Modern Smart TVs from the Xiaomi brand have a wide functionality that allows you to turn the living room into a full-fledged multimedia center. One of the most popular features is the ability to duplicate images from a smartphone or tablet to a large display. This is convenient for viewing photos, showing presentations or running games from a mobile device. The setup process does not require deep technical knowledge, but has its own nuances depending on the operating system of your gadget.
Wireless video technology works well when both devices are connected to the same router. In the Android and iOS ecosystem, there are built-in tools and third-party solutions that help to establish communication. Wireless connectivity provides usability, eliminating unnecessary wires and distance restrictions. However, for a quality picture without delay, it is important to consider the power of the Wi-Fi signal.
In this article, we will discuss in detail all the available ways to replay the screen on a Xiaomi TV using standard system tools and popular applications. You will learn how Miracast protocol differs from Chromecast technology, and how to solve typical problems with finding a device.
Preparation of equipment and network
Before you start setting up, you need to make sure your equipment is ready to go. The first and most important condition is to connect your Xiaomi Mi TV and smartphone to the same Wi-Fi network. If one device is connected via the mobile Internet (4G/5G) and the other via a home router, they will not see each other on the list of available devices.
It's also worth checking the software's relevance. Manufacturers regularly release updates that improve the stability of the communication modules. Go to the TV menu, select Settings, then go to About System and check for updates. A similar procedure is recommended on a mobile device.
⚠️ Note: Using a guest Wi-Fi network may block interaction between devices due to customer isolation settings.Make sure both gadgets are on the main network.
To ensure maximum data speed, it is advisable to use the 5 GHz band if your router and TV support this frequency. This is especially true when streaming video in high resolution 4K or Full HD. In the 2.4 GHz band, interference from neighboring networks and household appliances is possible, which will lead to twitching of the picture.
Use of the built-in Miracast feature on Android
The Android operating system, which is installed on most smartphones, has built-in support for Miracast technology. Xiaomi TVs also have a module for receiving such a signal. The name of the feature on different phones may vary: “Translation”, “Wireless Monitor”, “Smart View” or “Screen Replay”.
To start the process, open the notification curtain on your smartphone and find the corresponding icon. If it is not available in quick access, go to Settings → Connections → Broadcast. Once you turn on the search, the phone will start scanning available devices. Your Xiaomi TV should appear in the list.
☑️ Pre-broadcast checks
Once you select a TV, you may see a request for confirmation of connection. Use the remote to receive the request. The image from the phone will instantly appear on the big screen.
To stop broadcasting, just click on the function icon in the notification curtain again or select "Disable" from the TV menu. The picture quality depends on the power of the Wi-Fi signal. If you notice the desynchronization of sound and video, try to approach the router.
Broadcasting via Google Chromecast
Many Xiaomi TVs are powered by Android TV or have built-in support for Google Cast technology, which allows content to be streamed not by mirroring the entire screen, but by directly transferring the video stream from the app to the TV, a method that is more energy efficient for the smartphone and provides better image quality.
To use this feature, make sure your phone has a Google Home app installed. Open it and find your TV in the device list. Click on the device icon, then select the Broadcast button. The system will prompt you to start streaming, after which the contents of the phone's display will appear on the TV.
The advantage of the Chromecast is that you can control playback from your phone while the TV plays content on its own. You can fold the app, respond to a message, or even turn off the smartphone screen, and the video on the TV will continue to go. This is convenient for watching movies from online cinemas.
⚠️ Note: Some applications protect content from copying (DRM). When you try to broadcast protected video through a mirror display, the screen can turn black, only sound will be heard.
Screen duplication applications
If standard methods don’t work or require advanced functionality, you can use third-party programs. There are a wide range of streaming utilities available in the Google Play Market or App Store, and AirScreen, TV Cast and LocalCast are popular solutions.
To install the app on your Xiaomi TV, go to the Google Play app store directly on your TV or use the built-in search. Find the right app, like AirScreen, and install it. Once launched, the app will create a virtual device that will be visible to your smartphone.
| Title of the annex | Platform | Features | Advertising |
|---|---|---|---|
| AirScreen | Android / iOS | Support for AirPlay, Miracast, Google Cast | It's in the free version. |
| TV Cast | Android / iOS | Broadcasting video from the browser | Present. |
| LocalCast | Android | Working with local files | Minimum |
| ApowerMirror | Android / iOS | High quality, management with PC | Limited trial period |
Using third-party software allows you to broadcast content from iOS devices to Android TV, Because AirPlay is not natively supported on all TVs, follow the on-screen instructions to pair devices once you install the app. QR-code or enter a digital code.
💡
If the app on the TV is unstable, try restarting the router. This will clear the network clipboard and highlight a new one. IP-address, which often solves the problem of communication interruptions.
Connection through HDMI-cable
When wireless connectivity is not possible or maximum stability is required (for example, for games with minimal input delay), a wired connection will be the best choice. HDMI TV-free.
For smartphones with a Type-C port, you will need a Type-C to HDMI adapter. Make sure your phone supports MHL or DisplayPort Alt Mode technology, otherwise there will be no signal transmission. Connect the adapter to the phone and an HDMI cable to it, the second end of which is inserted into the TV port.
After the physical connection, take the remote from the Xiaomi TV and click the signal source select button (usually marked as Input or the arrow square icon). In the menu that appears, select the corresponding HDMI port 1, HDMI 2, etc. The image should appear automatically.
Why isn't there an HDMI signal?
The advantage of wired technology is that it doesn't have latency and is independent of Internet speed, you can play dynamic games or work with presentations without fear of the image floating because of interference in the air, and it doesn't drain as quickly as it can get power from the network via an adapter.
Decision and delays
Despite the ease of setting up, users may face a variety of problems, and the TV is not visible in the list of available devices, in which case you should check whether the router has activated AP Isolation, which prevents devices within the network from communicating.
Another common problem is desynchronization of sound and image, which often happens with a weak Wi-Fi signal or high load of the channel by neighboring devices, try switching to the 5 GHz band or disabling downloads on other devices on the network.
⚠️ Warning: If the phone's screen goes out during broadcast, check the power saving settings.The system can force the Wi-Fi module to shut down to save battery power.
You can use built-in network tools to diagnose problems. On a Xiaomi TV, go to Settings → Network and check the connection quality. If the speed is below 10 Mbps, stable high-quality broadcasting is not possible. In such cases, it is recommended to lower the broadcast resolution in the application settings.
💡
The stability of the connection depends on the distance to the router and the number of obstacles (walls) between it and the TV.
