Modern multimedia capabilities allow you to turn any smartphone into a powerful home theater control panel. Users often wonder how to transfer an image from the screen of a mobile device to a large display to watch movies, play games or show presentations in high quality. In the Xiaomi ecosystem, this process is implemented as conveniently as possible thanks to built-in wireless data protocols.
Synchronization technologies are advancing rapidly, and today, you don't need complex cables or adapters to connect, just so that your devices are on the same local Wi-Fi network, and you can start duplicating the screen in seconds, and this opens up access to a huge amount of content that is more convenient to perceive on a large-format matrix.
In this article, we will take a look at all available broadcast methods, from standard system functions to specialized applications. You will learn about the nuances of setting up Mi TV, the features of working with iOS and Android, and how to solve typical connection problems.
The main technologies of wireless image transmission
Before you start to take action, you need to understand what technologies are at the heart of video transmission. Xiaomi smartphones and TVs support several standards, each of which has its advantages and limitations. The choice of the right protocol depends on the type of content and operating system of your gadget.
The most common standard is Miracast, which allows you to create direct Wi-Fi connection between devices without the need for a router, which is built into most Android smartphones and provides high-resolution image transfer with minimal latency, and is ideal for duplicate desktop or gaming.
The second important protocol is Google Cast (Chromecast built-in), which allows you to stream content from specific apps like YouTube or Netflix directly to your TV, in which case the smartphone acts as a remote control, and the video is buffered by the TV itself, which saves battery power on the phone.
- 📡 Miracast – full mirror display of the smartphone screen on the TV.
- 📺 Chromecast – streaming media files from supported apps.
- 📶 DLNA — transfer of multimedia content (photo, video, music) over a local network.
- 🍏 AirPlay – Apple’s proprietary protocol for iOS and macOS devices.
Also worth mentioning is DLNA technology, which is often used to play back video files stored in a phone’s memory. Unlike Miracast, it doesn’t transfer a real-time picture from the screen, but the file itself, which ensures maximum image quality without real-time compression.
Configure the broadcast through the built-in function “Translation”
The fastest way to display an image on a Xiaomi TV is to use a regular Android feature called Translation or Wireless Monitor, which requires no additional software installation and works on most modern smartphones.
To start, make sure your MI TV is on and connected to the same Wi-Fi network as your smartphone. On the TV remote, find a button with the arrow box or go to the signal source selection menu and select the option of Wireless Screen or Miracast.
On your smartphone, lower the notification curtain and look for the Translation, Smart View, or Wireless Monitor icon. If the icon is not available in quick access, go to your phone settings, Connected Devices, or Screen. After searching for available devices, select your TV from the list.
☑️ Checking before connection
Once paired, the image from the phone will appear on the big screen. It's important to note that when using this method, the orientation of the phone and the TV screen must match, or the image will stretch. For games, the best way to put the phone in horizontal mode.
⚠️ Note: When using the Translation feature, the smartphone screen must be constantly active, which can lead to rapid battery discharge and heating of the device.
Use of Mi Remote and Xiaomi Home
Xiaomi’s smart home ecosystem offers its own technology management tools that also allow you to transfer media files.The Xiaomi Home app is the central control node, but for direct screen broadcasting, an integrated utility or third-party solutions integrated through the Mi Account are more often used.
However, if you want to manage content on your phone through the TV interface, you may need to set up shared folders or use the same. DLNA-In the Mi Video (Mi Downloads) app, you can find files shared from your phone on your TV if both devices are logged in to the same Mi Cloud account.
For more advanced control, you can use the Mi Remote app, which turns your smartphone into a universal remote, and while it doesn't directly translate the image, it makes it easy to type text and navigate into your TV's menu, which is especially true if the remote is lost or discharged.
Some Xiaomi TVs with Android TVs allow you to use Google Home to create a group of devices, in which case you can stream music or video to multiple screens at once, controlling the process from a single smartphone.
Secret features of the Mi Home app
Stream from iPhone and iPad to Xiaomi TV (AirPlay)
Apple owners often face the issue of compatibility, as the AirPlay protocol is proprietary-development of the company. However, modern Xiaomi TVs based on Android TV 9.0 and higher, as well as models with the PatchWall shell, often have built-in support for AirPlay 2.
To check the connectivity, open the Control Point on your iPhone and click on the Screen Replay icon (two intersecting rectangles). If your Xiaomi TV appears on the list, it supports native AirPlay. Otherwise, you may need to install a special app on the TV itself.
For models that don't have built-in support, you need to go to the app store on your TV (Google Play Store or Mi Store) and install the AirPlay emulator app. Popular options are AirScreen or AirPin. Once installed, run the app on your TV and follow the instructions on the screen.
The connection process is as follows:
- 📱 Make sure that the iPhone and TV Connected to a single Wi-Fi network.
- 📺 Launch the AirPlay emulator app on your TV.
- 🔗 On iPhone, select the TV from the screen repeat menu».
- ✅ Confirm the connection if the code appears on the TV screen.
AirPlay transmissions are usually better than Miracast, thanks to better codec optimization, and the delay in playing games can be noticeable, but for video and photo viewing, this method is ideal.
Streaming through Google Home and Chromecast built-in
The most stable and high-quality way to view videos from the Internet is using Chromecast built-in technology. Xiaomi TVs run on Android TV, so support for this protocol is built in by default, which allows you to “send” content from your phone directly to the TV.
To use this feature, the Google Home app must be installed on your smartphone, it is necessary for initial configuration and control of the device. Once you set up the TV in the Google Home app, you can see it in the list of available devices in any application that supports broadcasting.
Open an app like YouTube, Netflix or Spotify. Find a broadcast icon (a rectangle with Wi-Fi waves in the corner). Click on it and select your Xiaomi TV. The video will play on the TV, and the phone can be used for other tasks or even turn off the screen.
| Parameter | Miracast | Chromecast | AirPlay |
|---|---|---|---|
| Type of transmission | Screen mirroring | Streaming | Mirror/Flow |
| Dependence on the phone | High (screen on fire) | Low (remote only) | Medium |
| Video quality | Depends on the signal. | Up to 4K HDR | Up to 4K HDR |
| Compatibility | Android, Windows | All LAs. | iOS, macOS |
The advantage of Chromecast is that the TV itself downloads the data stream from the Internet, without loading the processor and radio module of the smartphone. 4K-The battery of the phone can run out in an hour of active use of Miracast.
💡
If the video is slowing down when streaming via Chromecast, try to lower the picture quality in the application settings on your phone or restart the router, as the stream goes directly through the Internet channel.
Connection problems and how to solve them
Despite the simplicity of the technology, users can face various difficulties in setting up a broadcast. The most common problem is that devices cannot see each other. This is almost always due to network settings. Make sure that both the phone and the TV are connected to the same network, and not to different bands (2.4 GHz and 5 GHz), if the router separates them as different SSIDs.
Another common issue is desynchronization of sound and image or periodic twitching of the image, which indicates an unstable Wi-Fi signal. Try to bring the router closer to the TV or use a wired connection for TV, if possible. Also close background applications on your smartphone that may consume traffic.
If there is an image but no sound, check the volume settings on both devices. Sometimes the sound stays on the phone instead of switching to the TV's external speakers. In Bluetooth settings or the output on your smartphone, select the Xiaomi TV output device.
⚠️ Warning: Antivirus programs or firewalls on the router can block ports required for Miracast protocols and DLNA. Try temporarily disabling protection for inspection.
In rare cases, resetting network settings on your TV helps. Go to Settings → Device → System → Reset. Remember, this action will remove all installed apps and account settings, returning the TV to factory state.
💡
The stability of the broadcast depends on the quality of the Wi-Fi signal and the absence of interference in the air, so a dual-band router (5 GHz) is a prerequisite for comfortable viewing of 4K content.
