How to bring the laptop screen to the Xiaomi TV via Wi-Fi

Modern technology allows you to turn the living room into a real multimedia center, where content from a small laptop screen is instantly transferred to a large panel of Xiaomi TV. This is especially true for watching high-resolution movies, holding presentations or showing photos to friends without the need to use unnecessary wires. Wi-Fi connection provides sufficient bandwidth to transmit a quality video stream, saving the user from confusion with HDMI cables.

However, the setup process can vary depending on your computer’s operating system and the firmware version of your TV. Mi TV and Android TV owners often face the need to choose the right broadcast protocol, whether it’s standard Miracast, Google Cast technology or third-party applications. Understanding the differences between these methods will help avoid image delays and sound dissynchronization.

In this article, we will discuss all the available ways of connecting, paying special attention to the nuances of working in Windows and macOS. You will learn how to configure the network correctly to ensure stable data transfer, and what to do if devices do not see each other.

Preparatory stage and network requirements

Before you start setting up, make sure that both your laptop and your Xiaomi TV are connected to the same wireless network.This is a fundamental requirement for most media protocols. If your router supports dual-band, it is highly advisable to use a 5GHz network, as it provides faster data transfer speeds and lower latency compared to the 2.4GHz band.

Check the software on your TV. Go to Settings → About TV → System Update and make sure you have the latest version of MIUI for TV or Android TV OS installed. Outdated Wi-Fi module drivers can cause unstable connection or no visibility of the device in the list of available displays.

Also worth paying attention to the power saving settings of the network adapter in the laptop operating system. Windows can sometimes turn off the module to save energy, which leads to a connection break during browsing. Open Device Manager → Network Adapters, find your Wi-Fi module, go to properties and on the Power Management tab uncheck the "Allow disconnect this device".

Broadcasting through the built-in Windows function (Miracast)

Windows 10 and 11 have built-in support for Miracast technology, which allows you to duplicate the screen without installing additional software. Xiaomi TVs with the Android TV shell usually support this protocol out of the box. To start the broadcast, click the Win + K keyboard on the laptop keyboard. On the right, the Connect panel will open, where the system will begin to search for available displays.

If the TV doesn't appear on the list right away, it may need to activate the reception mode. Mi Remote remotes often have a separate button to select the source of the signal or launch the Wireless Display application. In some versions of MIUI TV firmware, you need to manually run the Miracast or Wireless Display application through the application menu.

⚠️ Note: When using Miracast, the image is transmitted directly from the laptop graphics card, which can increase the load on the processor and battery.

Once paired successfully, you can choose between a backup screen or a desktop extension. Expansion mode is useful if you want to use the TV as a second monitor to host the video player, leaving the main screen free to work with documents. Picture quality in this mode is usually high, but may depend on the power of your Wi-Fi router.

Using Google Chromecast technology

Because many Xiaomi TVs run on Android TV, they have built-in support for Google Cast technology.This is one of the most stable ways to stream content from Google Chrome or the entire screen. Make sure your laptop has a Chrome browser and a Google Home extension (although the browser itself is often enough).

Open the Chrome browser, click on the three dots in the top right corner and select "Cast." From the menu that opens, select "Cast desktop" if you want to show all the windows, or "Translate tab" for a particular site. From the list of devices, find the name of your Xiaomi TV.

The advantage of this method is stream optimization: the TV decolates the video stream itself, which reduces the load on the laptop. However, the desktop (not the browser) still uses a resource-intensive method of screen capture. For macOS users, this method is also the main one, since native Miracast support is absent at Apple.

Broadcasting from macOS via AirPlay and third-party solutions

Owners of MacBook laptops will have to use additional funds, since the native AirPlay protocol is not supported by all models of Xiaomi TVs directly. If your Mi TV model is certified by Apple AirPlay 2 (usually new models with Android TV 9.0+), then simply select the TV in the “Screen Replay” option in the macOS menu.

If you don't have native AirPlay support, the best solution is to install a remulator application on your TV, such as AirScreen or Receiver for AirPlay. Once you install it on your TV, your laptop will see it as a standard Apple device. Run the app on your TV, then on your Mac, press Control Center → Screen Repair and select the device you find.

Alternatively, you can use the Chrome browser with the Cast feature described above, or install specialized software like AirParrot on your computer, which allows you to broadcast the screen with minimal latency, but require you to buy a license for full functionality. Free analogues can have session time limits or watermarks.

Comparison of Connection Methods and Their Characteristics

The best way to choose depends on your goals: for gaming, minimal latency is important, and for watching movies, stability and picture quality. Below is a comparative table of the main methods available for linking a Xiaomi laptop TV.

Note that when using high-compression video stream techniques (such as some Miracast implementations at a weak signal) compression artifacts may occur. For fast-moving games, a wireless connection can give a noticeable input delay, so gamers are advised to use an HDMI cable or specialized game modes.

If you plan to use your TV as a second monitor for text, any wireless method is great, but for color (design, photo retouching), Wi-Fi calibration can be inaccurate because of the way the TV processor processes the image.

💡

For office work and video, Google Cast or Miracast is best, whereas for dynamic gaming, wireless methods can give a noticeable delay.

Troubleshooting and typical errors

The most common problem is that the TV doesn't show up on the list of available devices, and 90 percent of the time it's because the devices are on different subnets, for example, if the router distributes the Guest Network, it can block communication between devices within the LAN, and make sure that both are connected to the main network.

Another reason could be the firewall or antivirus settings on your laptop, which can block incoming connections needed to shake hands with the protocol, try temporarily disabling the antivirus or adding an exclusion rule for Projector or Chrome.

⚠️ Attention: If the image twitches or crumbles into squares, try lowering the output resolution or bringing the laptop closer to the router. an overloaded Wi-Fi channel can also cause instability.

Network resets can be helpful in some cases. On a Xiaomi TV, you can do this via Settings → Network → Reset Network settings. On Windows, the command netsh winsock reset in the command prompt (launched on behalf of the administrator) often solves problems with network drivers.

💡

Reboot the router before setting up. This will clear the cache. DHCP and give out fresh IP-Addresses to devices that often solve visibility problems.
