Modern Xiaomi Smart TVs have become the standard for multimedia in the home, allowing you to display content from mobile devices and PCs on the big screen without unnecessary wires. Wireless connection Not only does it eliminate cable clutter, but it also gives you freedom to move around the room during presentations or watching movies. Windows 10 users often need to stream images, but the setup process can be challenging due to the variety of data transfer technologies.
In this article we will examine in detail all the available methods. synchronization A Xiaomi laptop and TV using only a local Wi-Fi network. We'll explore the operating system's built-in tools, third-party utilities, and native shell features. Android TV, which Xiaomi TVs are based on. You'll learn how to achieve minimal image lag and stable audio quality.
Before moving on to the technical steps, you need to make sure that both devices are in the same network environment. Network identification This is a fundamental step, without which no other method will work. If your router broadcasts signals on 2.4 GHz and 5 GHz frequencies with different names, make sure both the laptop and TV are connected to the same frequency, preferably the faster 5 GHz one.
Equipment preparation and network requirements
Successful screen sharing directly depends on the quality of the connection between devices. Technology Miracast, which is most often used for screen mirroring, is very sensitive to interference and channel bandwidth. If the router is installed far from the TV or behind a thick concrete wall, connection drops or image artifacts may occur.
It's also important to check your network settings in Windows 10 itself. The system must trust the current connection to allow discovery of other devices on the local network. To do this, go to Settings → Network and Internet → Wi-Fi and make sure the network status is set to "Private" and not "Public".
⚠️ Warning: Antivirus programs or third-party firewalls may block ports required for TV detection. If the device is not detected, try temporarily disabling network protection or adding an exception for the service. WFD (Wi-Fi Direct).
Xiaomi TVs usually open the appropriate ports automatically, but in rare cases, manual activation of signal reception mode is required. Make sure the TV isn't running any heavy apps that could monopolize the Wi-Fi channel, causing lag when streaming video from your laptop.
Miracast Method: A standard Windows 10 tool
The fastest and most reliable way to display an image is to use technology Miracast, integrated into Windows 10. This technology allows you to stream high-definition video and audio without the need to install additional software on your TV, as Wi-Fi Direct support is built into the Xiaomi firmware.
To start broadcasting, press the key combination Win + K on your laptop keyboard. The "Connection" panel will open on the right, where the system will begin searching for available wireless displays. Your Xiaomi TV should appear in the list, often labeled as Android or TV model.
☑️ Check before connecting Miracast
After selecting the device, a connection permission prompt may appear on the TV screen. Use the Xiaomi remote control to confirm ("Allow"). From this point on, the laptop screen will be cloned or extended onto the TV, depending on the projection settings you selected.
If the image quality appears blurry, check your resolution settings. Right-click on the desktop, select "Display Settings," and set the recommended resolution, which is usually 1920×1080 or 3840×2160 For 4K models. You can also select "Second Screen Only" in the "Operation Mode" menu to turn off the laptop monitor and save resources.
Broadcasting via Google Chrome browser
If the standard Windows tool does not detect the TV or works unstable, a browser is an excellent alternative Google ChromeIt has a built-in Chromecast function, which is natively supported by the Android TV operating system installed on Xiaomi TVs.
Open the Chrome browser on your laptop and click the three dots in the upper-right corner of the menu. Select "Cast" from the drop-down menu. The browser will scan the network and find your TV. You can choose to cast a specific tab, the entire desktop, or play a media file.
| Parameter | Description | Recommendation |
|---|---|---|
| Tab | Broadcast the contents of one browser tab | Ideal for videos from websites |
| Full screen | Cloning the entire Windows desktop | For presentations and software demonstrations |
| File | Playing a local video file | Supports fewer formats |
It's important to note that streaming through Chrome places a significant load on your laptop's processor, as it encodes the video stream. This can lead to increased power consumption and heat buildup. Make sure your laptop is plugged in for extended sessions.
Using DLNA to play files
If your goal is not screen mirroring, but watching movies or listening to music stored on your laptop's hard drive, the best technology to use is DLNAIt allows the Xiaomi TV to view shared computer folders as network storage.
In Windows 10, this feature is implemented through "Media Streaming Settings." Go to "Control Panel" → "Network and Internet" → "Network and Sharing Center." On the left, select "Media Streaming Settings" and click "Enable." Find your Xiaomi TV in the list of devices and allow it to access content.
After setting up your Xiaomi TV, launch the Media Player app (or a similar app, such as VLC or MX Player, if the built-in player doesn't detect the network). Select your computer from the signal sources. The folder structure will be displayed on the TV screen, and you can launch files directly using the remote control.
⚠️ Please note: DLNA technology does not support streaming Windows system sounds or sounds from applications other than the media file being played. System sound effects will remain on the laptop.
Third-party apps and AirPlay
Apple device owners or users seeking advanced functionality can use third-party solutions. Xiaomi TVs support the protocol. AirPlay 2 natively in the latest firmware versions, allowing MacBook or iPhone owners to connect without any extra software.
For Windows users, there are emulator apps such as AirServer or LetsView. These are installed directly on a Xiaomi TV via the Google Play store. Once installed, the app turns the TV into a universal receiver that supports Miracast, AirPlay, and Google Cast protocols simultaneously, often with better picture quality.
Installing such apps may require more RAM on your TV. If the Xiaomi TV interface starts to lag, close background apps in the running tasks menu. This will free up resources for processing high-resolution video streams.
Why might AirPlay not work on Windows?
Native AirPlay is designed for the Apple ecosystem. On Windows, it only works through third-party TV receivers or emulators, which may be paid or contain ads.
Diagnosing and troubleshooting connection problems
Despite the simplicity of the technology, glitches sometimes occur. If your TV doesn't appear in the list of available devices, first try rebooting your router. DNS cache or temporary router errors often block device detection on the local network.
Check the wireless adapter drivers on your laptop. Go to Device Manager (click Win + X and select the option), find your network adapters. If there's a yellow exclamation mark next to your Wi-Fi module's name, you need to update the driver through the laptop manufacturer's website.
It's also worth paying attention to the power-saving settings of your Wi-Fi adapter. In the adapter's properties in Device Manager, go to the "Power Management" tab and uncheck "Allow the computer to turn off this device to save power." This will prevent the connection from dropping when idle.
⚠️ Note: The MIUI TV interface is updated regularly. The location of network settings or menu item names may differ depending on the firmware version of your Xiaomi TV. Please check the current paths in your device's settings menu.
Frequently Asked Questions (FAQ)
Is it possible to connect a laptop to Xiaomi TV without a router?
Yes, this is possible using Wi-Fi Direct technology, which is the foundation of Miracast. Devices connect directly to each other, creating their own network. However, the initial handshake sometimes still requires an access point, or you need to use the smartphone's "Access Point" mode as an intermediary.
Why is there a sound delay when connecting via Wi-Fi?
Lag is often caused by wireless channel congestion or a slow TV processor when decoding the stream. Try switching your router to a 5 GHz channel, closing unnecessary programs on your laptop, or using DLNA for video files instead of screen mirroring.
Does Xiaomi TV support 5.1 sound when connected via Wi-Fi?
The Miracast protocol theoretically supports multichannel audio, but in practice, Windows often downmixes it to stereo (2.0) during wireless transmission. For full 5.1 or 7.1 surround sound, an HDMI cable or optical output is preferable if audio quality is critical.
How to disconnect a laptop from a TV?
The easiest way is to press a combination Win + K and select "Disable" from the menu that appears. You can also click Win + P and select "Computer screen only." In the Chrome app, simply tap the casting icon and select "Stop."
