a mobile device.
Image quality is directly dependent on the power of the Wi-Fi signal. If you notice a desynchronization of sound and video, try to approach the router or reduce the load on the network by turning off downloads on other devices.
💡
To reduce latency (input lag) during games, turn on the “Game” mode on the TV or turn off post-processing of the image in the display settings.
Mi Remote: Control and Synchronization
The official Mi Remote app (or “Mi Remote”) is the main tool for deep integration of the smartphone into the Xiaomi ecosystem, which allows you not only to control the TV as a remote, but also to transfer media files, as well as use the “Translation” function through the program interface.
After installing the app and adding the TV (automatically or manually) IP-The interface has a "Translation" button or screen icon, and clicking on it starts a search for available devices, the advantage of which is that the application often has more extensive permissions to access the TV system than standard Android tools.
In some versions of PatchWall, the app allows you to transfer photos and videos from the gallery directly, without duplication of the entire screen, which is convenient when you need to show friends an album from vacation without being distracted by phone notifications.
| Function | Standard broadcasting | Mi Remote | YouTube/Netflix |
|---|---|---|---|
| Screen duplication | Yes (full) | Yes (full) | No (content only) |
| Volume control | Depends on the model. | Yes (full) | Yes (in annex) |
| Working in the background | No (screen on fire) | Partially. | Yes. |
| Battery consumption | High-pitched | Medium. | Low. |
Importantly, both devices require permission to access the local network to operate Mi Remote, and when you first start up, Android may request confirmation — be sure to select “Allow”.
Broadcasting via Chromecast and Google Home
Most modern Xiaomi TVs run on Android TV, which implies built-in support for Chromecast technology. This is the most stable way to transfer content from specific applications such as YouTube, Netflix, Twitch or Google Chrome browser.
Unlike Miracast, it's not a backup, it's a stream link. The TV downloads the video from the Internet on its own, freeing up the smartphone for other tasks and saving it battery. The phone screen can be locked or used for calls, and the playback on the TV will not be interrupted.
To run, look for a source app (like YouTube) that has a characteristic rectangle icon with waves in the corner. Click on it and select your Xiaomi TV from the list. If you don't find a device, make sure that the Google Home app identifies the TV as an available broadcast device.
⚠️ Note: Chromecast technology does not support the transfer of protected content (DRM) from some file managers or browsers if the site is not optimized for Cast.
The quality of the video streamed via Chromecast is often higher, as the TV uses its own decoder and network module for buffering, regardless of the real-time data transfer speed over Wi-Fi Direct.
Connection problems and their solution
Despite the ease of setting, users often experience a situation where the TV is not visible in the list of available devices, the most common reason is the use of different subnets «Home_2.4» and «Home_5G», And the devices are connected to different names, they may not be able to "see" each other.
Another common problem is antivirus software or a smartphone firewall that blocks local connections. Try temporarily turning off protection or adding a TV to the exclusion list. Also, rebooting the network module helps: turn on and off In-Flight mode on your phone.
- 🔄 Reboot the router – it solves 90% of the problems with the DHCP distribution IP-address.
- 📡 Check if the phone is on “Saving Traffic” mode, it can block local search.
- 📺 On the TV in the network settings, you sometimes need to re-accept the terms of use of the services.
If nothing helps, try static. IP-Go to the Wi-Fi settings on your TV, select your network and in the settings. IPv4 set a static address that matches the phone subnet (for example, if the phone is 192.168.1.5, then do TV 192.168.1.20).

Alternative methods: HDMI and third-party software
When wireless methods fail to produce the desired result or require maximum image quality without compression, a cable connection comes to the rescue. Using a USB-C to HDMI adapter allows you to output the image directly.
This will require an HDMI adapter and cable. Connect the narrow end to the smartphone charging connector and HDMI to the TV. Switch the TV signal source to the appropriate port (HDMI 1, HDMI 2). Most modern Xiaomi smartphones with Snapdragon processors support image output.
Another option is to install third-party repetitive apps like AirScreen or ApowerMirror, which are installed on a TV (via the Google Play store on TV) and on a phone, and these programs often have their own codecs, which improves compatibility with older routers.
⚠️ Note: When using cheap adapters USB-C to HDMI The sound may not be transmitted, in which case you will need to connect the Bluetooth headphones to the phone or use external DAC.
The cable connection is ideal for gaming, as it provides a minimum input delay (input lag), unattainable for wireless technologies in noisy ether.

Cable connection via HDMI-Adapter is the only way to guarantee zero latency and maximum bitrate quality for games and professional tasks.
