Modern televisions Xiaomi Mi TV Android TV and set-top boxes offer users a wide range of multimedia options, allowing them to display images from their PC without the need for bulky HDMI cables. Wireless data transfer has become a de facto standard, providing flexibility in setting up a home theater or workspace. To implement this feature, owners don't need complex equipment; a stable connection is sufficient. Wi-Fi connections and basic knowledge of network protocols.
In this article, we'll cover all the current methods for mirroring your computer screen to a Xiaomi TV via Wi-Fi, including built-in Windows features, third-party utilities, and specific router settings. You'll also learn about the protocol nuances. Miracast And DLNA, which often cause confusion for beginners. Proper network configuration will allow you to enjoy high-definition content without lag.
Before you begin setting up, make sure both devices are on the same local network. This fundamental requirement for most wireless video streaming methods. If your router broadcasts two networks (2.4 GHz and 5 GHz), it's advisable to connect both the PC and TV to one of them, preferably the faster one. 5 GHzto minimize buffering.
Preparation of equipment and network infrastructure
The quality of wireless streaming directly depends on the bandwidth of your home network and the distance between devices. TVs Xiaomi are typically equipped with dual-band Wi-Fi modules, which allow for the use of less crowded frequency bands. The computer must also support the standards Wi-Fi Direct or have a built-in adapter compatible with broadcast protocols.
To check your current connection speed and signal stability, you can use the operating system's built-in diagnostic tools. In Windows, this is done via the command line, where you enter commands to analyze the wireless adapter's status. A weak signal can cause image artifacts and audio desynchronization.
It's important to note that some corporate or public Wi-Fi networks may block direct connections between devices (client-to-client) for security reasons. In such cases, streaming will be impossible without changing router settings or using a guest network. Home routers typically don't have such restrictions by default.
Broadcasting via built-in Windows functionality (Miracast)
Operating systems of the Windows family (10 and 11) have built-in support for the technology Miracast, which allows you to broadcast your screen without installing additional software. TVs Xiaomi TVs with the PatchWall shell or pure Android TV also support this standard, often referred to as "Wireless Display" or "Screen Mirroring." To get started, you need to activate the signal reception on your TV.
On your TV remote control, locate the source menu button or go to the apps section. You'll need to find and launch the app. Wireless Display, Miracast or something similar, depending on the regional firmware. After launching, a message will appear on the screen indicating that a connection is pending, and the device will become discoverable.
☑️ Windows to Xiaomi TV connection algorithm
On your computer, press the key combination Win + Kto open the connection panel. Your TV should appear in the list of available devices that appears. XiaomiClick it, and the system will attempt to establish a connection. If successful, your computer screen will be mirrored on the larger display.

In some cases, you may need to change the projection mode. The system will offer options: "Duplicate," "Extend," or "Second Screen Only." Mode Expand Turns your TV into an additional monitor, making it convenient for working with documents or watching videos in a player window without occupying the main monitor.
Using Google Chromecast technology
Because televisions Xiaomi are based on Android TV and have built-in support for the technology. Google Cast (Chromecast). This is one of the most stable ways to stream content, especially from the Google Chrome browser. Unlike Miracast, it uses the DLNA protocol and Google's own servers for streaming, which often results in a better picture.
First, make sure Google Chrome is installed and updated on your computer. Open the browser and click the three dots in the upper right corner, then select "Cast." The system will automatically scan the network for available Chromecast devices.
| Parameter | Miracast | Google Cast | DLNA |
|---|---|---|---|
| Signal source | Windows video driver | Browser / Application | Media player |
| Latency | Low / Medium | Average | Absent (streaming) |
| PC addiction | High (screen active) | Medium (tab active) | Low (file transferred) |
| Picture quality | Depends on the signal | Adaptive (up to 4K) | Original file |
In the browser's casting menu, you can choose what you want to cast: a tab, the entire screen, or a specific file. Selecting "Cast screen" will display the entire desktop, similar to Miracast, but using a different compression codec. This can be useful if the first method is unstable.
Why might Chromecast not find my TV?
Often, the problem lies with antivirus software or Windows Firewall, which block local device discovery. Try temporarily disabling protection or adding an exception for the "Private" network.
The advantage of this method is the ability to control playback from a smartphone or tablet, provided they are connected to the same Google account. However, full functionality requires browser authorization. Image quality is often higher than with a direct Wi-Fi Direct connection, as it uses more efficient encoding.
Streaming from macOS and Apple devices (AirPlay)
Computer owners MacBook or iMac face compatibility issues as Apple uses its own protocol AirPlay, which is not supported natively on Android TV. However, the ecosystem Xiaomi solves this problem by installing third-party receiver applications that emulate AirPlay signal reception.
The most popular and often pre-installed solution is the app AirScreen or AirPinYou need to find them in the Google Play Store on your TV, install them, and launch them. Once launched, the app will create a virtual device that your Mac will see as native. Apple TV.
On your Mac, click the Control Center icon in the menu bar and select "Screen Mirroring." Your TV and set-top box should appear in the list (e.g., Xiaomi-AirScreen). Click to connect. Your macOS desktop will be streamed to your TV in real time.
It's worth noting that when streaming through emulators, there may be a slight lag in the mouse cursor, making this method less suitable for fast-paced games, but perfectly acceptable for viewing photos, videos, and presentations. Image resolution is usually automatically adjusted to the TV's display.
