Modern Xiaomi TVs running the Android TV operating system have become full-fledged multimedia centers that require integration with other devices. Establishing a connection between a personal computer and a TV set-top box via a local network provides access to a vast array of content without the need for additional cables. A wireless connection allows you to stream high-definition video, play PC games on a large screen, and use the TV as a second monitor for work or entertainment.
The basis of such interaction is your home Wi-Fi router, which acts as a traffic manager between devices. Data transmission quality directly depends on the router's bandwidth and the stability of the signal in the room. With proper configuration, latency is minimal, and the image is transmitted without compression artifacts, which is critical for watching 4K movies.
In this article, we'll explore all available synchronization methods, from standard protocols to specialized software. You'll learn how to overcome the limitations of Android TV's built-in features and configure the system so it works seamlessly. Proper equipment preparation is key to success, so let's start with the basic requirements.
Preparing equipment and checking the network
The first step is to ensure both devices are physically connected to the same local network. Your computer and Xiaomi TV must be connected to the same router. If you're using a wired connection for your PC, make sure your router is properly assigning IP addresses via DHCP. For your TV, it's preferable to use a frequency of 5 GHz, as it provides higher data transfer rates compared to the 2.4 GHz band.
Check your network security settings. Sometimes antivirus software on your computer or strict firewall rules can block detection of new devices on the network. Make sure the network profile in Windows is set to "Private" and not "Public," which automatically allows your PC to be detected by other devices.
⚠️ Important: If your router supports the "Guest Network" feature, make sure both devices are not connected to it. Guest networks often isolate clients from each other, making data transfer between the TV and computer impossible.
It's also worth updating your TV's firmware to the latest version. Manufacturers regularly release patches that improve the stability of network modules. Wi-Fi Direct And DLNAGo to your system settings and check for updates to rule out software errors.
Mirror your Windows screen using Miracast
The easiest way to display your computer monitor on a Xiaomi TV's big screen is to use Miracast technology. This feature is built-in in Windows 10 and 11 and doesn't require any additional software. To get started, press the following key combination: Win + K on the keyboard, after which the "Connection" panel will appear on the right side of the screen.
On your Xiaomi TV, you need to launch the signal reception app. Depending on the firmware version, it may be called "Wireless Display," "Screen Mirroring," or "Cast." Once launched, the TV will go into standby mode, and its name should appear in the list of available devices on your computer.
Once connected, the image of your desktop or a specific browser window will be mirrored on the TV. This method is ideal for presentations or photo display, but may introduce a slight input lag, which is noticeable in fast-paced games. Image quality adapts automatically based on network load.
☑️ Check before connecting Miracast
Using DLNA for media streaming
Protocol DLNA (Digital Living Network Alliance) is the de facto standard for streaming media content between devices on a home network. Unlike Miracast, which broadcasts the entire screen, DLNA allows you to stream specific video, music, or photo files while maintaining playback control on your TV. In this setup, the computer acts as the server, and the Xiaomi TV acts as the renderer.
To set up the server in Windows, open "Streaming Media Settings" in the Control Panel. The system will prompt you to enable this feature and select devices allowed access. Find your Xiaomi TV in the list (it may be listed as an Android TV or by its model number) and allow it to access your libraries.
On the TV side, launch the built-in Media Player app or any third-party player with DLNA support, for example, VLC for AndroidSelect your computer in the sources menu, and you'll have access to all shared folders. This is the best way to watch movies in high bitrates without compression artifacts.
| Parameter | Miracast | DLNA | HDMI (cable) |
|---|---|---|---|
| Delay | Average | Absent | Minimum |
| Quality | Depends on the network | Original | Original |
| Control | From PC | From the TV remote control | From PC |
| Formats | Full screen | Media files | Full screen |
Why is DLNA better for 4K video?
When streaming via DLNA, the TV itself decodes the video stream using its powerful processors, whereas with Miracast, the computer compresses the image and sends the finished video stream, which puts a strain on the CPU and network.
Third-party apps for extended functionality
The built-in Android TV operating system tools sometimes become unstable or have limited functionality. To solve these problems, there are specialized applications that can be installed on both the PC and the TV. One of the most popular solutions is a combination of LocalCast or BubbleUPnP paired with desktop utilities.
Another powerful tool is the use of technology Chromecast built-in, which is built into most Xiaomi TVs. Using the Google Chrome browser on your computer, you can cast a tab or your entire desktop directly to your TV. To do this, click the three dots in the browser menu, select "Cast," and find your device.
For gamers and users who want to minimize lag, an excellent solution is the application Steam LinkIt allows you to stream games from your computer to your TV over a local network with minimal latency. Installing the app on your TV and setting up the controller takes just a few minutes, and then your PC becomes a gaming console.
⚠️ Important: When using third-party game streaming apps, make sure the H.265 (HEVC) video codec is installed on your computer if your TV supports it. This will significantly reduce network load when transmitting high-resolution images.
Don't forget about professional solutions like OBS Studio With stream output plugins, if you require complex configurations with graphics overlays before sending to a TV. However, for home use, simpler tools are usually sufficient.
Setting up access to shared folders (SMB)
Protocol SMB (Server Message Block) allows access to the computer's file system directly from the TV's file manager. This is the most reliable way to view large files, as it doesn't require on-the-fly stream conversion. In Windows 10 and 11, SMB v1 support is disabled by default for security reasons, so setting this up requires careful consideration.
First, create the folder you want to share. Right-click it, select "Properties," and go to the "Sharing" tab. Click "Advanced" and check "Share with others." Under "Permissions," ensure that "Everyone" or your specific user has read access.
On your Xiaomi TV, open a file manager (for example, File Explorer or X-plore) and go to the "Network" or "LAN" section. If the device isn't found automatically, try adding the server manually by entering your computer's IP address. When prompted for authorization, enter your Windows account login and password.
Path for manual entry: smb://192.168.1.XX/SharedFolderIt's important to note that recent Windows updates may reset access permissions for shared folders. If the connection is lost, recheck your sharing settings in the Network and Network Control Panel. Also, make sure your power settings are configured to disable turning off the hard drive to save power.
Diagnosing and troubleshooting connection problems
Even with proper setup, situations may arise where the computer doesn't see the TV or the connection constantly drops. Most often, the problem lies in the router settings or network card drivers. First, try rebooting all three components: the computer, TV, and router.
If the device is visible on the network but access is denied, check your Windows Firewall settings. The network profile may have changed to "Public" after a system update, blocking incoming connections. It's also worth checking whether your antivirus software is blocking local connections.
If you experience poor image quality or constant buffering while streaming, try lowering the stream quality or switching to a wired connection for one of your devices. The Wi-Fi signal may be unstable due to interference from nearby networks or household appliances.
⚠️ Note: Menu interfaces and item names may vary depending on the PatchWall version and the regional firmware version of your Xiaomi TV. If you don't see the option you're looking for, search for a similar one or refer to the official documentation for your model.
