Modern Xiaomi TVs and Mi Box consoles are powerful multimedia centers, but their full potential is only realized when integrated with a computer. The ability to stream images from a laptop or desktop screen to a large display opens up access to quality content, presentations and games without the need for long cables. Users often look for ways to do this quickly without facing delays or loss of image quality.
In this guide, we will cover all current connectivity methods, from built-in Windows system functions to specialized applications, learn how to configure wireless data transmission over Wi-Fi and what network parameters are critical for stable operation, and also touch on wired options that can be a salvation in the absence of a wireless module or unstable signal.
The main goal is to make you comfortable using Android TV or MIUI for TV in conjunction with your personal computer. Whether you are running Windows 10/11 or using macOS, there are proven algorithms for actions. It is important to understand the differences between simple mirroring and streaming media files.
Preparation of equipment and network for synchronization
Before you start setting up, you need to make sure that both devices are in the same information space, a fundamental requirement for most data protocols to work, and your computer and Xiaomi TV must be connected to the same Wi-Fi hotspot on the router.
Note the frequency of wireless signal. For high-resolution video, especially in 4K, it is desirable to use the 5 GHz band. It provides higher bandwidth and is less susceptible to interference from neighboring networks or household appliances.
If your router supports guest networking, make sure devices are not spread across different subnets with client isolation.In some corporate or complex home networks, this can block the computer from detecting the TV.
⚠️ Note: If your router broadcasts two networks (2.4 GHz and 5 GHz) with different names (SSID), Connect both devices to one of them, even if they are in the same physical location.
It’s also worth checking the relevance of firmware on your TV.Outdated MIUI TV software may contain bugs that prevent Miracast from working properly. The update often solves problems with the device’s visibility in the list of available displays.
Wireless streaming via Miracast in Windows
The most native way for Windows 10 and Windows 11 users is to use the built-in Connection feature. Miracast technology allows you to transmit images and sound without installing additional software. Xiaomi TVs usually support this standard out of the box.
To start the process, on the TV remote, find the button to call the signal source menu or applications. You need to run an application that can be called Wireless Screen, Wireless Display or Miracast. On some Android TV models, it is enough to simply turn on the TV and wait for the model name to appear in the list of available Windows devices.
On your computer, press the Win + K key combination. On the right side of the screen, the Connect panel will appear. The system will start searching for available displays. When your Xiaomi TV appears on the list, click on it.
☑️ Checking before connecting Miracast
Once connected, you can select the mode of operation. Press Win + P to switch between "Duplicate", "Expand" or "Second screen only". Expand mode turns the TV into a second monitor, which is convenient for working with windows.
What if Windows can’t see the TV?
Using Google Chromecast technology and Chrome browser
Since most Xiaomi TVs run on Android TV or have a built-in Chromecast, using Google Chrome is one of the most stable methods.This is ideal if the built-in Windows feature is running with delays.
Open the Chrome browser on your computer. In the upper right corner, click on the three vertical menu points and select Translate... (Cast).
In the window that opens, it's important to choose the right source. The default is "Tab," but to broadcast the entire desktop, you need to select the option Broadcast screen, which will allow you to show not only the browser, but other open programs, folders and start menus.
| Parameter | Description | Recommendation |
|---|---|---|
| Permission | Depends on the PC monitor | Install 1920x1080 for better compatibility |
| Frequency of personnel | Hertsovka derivation | 60 Hz for video, 30 Hz for static |
| Codec | Compression format | VP9 or H.264 (automatically) |
| Delay. | Response time | 2-5 seconds (not for dynamic games) |
The quality of the broadcast depends on the power of your Wi-Fi router. If the image twitches, try lowering the resolution in the Windows settings before you start broadcasting, and it is also worth closing the heavy background processes on the computer to free up the CPU resources to encode the video stream.
💡
To reduce latency when streaming through Chrome, close all unnecessary tabs and applications that consume traffic, such as torrents or cloud syncs.
Third-party applications for advanced broadcasting
If standard methods don’t meet your quality or functionality requirements, you should turn to third-party software. Apps like LetsView, AirDroid Cast or ApowerMirror offer advanced management capabilities.
These programs often allow not only to duplicate the screen, but also to control the computer from the TV remote (if you have a mouse or a gyroscope), transfer files and even broadcast sound from the microphone of the PC, which turns the TV into a full-fledged interactive display.
To install such software, you will need to download the client part on your PC and the application from the Google Play store on your Xiaomi TV. QR-code PIN-code.
⚠️ Warning: Free versions of third-party apps often have session time limits or add watermarks to the image.
The DLNA protocol is particularly noteworthy: it doesn't broadcast the entire screen, but it allows you to open video files, photos and music from a computer on a TV. In Windows 10/11, this is done through the Flow function in the Photos app or through media servers like DLNAA Server.
Wireless connection via HDMI cable
Despite the popularity of wireless technology, cable connectivity remains the gold standard of quality. If you want a picture in 4K HDR without compression artifacts and with minimal input lag, HDMI is the choice.
Use an HDMI 2.0 or higher cable if you plan to transmit 4K images at 60 frames per second. Older 1.4 cables may not pull this flow, limiting the frequency to 30 Hz, which will make the mouse cursor movement unpleasant.
Connect the cable to a PC graphics card and free port on your TV. Switch the signal source to the TV with the Input button or through the source menu by selecting the appropriate connector (for example, HDMI 1 or HDMI 2 (ARC)).
Once connected, Windows will automatically detect a new display. If no image, check the resolution settings. Xiaomi TVs often require HDMI 2.0 in the settings of the TV itself (usually under "Entries" or "General") to activate the full port bandwidth.
💡
The HDMI cable delivers zero latency and maximum quality, which is critical for gaming and 4K high bitrate content.
Resolving image problems and delays
A common problem with wireless broadcasting is desynchronizing audio and video or “slowing down” the cursor, which is often associated with overloading the wireless channel. Try turning off other devices that are actively consuming traffic (smartphones, tablets).
If there is no sound, check the playback device in Windows. Click on the speaker icon in the tray and select your Xiaomi TV as the default output device. Sometimes the system continues to output sound through the laptop speakers.
If you have a permanent connection break, check the Wi-Fi adapter's power saving settings on your computer. Find your wireless module in Device Manager, go to properties, and uncheck the Power Management tab from the "Allow this device to be turned off to save energy."
⚠️ Warning: Antiviruses and firewalls can block the connection. If nothing helps, try temporarily disabling third-party antivirus or adding a broadcast app to exceptions.
It is also worth mentioning the problem with DRM-Some streaming services (Netflix, Disney)+) They can block the screen from streaming through Miracast or Chrome because of copy protection, and in these cases, a black screen with sound is a normal defense behavior. HDCP.
