Modern Xiaomi Smart TVs, running Android TV or their proprietary PatchWall interface, offer users a wide range of multimedia options. One of the most popular features is wireless image streaming, which allows you to display your desktop, photos, or videos from your computer on the big screen without the need for unnecessary cables. This transforms ordinary movie or presentation viewing into a more comfortable and high-quality experience, maximizing the TV's screen real estate.
To successfully implement this task, you don't need complex technical knowledge or expensive equipment. The entire process is based on standard data transfer protocols such as Miracast, DLNA, or Google Cast, which are already built into the TV's operating system. The main requirement is a stable connection, the nuances of which we'll discuss below.
In this article, we'll cover all available connection methods in detail, from built-in Windows tools to third-party apps. You'll learn how to set up screen mirroring, how to stream video files only, and which router settings can affect image quality. Following these instructions will help you avoid common mistakes and enjoy content without lag.
Preparing equipment and setting up the network
The first and most important step is to ensure the correct network environment. For the computer and Xiaomi TV to "see" each other, they must be on the same local network. This means both devices must be connected to the same router. If you're using a dual-band router, make sure both the PC and TV are connected to the same frequency, for example, 2.4 GHz or 5 GHz, although the 5 GHz range is preferable for transmitting high-resolution video.
Check the connection status on the TV itself. Go to the system settings and ensure that WiFi is enabled and the connection is established. For Windows computers, it's also critical that the network type is set to "Private" and not "Public." In a public profile, the security system blocks detection of other devices, making streaming impossible.
⚠️ Important: If your router separates the 2.4 GHz and 5 GHz networks into different SSIDs (network names), make sure both devices are connected to the same network. Different subnets can block direct data exchange between devices.
Transmission quality directly depends on the channel's bandwidth. If you plan to stream 4K content, poor WiFi coverage may cause artifacts or buffering. Ideally, the distance between the router and the signal receiver should be minimal, with no thick concrete walls in the way.
Mirroring Windows 10 and 11 screens using Miracast
The easiest and fastest way to display content from your computer to a Xiaomi TV is using Miracast technology, which is implemented in Windows as the "Connect" feature. This method allows for full desktop mirroring, which is convenient for sharing presentations, photo albums, or web pages. No additional software is required, as wireless display support is built into the system.
To get started, press the key combination Win + K on the keyboard. The "Connection" panel will appear on the right, where the system will begin searching for available devices. On your Xiaomi TV, you may be prompted to allow the connection; confirm this with the remote control. If the automatic search fails, make sure the "Wireless Display" app is running on your TV, which is often built into the launcher or accessible from the app drawer.
Once the connection is established, the image from your PC monitor will appear on your TV. You can choose between screen mirroring and desktop extension modes. In the latter case, your TV will act as a second monitor, allowing you to drag and drop media player or browser windows onto the TV while continuing to work on your computer in parallel.
☑️ Check before connection
Please note that when using Miracast, there may be a slight delay in the mouse cursor. This is normal for this technology, as the video stream is encoded and transmitted over the air. While this is unnoticeable for watching movies, it may not be suitable for fast-paced games.
Using Google Chromecast technology
Xiaomi TVs feature built-in support for Google Cast (Chromecast built-in). This allows you to stream content from Google Chrome browser tabs or the entire screen directly through the Google ecosystem. This method is often more stable than standard Miracast and is better optimized for video content.
To use this method, you'll need the Google Chrome browser on your computer. Open the browser, click the three dots in the upper right corner, and select "Cast." A list of available devices will appear in the menu that opens. Select your Xiaomi TV from the list.
Before starting the stream, the browser will prompt you to select a source: you can stream a specific tab, the entire desktop, or a single application window. If you select "Full Screen," your TV will display the same content as your PC monitor. This method is ideal for watching videos from websites that don't support direct casting (such as some online movie theaters).
Why is there no sound when broadcasting a tab?
If you don't hear sound when you select the "Tab" source, try switching to "Full Screen" casting or check your Windows sound settings to make sure your TV speakers or system default is selected as the default output device.
The advantage of this method is the ability to control playback from a phone or tablet, provided they are on the same network. You can start a video on your smartphone and then switch the output to the big screen, using the TV as a receiver.
Transferring media files via DLNA
If your goal isn't screen mirroring, but simply to play a video file, music, or display photos stored on your computer's hard drive, it's best to use the DLNA protocol. In this case, the TV acts as a renderer and the computer acts as a server. This reduces the load on the PC's processor and ensures smoother playback of heavy content.
Windows 10 and 11 have a built-in media server feature. Open Settings -> Network & Internet -> Status -> Sharing Options. Enable network discovery and file sharing. Then, in Streaming Media Settings, allow library access for your Xiaomi TV.
After setting up your TV, launch the Media Player app (or a similar app, such as Video Player). Select your computer from the signal sources. You'll see folders containing videos, music, and pictures. Navigation is handled using the TV remote, making it very convenient for watching movies while lying on the couch.
| Protocol | Main purpose | Delay | Quality |
|---|---|---|---|
| Miracast | Screen mirroring | Medium/High | Depends on the signal |
| Google Cast | Broadcast from a browser | Low | High (adaptive) |
| DLNA | Playing files | Absent | Original (uncompressed) |
| HDMI | Wired connection | Absent | Maximum |
It's important to note that DLNA doesn't transmit system audio or audio from other applications, only the audio contained in the file being played. Also, some video formats may not be supported by the TV's built-in player, requiring third-party software, such as VLC or Kodi.
Third-party applications and utilities
Built-in tools don't always work perfectly, especially if you have specific requirements or older operating systems. In such cases, third-party applications come to the rescue. One of the most popular solutions is LetsView or ApowerMirrorThey are available for both Windows and macOS, and have client versions for Android TV.
The principle is simple: you install the app on your computer and find it in the Google Play store on your Xiaomi TV (or use the built-in APK Installer). After launching, you need to connect both devices by scanning a QR code or entering a PIN. These apps often offer advanced features, such as mouse control with a remote control, screen recording, or drawing on a whiteboard.
Another option is to use a media center KodiThis is a powerful platform that turns your TV into a fully-fledged entertainment center. By installing Kodi on your Xiaomi TV, you can set up access to network folders (SMB) on your computer. This allows you to create a beautiful movie library with posters and descriptions by loading files directly from your PC's hard drive.
When using third-party software, pay attention to the ad resolution in free versions. Some programs may also require a paid subscription to stream in 4K resolution or remove watermarks.
Solving connection and quality issues
Even with proper setup, problems may still occur. If the TV doesn't detect your computer, try temporarily disabling your antivirus or firewall. They often block incoming connections, considering them suspicious. Restarting the router—a simple but effective method for clearing the network table cache—also helps.
If the image is choppy or broken into blocks, the problem is with the transmission channel. Try switching your router to a less congested WiFi channel. In apartment buildings, the airwaves are often clogged with signals from neighboring networks, causing interference. Using the 5 GHz band significantly reduces interference.
⚠️ Note: Xiaomi TV interfaces are subject to update. Menu item locations or app names (e.g., "Media Player" instead of "Video") may differ depending on the PatchWall or Android TV firmware version.
If your connection is constantly dropping, check if your router has speed limits for certain devices or is using "Guest Network" mode, which isolates clients from each other. For stable operation, devices must have direct access to each other within the local network.
Frequently Asked Questions (FAQ)
Is it possible to connect a computer to a Xiaomi TV via Bluetooth?
No, Bluetooth is not designed for transmitting real-time video signals due to its low bandwidth. This interface is only used for connecting peripherals such as mice, keyboards, gamepads, or audio systems.
Why is there no sound when streaming via Miracast?
Most likely, a different audio output device is selected by default in your system. Click the speaker icon in the Windows system tray, select the playback device, and select your TV or "Digital Audio (HDMI)" if the audio is coming from an adapter, or leave the PC speakers selected if the audio is being streamed separately.
Does Xiaomi support streaming from macOS without third-party software?
Xiaomi TVs don't natively support Apple's AirPlay protocol. However, since they're Android TVs, you can install an AirPlay emulator app (such as AirScreen) directly on the TV, allowing you to mirror your Mac or iPhone screen.
What is the minimum WiFi speed required for 4K video?
For comfortable viewing of 4K content without buffering, a connection speed of at least 25 Mbps is recommended. However, screen mirroring (Miracast) may require higher speeds due to the on-the-fly encoding of the video stream.
