Today’s Xiaomi ecosystem users often face the need to display content from their smartphone to the big screen, whether it’s a family album, a work document, or an online movie that’s more convenient to watch on a 50-inch panel. Fortunately, engineers have provided wireless synchronization that eliminates unnecessary wires and adapters.
The technology is based on the standard LAN protocol that virtually all modern gadgets support, so you don't need to buy expensive equipment or have the skills of a system administrator, but you need to know a few nuances to establish a stable connection between your mobile device and your TV.
In this article, we will discuss in detail all available switching methods, from built-in system functions to third-party applications. We will discuss the features of Mi Remote, Miracast technology and the capabilities of streaming services.
Preparation of equipment and basic requirements
Before you start setting up, you need to make sure that both devices are in good condition and ready to go. The fundamental condition for successful synchronization is to find the gadget and the TV on the same local network, which means that they must be connected to the same router.
A common mistake users make is when the phone is running over a 4G/5G mobile and the TV is connected to home Wi-Fi. In this mode, detecting devices is impossible, since they are in different segments of the network. Switch your smartphone to Wi-Fi and make sure the frequencies are the same, although modern routers often combine the 2.4 GHz and 5 GHz bands into one network.
It’s also worth checking the software’s relevance. Outdated versions of firmware may contain bugs that prevent devices from shaking hands correctly. Update your TV through the settings menu, and check for updates in the About Phone section on your smartphone.
☑️ Connection readiness
Importantly, 5GHz Wi-Fi is desirable for high-resolution (4K) video transmission, providing enough bandwidth to stream heavy content without delays and image artifacts.
Use of the built-in Translation (Miracast) function
The most versatile method that works on most Xiaomi Android smartphones and TVs is wireless display technology. In MIUI and HyperOS environments, it is often called Translation or Wireless Monitor, which allows you to duplicate the phone screen on the TV in real time.
To activate the feature on the Xiaomi TV, you need to go to the main application menu and find the program “Wireless Display” or “Miracast”. Once launched, the screen will wait for the connection. On some TV models, this happens automatically when you select the appropriate signal source in the login list.
On the smartphone side, the algorithm of actions looks as follows:
- 📱 Open the notification curtain and look for the “Translation” icon (or “Cast” icon»).
- 🔍 Click on it and wait for the available devices to be found within range.
- 📺 Choose the name of your TV from the list.
- ✅ Confirm the connection if a permission request appears on the TV screen.
Keep in mind that this method does not lock your phone, you can continue to use messengers or browsers, and all actions will be displayed on the big screen, but horizontal orientation may not switch automatically, which requires manual adjustment in some applications.
What to do if the broadcast is interrupted?
⚠️ Attention: With active screen duplication, the battery consumption of the smartphone increases significantly. It is recommended to keep the device connected to the charger or use energy saving mode for background processes.
Broadcasting through the Mi Home app and ecosystem
Owners of Xiaomi equipment have the unique advantage of a deeply integrated ecosystem: Mi Home allows you to control not only smart lamps and robot vacuum cleaners, but also broadcast content, a method that is especially convenient if the standard Miracast function is unstable.
To get started, make sure the app is installed and your account is authorized. In the main interface, select your TV from the list of devices. If the TV is not displayed, click the add device button in the upper right corner and search the network.
Once you select a TV, the control panel will open in the app interface, and you're interested in the Translation button or the arrow icon, and clicking on it will trigger the search and connection process, and the advantage of this is that you can manage media files directly from the application interface.
Mi Home also allows you to stream photos and videos from the gallery without duplicating the entire screen of your smartphone, which is convenient for creating slideshows during family events, and supports a variety of file formats, including RAW and HEVC.
Using Chromecast Technology and Google Home
Many modern Xiaomi TVs are based on the Android TV operating system, which implies native support for Chromecast built-in technology. This allows you to broadcast content from partner applications (YouTube, Netflix, Spotify) without loading on the smartphone processor.
Unlike Miracast, the phone is a remote control, not a video streaming source, and the video is downloaded directly from the Internet by the TV, saving battery life and providing better picture quality, and requires a Google account and Google Home app installed to work.
The setup process looks like this:
- 📲 Open an app that supports broadcasting (e.g. YouTube).
- 📺 Click on the icon of the rectangle with waves (Chromecast) in the corner of the video.
- 🔗 Select your Xiaomi TV from the list of available devices.
- ▶️ Playback control is done from the phone, but the image goes directly to TV.
If you don’t have a built-in feature, you can use the Google Home app to broadcast the entire screen (“Translate screen”), a method that is universal and works even with devices that don’t have a Google certificate, although with some limitations on how to use the device. DRM-contention.
It is important to distinguish between Cast (stream from the Internet) and Screen Mirroring (screen mirroring), the first option is preferable for watching videos, the second is for showing presentations or games.
Comparison of Connection Methods and Their Characteristics
To make it easier for you to choose the best option, we have systematized the main ways of connecting into a single table, which will help you quickly navigate depending on your tasks and equipment model.
| Method | Image quality | Delay (Latency) | Battery consumption |
|---|---|---|---|
| Miracast | High (depends on Wi-Fi) | Medium | High-pitched |
| Chromecast | Maximum (up to 4K HDR) | Low. | Low. |
| DLNA | High. | Missing (files) | Medium. |
| HDMI (cable) | No loss. | Minimum | Charging is coming. |
As you can see from the table, the Chromecast is best suited for watching movies, as it minimizes the load on the smartphone. Miracast is indispensable for games or showing the application interface, despite its higher power consumption.
DLNA is worth mentioning separately, which does not duplicate screens, but allows you to open files from your phone on your TV through a media player (for example, VLC or built-in Mi Video), which is ideal for watching downloaded movies without converting formats.
💡
Use a router that supports Wi-Fi 5 (AC) or Wi-Fi 6 (AX) to minimize wireless latency. Older routers may not be able to handle high-resolution video streaming.
Possible problems and ways to solve them
Even if you follow all the instructions, there can be technical failures, most often the problem is network security settings or the cache of system services. If the TV can't see the phone, first try rebooting both devices and the router.
Another common reason is the enabled AP Client Isolation feature in router settings, which prevents devices within the same network from communicating with each other, and to broadcast this option, you need to turn off the admin panel of the router.
List of frequent mistakes and decisions:
- ❌ Black screen for sound: A codec problem or DRM-Try another player or method of connection.
- ❌ Lags and jerks: Weak Wi-Fi signal. Get closer to the router or switch to the 5GHz band.
- ❌ No sound: Check your Android audio output settings. Sometimes the sound stays on the phone instead of switching to TV.
⚠️ Note: Some applications (e.g., secure banking or video services) HDCP) They can block the screen for security reasons, and in such cases, the TV will have a black screen, although the interface of the phone will be visible.
If nothing helps, reset your network settings on both devices. In extreme cases, use third-party aggregator apps like Web Video Caster or AirScreen, which have their own drivers to connect to.
Additional features and subtleties of setting
Xiaomi's ecosystem offers advanced use cases, such as setting up automatic broadcast start when you turn on your TV using scripts in the Mi Home app, which turns normal browsing into a smart action.
Also worth paying attention to the setting of resolution and frame rate: In the engineering menu of the TV (available through special remotes or applications), you can force to set 1920x1080 or 3840x2160, which sometimes helps to eliminate the stretching of the image.
💡
The stability of a wireless connection depends on the quality of the router and the absence of physical obstacles between it and the devices.
Keep in mind that the software is constantly updated. Features that were not available in MIUI 12 may appear in HyperOS. Keep an eye out for system updates to access new protocols and improved stability.
