Xiaomi’s modern Smart TVs have become the hub of multimedia entertainment in most homes, providing access to a huge amount of content through the Android TV platform or PatchWall’s own shell. However, the capabilities of embedded apps are sometimes not enough, and users often face the need to bring to the big screen the contents of their smartphone, tablet or laptop. This can be a presentation, family photos, videos from a non-core application or even a mobile game that is more convenient to play on a large display.
The process of streaming images, often called screencasting or mirroring, is flexible enough on Xiaomi devices to require the right setup of both devices. Unlike simple share buttons, full screen duplication requires stable connection and understanding the differences between data protocols. In this article, we will discuss in detail all the ways of connecting, from standard system functions to advanced methods for various operating systems.
It is important to understand that image quality and latency are directly dependent on the bandwidth of your Wi-Fi network. Before you start setting up, make sure that your TV and mobile device are on the same LAN, as this is a fundamental requirement for most wireless video streaming methods. Ignoring this rule is the most common reason why devices don’t “see” each other.
Equipment preparation and network requirements
The first step before activating the Mi Cast function or any other mirroring protocol is to thoroughly check the network infrastructure. Xiaomi TVs running on Android use standard wireless protocols that can conflict if the router is not configured correctly. Make sure your broadcast device and receiving device (TV) are connected to the same access point, whether it is the main 2.4 GHz band or the higher 5 GHz speed band.
Special attention should be paid to customer isolation settings on your router. This security feature, often turned on by default on guest networks, prevents devices within the same network from communicating with each other, making it impossible for a smartphone to detect a TV. If you use guest Wi-Fi mode, you need to either turn off customer isolation in the router settings or reconnect both devices to the main network.
It’s also worth checking the software’s relevance. On your TV, go to Settings → About TV → System Update and make sure you have the latest version of MIUI for TV or PatchWall installed.Outdated Wi-Fi module drivers can malfunction with new versions of smartphone operating systems, causing connection breaks or no image.
⚠️ Note: Used Wi-Fi networks (in cafes, hotels, airports) to duplicate screens are often impossible due to strict traffic separation.
Use the built-in Mi Cast feature on the TV
Xiaomi’s TV operating system pre-installed Mi Cast, which is similar to Miracast technology, which allows you to stream the screen without having to install additional apps on the receiving side, which greatly simplifies the process. To activate, you need to find the corresponding application in the main menu or in the Apps folder on the TV desktop.
When you start the Mi Cast app, you'll have a wait for the TV to connect, and in this mode, the TV creates a special channel to receive the video stream. On some PatchWall TVs, the function can be built directly into the Quick Access menu, which is called by a gear button or a separate button on the remote.
The quality of the image being transmitted in Mi Cast mode depends on the Wi-Fi power of your router's module. If you see a picture layering or jerking, try bringing the router closer to the TV or using the 5GHz band, which is less crowded and provides higher data rates. The Miracast standard underlying this feature is sensitive to interference.
☑️ Checking before launching the Mi Cast
It's worth noting that when you connect through Mi Cast, the sound is also transmitted to the TV, and the phone can be used as a remote control, but if you fold the broadcast app on the phone, the video may stop streaming, as it is a mirror image, not a background streaming.
Broadcast from Android-smartphones
Android smartphone owners have several ways to connect to a Xiaomi TV, and the choice of the specific method depends on the manufacturer of your phone. In most modern devices, the feature is called Translation, Smart View, Wireless Monitor or Projection, and you can find it in the notification curtain (swipe down) or in the screen settings.
When you activate a device search on your smartphone, it will start scanning the network for available receivers that support Miracast or Chromecast built-in. Once your Xiaomi TV appears on the list, just click on it. The system will request confirmation on the TV screen - agree to the connection using the remote.
If you don't have a standard connection, you can use Google Home, a universal tool from Google that allows you to manage Chromecast-enabled devices. Install the app, find your TV on the list of devices, and click Translate screen, a method that often works more stable than the built-in features of smartphone manufacturers.
| Smartphone manufacturer | Name of function | Location on the menu | Features |
|---|---|---|---|
| Xiaomi / Redmi / POCO | Broadcasting | Control Center / Settings | Native support for Mi Cast |
| Samsung | Smart View | Notification curtain | High stability, 4K support |
| Huawei / Honor | projection | Notification curtain | Desktop mode for some models |
| Pure Android | Broadcasting | Settings → Connected devices | Requires Google Home App |
⚠️ Note: When broadcasting from an Android smartphone, notifications (messages, calls) will be displayed on the TV screen. It is recommended to turn on the "Do Not Disturb" or "Game Mode" mode in advance so as not to interrupt the viewing of private messages.
Duplication of screen with iPhone and iPad (iOS)
Apple devices use the proprietary AirPlay protocol, which is not originally supported by Android TVs out of the box. However, Xiaomi has implemented AirPlay 2 support in most of its modern models, allowing iPhone and iPad owners to stream content without buying the expensive Apple TV console.
To get started, make sure your TV has AirPlay support on. Go to your TV settings, find the section related to external connections or Apple AirPlay, and activate this option. Then you open the "Control Point" on your iPhone (swipe down from the top right corner on new models or swipe up on models with a button).
Click on the Screen Replay icon (two rectangles) and select your Xiaomi TV from the list. If the access code is not requested, the image will appear almost instantly. AirPlay protocol provides high stability and allows you to use the phone in parallel with watching video, since the broadcast is on the server level, rather than just copying the picture.
What if AirPlay doesn’t work on Xiaomi?
Image quality through AirPlay is usually better than through Miracast, due to better compression of the video stream. However, it is worth considering that when you use the phone actively during the broadcast (for example, running a heavy game), performance may fall, as the processor will be loaded with both the rendering of the interface and encoding the video stream.
Broadcast from laptop to Windows and macOS
For Windows 10 and 11 laptops, the process of connecting to Xiaomi TVs is as simple as possible thanks to the integration of Miracast technology into the core system. You don't need to install any drivers, just press the Win + K keyboard combination. On the right side of the screen, the Connect panel will appear, where your TV should be displayed.
If your computer can't find the TV, check your projection settings. Press Win + P and select Connect to Wireless Display mode. Also make sure that the Windows settings in System → Project on this computer have detection permissions. The TV must be in standby mode (Mi Cast is open).
MacOS users are less fortunate because Apple does not provide native Miracast support. There are two ways for them: using Google Chrome with an extension for casting or installing third-party software on a TV. The easiest way is to open the Chrome browser on a Mac, click the menu (three dots) → Save and Share → Translate, and select a tab or desktop.
💡
To reduce latency when broadcasting from your laptop, close the background programs consuming traffic (torrents, cloud synchronization) to free up the Wi-Fi channel for the video stream.
Solving problems with delays and image quality
One of the most common problems with screen duplication is the desynchronization of audio and video or the appearance of compression artifacts. This often happens because of radio congestion. If your router is running at 2.4 GHz, it can be affected by microwave ovens, Bluetooth devices and neighboring Wi-Fi networks. Switching to 5 GHz solves 90% of these problems.
Another reason for delays (input lag) can be the image processing on the TV. Modes "Movie", "Dynamic" often add post-processing, which causes a delay. Switch the picture to "Game" or "Monitor" mode through the settings of the TV image to minimize signal processing and speed up response.
If the image is constantly interrupted, try to lower the output resolution on the mobile device, if such an option is available. Also an effective method is to restart the router, since long periods of operation without turning off lead to filling memory buffers and reduced performance of network equipment.
💡
The stability of the connection depends on the quality of the Wi-Fi signal and the absence of interference in the air, not on the power of the TV itself.
