Modern users rarely limit themselves to viewing content exclusively through built-in smart TV apps. Often, there is a need to display a presentation from a laptop, photos from a smartphone gallery, or even launch a game from a mobile device. Xiaomi owners often wonder how to activate this feature, since menus can vary depending on the version of the operating system. The process of streaming images, or screencasting, has become the de facto standard for multimedia systems.
In this article, we will take a closer look at all the available ways to connect external devices to a Xiaomi Mi TV. We will look at native Android TV features, the capabilities of the Google Home ecosystem, as well as specific settings for models with a MIUI for TV shell. Understanding the differences between Miracast and Chromecast protocols will help you avoid problems with image latency or lack of sound.
Before you start setting up, make sure that both the TV and the signal source (smartphone or PC) are connected to the same Wi-Fi network. This is a critical condition without which wireless data transmission over the local network is impossible. If the router distributes a guest network or uses client isolation, the connection will not be possible.
Use of the built-in wireless display function
Most modern Xiaomi TVs are based on Android TV or its modifications, and these systems already support wireless media transfer technology. You don't need to install additional applications on the TV itself, just activate the appropriate mode in the settings. This feature is usually called "Wireless display" or "Screen Mirroring".
To activate mode on the remote, press the menu button or go to the settings section. Find the connection and networking item. In some versions of the firmware, it may be in the About TV or Display and Sound section. Once the mode is turned on, the TV goes to the standby state, becoming visible to other devices.
The menu interface may look different depending on the model’s year of release. On older versions of MIUI TV, the path to settings may be different from the current Android TV 11 or Google TV. If you can’t find the item you want, try using voice search on the remote by saying “Wireless display.”
⚠️ Warning: In mirror mode, the screen of the smartphone is fully copied to the TV, which means that all notifications, incoming calls and messages will be visible to everyone in the room.
Connecting Android smartphones via Chromecast
For Android smartphone owners, the most convenient and stable way is to use Google Chromecast built-in technology. This feature is built into most applications such as YouTube, Netflix, Twitch and Google Chrome. Unlike full screen mirroring, only the video stream is broadcast here, allowing you to use the phone for other tasks without interrupting playback.
To start streaming, open the supported app on your smartphone. At the top or bottom of the interface, find the rectangle icon with the waves in the corner - this is the standard Cast symbol. Click on it and select from the list your Xiaomi Mi TV. If the device is not found, check if Bluetooth is on on the smartphone, as it is used for initial detection.
- 📱 Make sure the app is updated to the latest version through the Google Play Store.
- 📶 Check that your smartphone and TV are in the same Wi-Fi subnet (2.4 GHz or 5 GHz).
- 🔄 Restart your router if the list of available devices is empty.
The quality of the transmitted image depends on the speed of the wireless connection. To view video in 4K HDR resolution, it is recommended to use a 5 GHz network, since the 2.4 GHz standard may not provide sufficient bandwidth. If you have buffering, try to bring the router closer to the TV or reduce the picture quality in the application settings.
💡
If you try to connect through Chromecast, try Google Home to find your TV and select "Translate screen" and this will force you to start mirroring mode.
Broadcast from iPhone and iPad (AirPlay)
Users of the Apple ecosystem may be struggling because native support for AirPlay 2 is not available on all Xiaomi TVs. However, many new models have already received this feature through software. If your TV supports AirPlay, you will see the corresponding icon in the iOS control center or in the Screen Replay menu.
If there is no built-in support, Apple may offer to install a third-party app on the TV. Popular solutions like AirScreen or AirPin are available in the Google Play store on the TV itself. Once installed, the TV emulates the AirPlay receiver, allowing content to be streamed from an iPhone, iPad or Mac without using cables.
The process of setting up a third-party emulator is simple: run the application on the TV, wait for the appearance QR-Then on your iPhone, open Control Point, press Screen Replay, and select the device that appears. The latency may be slightly higher than when you're connecting natively, but it's not critical to view photos and videos.
| Type of device | Recommended protocol | Required TV app | Quality. |
|---|---|---|---|
| Android smartphone | Chromecast / Miracast | Not required | High. |
| iPhone / iPad | AirPlay 2 | Depends on the TV model. | High. |
| Windows PC | Miracast | Not required | Average. |
| MacBook | AirPlay | AirScreen (optional) | High. |
Demonstrate screen from computer on Windows
Windows 10 and 11 have a built-in projection function that works on the Miracast protocol, which allows you to display your desktop, browser window or game to the big screen without buying additional adapters.
To connect, press the Win + K keyboard on your computer. The Connect panel will appear on the right. Your TV should be displayed on the list of available devices. If the TV is not visible, make sure it has the wireless display feature mentioned in the first section.
☑️ Checking before connecting the PC
Once you have a successful connection, you can choose to use the projector mode, and you can use the options: duplicate screen (a copy of the desktop), extension (the TV becomes the second monitor), or only the second screen (the main monitor goes out), or the best way to view the video is to use the duplication mode or only the second screen to avoid dissynchronizing the mouse cursor.
⚠️ Attention: When streaming heavy games or high-resolution video from PCs, there may be a noticeable input lag. For dynamic shooters, this method is not recommended, use a cable. HDMI.
Setup via Mi Remote and Xiaomi Home
Xiaomi’s smart home ecosystem offers its own content management tools. Xiaomi Home (or Mi Home) app lets you not only control robot vacuum cleaners and lamps, but also stream media files to your TV, which is especially handy if you want to show photos taken with your smartphone camera right after you shoot.
The app needs to add a TV to the list of devices if it hasn't been done before. Once authorized, select your TV from the list. The management interface often has a Translation button or cast icon that lets you select a file from the phone gallery or run streaming video from the clipboard.
Also worth mentioning is the Mi Remote app, which turns a smartphone into a remote, and although its primary function is to control navigation, in some versions it allows you to open links on your TV. Just copy a link to a video on your smartphone, and the TV will prompt you to open it through your built-in browser or player.
The Secret Debugging Function
Solution: Connection and sound problems
Despite the simplicity of the technology, users often face a situation where devices "can't see" each other. The most common reason is using different Wi-Fi frequencies. If a router distributes 2.4 GHz and 5 GHz networks with different names (SSID), make sure that both the phone and the TV are connected to the same network. Different frequencies within the same SSID usually do not cause problems, but isolating customers in the router settings can block the connection.
Another common problem is the lack of sound when you broadcast a successful image, which is often the case when you connect to Miracast with Windows, and then you go to the audio settings on your computer, select the output device, and switch it from the speakers to the TV speaker, and sometimes it helps to simply change the volume on the TV remote, which "wakes up" the audio channel.
- 🔇 Check if the TV is in "Video Only" mode in the settings of the Windows projector.
- 🔌 Rebooting the router solves 90% of device detection problems.
- 🛡️ Antivirus on PCs can block protocols DLNA Miracast and try to temporarily disable the protection.
If the image twitches or has a low resolution, check the load on the Wi-Fi channel. Downloading large files on other devices can "clog" the air. LAN-cable, if the model supports this capability, or use the 5 GHz band.
💡
The stability of wireless broadcasting is 80% dependent on the quality of the Wi-Fi signal and the absence of interference in the air, not on the power of the TV itself.
