Modern Xiaomi TVs (Mi TV) are powerful multimedia centers that allow you to not only watch broadcast television but also stream content from other devices. Using a wireless connection Wi-Fi This opens up a wide range of possibilities for the user, eliminating the need to run long HDMI cables across the room. This is especially useful when you need to quickly share a presentation with colleagues or play a high-definition movie on a large screen.
The process of connecting a computer and a TV to the same network may seem complicated only at first glance, but manufacturers have built in Mi TV The Windows operating system offers several native tools to make this task easier. In most cases, you won't need to install additional software, as the main data transfer protocols are already integrated into the system. Understanding how these technologies work will help you avoid common setup errors.
In this article, we'll take a detailed look at all available methods for streaming images, from built-in Windows features to specialized applications. You'll learn how to set up Miracast, using DLNA technology for multimedia, and the nuances that exist when working with different operating system versions. Proper setup will ensure a stable picture without lag or artifacts.
Preparatory stage and network requirements
Before you begin setting up, you need to make sure that both devices - your laptop and TV Xiaomi Mi TV - connected to the same wireless network. This is fundamental condition For most data transfer protocols, such as DLNA and Miracast, to work. If your router supports dual-band mode, it's recommended to use the 5 GHz network for high-definition video transmission, as it provides higher throughput.
Check that your TV's software is up to date. In the settings menu Mi TV Updates are frequently released that improve the stability of the Wi-Fi module and fix broadcast protocol errors. On your laptop, it's also worth making sure the wireless adapter drivers are installed correctly and are working properly.
⚠️ Attention: If your router is configured to separate networks (guest network or client isolation), devices may not be able to see each other even when in the same Wi-Fi zone. Make sure AP Isolation is not enabled in your router settings.
Wireless connection speed directly impacts image quality. A stable signal is required for comfortable viewing of 4K video or gaming. If the router is located far from the TV, the picture may stutter or the audio may become out of sync.
Screencasting via built-in Windows tools (Miracast)
Windows 10 and 11 operating systems have a built-in projection function, which is based on the standard Miracast. Televisions Mi TV Typically, this protocol is supported out of the box, allowing you to stream images with just a few clicks. This method is ideal when you need to completely duplicate or extend your desktop.
To get started, press the key combination Win + K on your laptop keyboard. The "Connect" panel will appear on the right, where the system will begin searching for available wireless displays. If the TV is online and ready to pair, its name will appear in the list.
After choosing your Mi TV If your laptop is listed, a request to allow the connection may appear on the TV screen. Use the remote control to confirm ("Allow"). The image from the laptop will instantly appear on the big screen.
☑️ Check before connection
In some cases, especially on older models or specific Android TV firmware versions, the built-in Miracast receiver may be hidden. If searching doesn't yield any results, try launching the "Wireless Display" app on your TV from the app menu or the Google Play store.
Using the Connect app on Mi TV
In the Android TV operating system, on which the Mi TV, often comes with its own pre-installed app for receiving the signal. It may be called "Broadcast," "Screen Mirroring," or "Cast." Launching this app puts the TV into standby mode, making it visible to external devices.
If the standard Windows tools don't detect your TV, opening this app on the TV may solve the problem. The app interface usually displays the device name and sometimes a QR code for quick setup. This is especially useful if automatic network detection isn't working correctly.
It's worth noting that the quality of streaming via the native Xiaomi app may vary depending on the Android TV version. Newer Google TV models have this functionality built deeper into the system, and a separate launch may not be required—simply enable streaming mode in the quick settings.
What to do if the connection is reset?
If the connection keeps dropping, try lowering the screen resolution on your laptop before reconnecting. Restarting the Wi-Fi module on your TV via the "Power Off" -> "Restart" menu, rather than simply turning it off with the remote, also helps.
For users experiencing compatibility issues, there is the option of installing alternative receivers from the Google Play Store on the TV itself, such as "AirScreen" or "Receiver for AirPlay & Cast." These programs emulate standard protocols and are often more stable than the built-in solutions.
Streaming media via DLNA and a browser
If your goal is not to duplicate your desktop, but to view movies, photos or listen to music stored on your laptop's hard drive, the technology DLNA will fit perfectly. It allows the TV Mi TV view shared folders on your computer as network storage.
To set up DLNA in Windows, open "Streaming Media Settings" from the Control Panel or search. Find your TV in the list of devices and allow it to access content. You can then open available files using any media player on your TV (such as Media Player or VLC).
| Parameter | Description | Recommendation |
|---|---|---|
| Protocol | DLNA / UPnP | Ideal for video files |
| Quality | Depends on the file bitrate | Without loss of original quality |
| PC load | Minimum | It is possible to work in parallel |
| Interface | Via the TV remote control | Convenient navigation through folders |
An alternative method is to use the built-in browser on your TV or computer. You can open the video file in the Chrome browser on your laptop, click the "Cast" menu, and select Mi TVThe browser will encode the stream and send it to the TV, which is often faster than setting up shared folders.
When streaming large files (4K HDR) via DLNA, buffering pauses may occur if the Wi-Fi signal is weak. In such cases, it's best to use a wired connection or reduce the bitrate of the file being streamed.
Third-party programs for professional broadcasting
When built-in tools are not enough, specialized utilities come to the rescue. LetsView or AirServer They allow you not only to duplicate your screen, but also to control your computer from your TV and broadcast audio with a lower latency level.
Another popular option is to use a bundle adb and streaming apps if you're an advanced user. However, for most tasks, it's enough to install the client on your PC and the server app on Mi TVFor example, the "Cast to TV" app creates a virtual display driver that optimizes video stream transmission.
Using third-party software often provides access to additional settings, such as on-the-fly bitrate, frame rate, and compression codec adjustments. This allows you to tailor image quality to your current wireless network bandwidth.
Some programs allow you to stream audio-only or video-only, which saves network resources. This is a useful feature if you want to use your TV as an external speaker or play a movie in the background.
Solution and connection optimization
Despite its apparent simplicity, a wireless connection can encounter interference. If you see artifacts or blocky images or audio out of sync, first check your Wi-Fi channel usage. Neighboring routers can create noise in the air.
Try changing the broadcast channel in your router settings to a less crowded one (e.g., 1, 6, or 11 for 2.4 GHz). For the 5 GHz band, it's best to use automatic selection or channels 36-48, which are often less noisy.
⚠️ Attention: TV operating system interfaces and firmware are regularly updated. Menu item locations and function names may differ from those described in the instructions. Always consult the latest user manual on the manufacturer's official website.
If all else fails, reset the network settings on both devices. Sometimes accumulated DNS cache errors or IP conflicts can prevent a handshake between the laptop and the computer. Mi TV.
