Xiaomi’s modern Smart TVs, powered by Android TV or PatchWall, offer huge multimedia capabilities. However, smartphone screens, even the most advanced models, are physically limited in size, and it can be tedious to look at family photos or favorite TV shows on a 6-inch display. Fortunately, Xiaomi’s ecosystem has some simple and efficient ways to duplicate images or stream content directly to the big screen.
To do this successfully, you don’t have to be an expert in networking; it’s enough that your devices are on the same local network and you understand the basics of wireless data protocols. In this article, we’ll take a look at all the current techniques, from built-in smart screen features to using third-party applications for specific tasks.
You will learn how to stream videos from your browser, how to fully clone your smartphone screen to show presentations or games, and what nuances exist when connecting iOS devices. Properly configured will turn your TV into a full-fledged entertainment center, controlled by one touch.
Basic requirements and network preparation
A fundamental condition for any wireless data transfer between gadgets is that they are in a single information space.This means that both the smartphone and the Xiaomi Mi TV must be connected to the same router via Wi-Fi. If one device uses mobile Internet (4G/5G) and the other is connected to the home network, detection will be impossible.
The quality of the streaming video directly depends on the stability of the signal and the bandwidth of your wireless network.To view content in high resolution 4K or Full HD without delay and compression artifacts, it is recommended to use the 5 GHz frequency range. In congested apartment buildings, older 2.4 GHz networks may not cope with the streaming of heavy video.
⚠️ Note: When using guest Wi-Fi networks in hotels or hostels, the broadcast may not work due to customer isolation settings at the router level, which prevent devices from “seeing” each other.
Before you start setting up, make sure that the Wi-Fi module is on and is logged in to your home network. The smartphone also needs to check if Traffic Savings mode is activated, which can block background device discovery processes.
☑️ Checking before connection
Broadcasting through the built-in Chromecast feature
The most common and convenient way to output content is to use Google Cast technology (Chromecast built-in), which is sewn directly into the operating system of Xiaomi TVs. This method does not require duplication of the entire screen of the smartphone; instead, the phone acts as a remote control, sending the TV only a link to the video stream.
To implement this method, make sure that your mobile device has the latest versions of apps that support this feature, with YouTube, Netflix, Twitch and many other streaming services leading the way, and that the app interface always has a characteristic wave rectangle icon that symbolizes the broadcast.
The algorithm of actions is extremely simple: run the video on your smartphone, click on the broadcast icon and select from the list your Xiaomi TV. Once connected, the video will start playing on the big screen, and the phone can be used for other tasks or even turn off the screen without interrupting the viewing.
💡
If the Chromecast icon doesn’t appear in the app, try restarting the Google Home app or YouTube itself on your smartphone, as they are responsible for finding available devices online.
Importantly, the image quality is automatically adjusted depending on the speed of the Internet, and if the router is far from the TV, the system can lower the resolution to prevent buffering.
Screen Duplication (Miracast) on Android
This is a game changer when you need to show the contents of a screen that is not in standard applications, such as a photo gallery, a game interface or a closed-access browser. For this purpose, Miracast protocol is used, which in Xiaomi environment is often called “Translation” or “Wireless Display”.
Unlike the Chromecast, this method creates a direct connection between screens by streaming live video streaming. On Xiaomi TVs with PatchWall shell or pure Android TV, the signal reception function is usually enabled by default, but may require the launch of a special receiver app.
On Xiaomi smartphones, the path to this feature is most often in the notification curtain or in the settings:
- 📱 Open the control panel and find the “Translation” icon».
- ⚙️ Or go to Settings. → Connection and sharing → Broadcasting.
- 📺 After turning on the search, the phone will start scanning the available devices.
- ✅ Select your TV from the list to start mirroring.
It should be borne in mind that when you duplicate the screen, the smartphone should not go out, as this will interrupt the signal transmission, and active use of the phone while watching video can lead to a decrease in the performance of the device due to the double load on the processor and graphics chip.
Why is there a delay in sound when the screen is duplicated?
Using the Mi Remote application for management
While the main purpose of the Mi Remote app is to control your TV using an infrared port or Wi-Fi, it also provides a feature for transferring media files, which is especially true if you want to show photos or videos stored directly in your smartphone memory rather than in cloud services.
To work with local files, you need to open the application, go to the appropriate section and select the type of content. Once the devices are paired, you can view the files on the phone and display them on the TV screen, which is convenient because it does not require you to configure complex network settings.
However, if you’re streaming video from the internet, the TV’s built-in browser or the Cast feature from Chrome’s browser on your phone may be more effective. In Chrome’s Android browser, just click on the menu (three dots) and select Translate, and then select the target device.
| Method | Type of content | Dependence on the phone | Quality. |
|---|---|---|---|
| Chromecast | Online video (YouTube, etc.) | Low (used as a remote) | Maximum. |
| Miracast | The whole screen, games, photos | High (screen should be on) | Depends on the signal. |
| DLNA (Mi Video) | Local files | Medium | Original file |
Broadcast from iPhone and iPad (AirPlay)
Apple owners should not despair, as modern Xiaomi TVs support the AirPlay 2 protocol.This allows iPhone and iPad owners to broadcast the screen or video as easily as on Apple TV devices.
The broadcast launch process ("Screen Replay") is standard for the Apple ecosystem: Open the Control Point on your device (swipe down from the top right corner on new models or bottom up on old ones), click on the icon of two rectangles and select your Xiaomi Mi TV.
When you first connect, the TV can request confirmation or enter a code that will appear on the screen, a security measure that prevents unauthorized access to your screen by unauthorized devices on the shared network.
If the built-in AirPlay support doesn’t work for some reason (for example, on older TV models), you can use third-party apps from the App Store, such as Xiaomi. TV Assist or universal players of the type VLC, who can send videos over the network to DLNA-receiver.
Connection problems and their solution
Despite the simplicity of the technology, users often face a situation where the phone does not see the TV, most often the problem lies in the settings of the router. Make sure that the router does not include the "AP Isolation" feature, which prevents devices inside the network from communicating.
Another common reason is to use different frequency bands if the router is not able to properly route traffic between 2.4 GHz and 5 GHz. Ideally, both devices should be connected to the same frequency, although modern routers usually handle this automatically.
⚠️ Warning: Antivirus programs or firewalls on your smartphone can block ports needed to detect devices on your local network.
If the software methods don't work, you should try the classic but effective way to reboot. Turn off and turn on the router, the TV and the smartphone again. DNS refresh IP-addresses, which often solves problems with the visibility of devices.
💡
90% of connectivity problems are solved by checking that both devices are connected to the same Wi-Fi network, not a guest or neighbor network.
