Modern multimedia capabilities allow you to easily stream content from your computer to a large screen, eliminating unnecessary wires. XiaomiAs a leader in the smart TV market, Samsung offers several built-in tools for wireless connectivity. Users often want to know how to display an image on the screen to watch a movie or share a presentation with colleagues.
The main principle of operation is based on technology Miracast or proprietary solutions Android TVFor a successful setup, the laptop and TV must be on the same local Wi-Fi network. This is critical, as separating the guest network from the main network can block device detection.
In this article, we'll take a detailed look at all available synchronization methods. You'll learn about standard tools. Windows And macOS, as well as specialized apps from the manufacturer. We'll cover the nuances of setting resolution and signal latency.
Preparing equipment and network for synchronization
Before you begin setup, make sure your router supports the standard. 5 GHzThis frequency solution provides higher throughput, which is critical for transmitting high-resolution video streams without compression artifacts.
Check for software updates on both devices. On the TV Xiaomi Go to the Settings menu and find the "About System" section. If a new firmware version is available, you must install it for the wireless modules to function correctly.
- 📶 Make sure your laptop and TV are connected to the same Wi-Fi access point.
- 🔄 Check if you have the latest Wi-Fi adapter drivers on your computer.
- 📺 Make sure that the "Wireless Display" or similar feature is enabled on your TV.
⚠️ Note: If you are using a dual-band router, make sure both devices are connected to the same frequency network (either both on 2.4 GHz or both on 5 GHz), otherwise they may not “see” each other due to client isolation.
Using the built-in Windows feature (Miracast)
operating system Windows 10 And Windows 11 have native support for the technology MiracastThis allows you to project an image without installing additional software. To launch, open the notification center and select "Project."
The system will start searching for available devices. Your device should appear in the list. Xiaomi Mi TVIf the TV is not displayed, it may not have the appropriate service running. On some models Android TV You must first launch the Wireless Display or Broadcast app.
After selecting the TV, a connection permission prompt will appear on the computer screen. Confirm with the remote. Your laptop screen is now mirrored on the TV.
⚠️ Note: The menu interface may differ depending on the shell version PatchWall or clean Android TVIf a standard search doesn't yield results, check the name of the streaming app in the official documentation for your model.
Setting up broadcast mode on a Xiaomi TV
Sometimes automatic detection fails and manual activation of the signal receiver is required. On the remotes Xiaomi There is often a separate button for calling up a menu of signal sources or quick applications.
Find the "Wireless Display" or "Miracast" icon in the app list. Once you launch this app, the TV will enter connection standby mode. The device name and connection instructions will appear on the screen.
In this same menu, you can adjust the display settings. For example, change the resolution or aspect ratio if the image is stretched incorrectly. The following can also be displayed here: IP address device that will be needed for advanced connection methods.
Broadcast via Google Chrome (Chromecast built-in)
Most TVs Xiaomi have built-in support for the technology ChromecastThis allows you to broadcast a browser tab. Google Chrome or the entire desktop directly through the browser.
Open the browser on your laptop, click the three dots in the upper right corner, and select "Cast." In the menu that opens, select the source: "Cast Tab" or "Cast Desktop."
Browser menu → Save and share → BroadcastThis method is especially convenient when you need to display the content of a specific web page or video from a site that doesn't support direct output. Image quality in this mode is often higher than with Miracast, as it utilizes the browser's hardware encoding.
- 🌐 Open the Chrome browser settings menu.
- 📡 Select the “Cast” option.
- 💻 Specify the broadcast source (tab or full screen).
Connecting MacBook and macOS devices
For laptop owners Apple a third-party solution will be required, since the protocol AirPlay Not all TV models support it natively. XiaomiHowever, many new models already have built-in AirPlay 2 support.
Check the macOS Control Center for the AirPlay icon. If your TV isn't detected, try installing an AirPlay receiver emulator app from the Google Play Store, such as "AirScreen," on your TV.
After installing the app on your TV, launch it. Your laptop will see the virtual receiver. The connection is instant, and you can mirror your screen or use your TV as a second monitor.
What should I do if I experience cursor lag?
If your mouse cursor lags behind your actions, try lowering the output resolution in Windows settings. The lag could also be caused by Wi-Fi congestion from neighboring routers. In this case, switching to channel 1, 6, or 11 in your router settings may help.
Using third-party apps and DLNA
If standard methods don't work, you can use proven third-party programs. One of the most popular is LetsView or AirDroid CastThey can be installed on both a PC and a TV (via an APK file or an app store).
There is also a technology DLNA, which is primarily designed for transferring media files, not screen mirroring. To do this in Windows, right-click the video file and select "Cast to device."
| Method | Delay | Quality | Complexity |
|---|---|---|---|
| Miracast | Average | High | Low |
| Chromecast | Low | High | Low |
| DLNA | Absent | Original | Average |
| Third-party software | Depends on the software | Average | High |
☑️ Check before connection
Troubleshooting connection issues
A common problem is when devices are on the same network but can't see each other. This may be due to Windows Firewall settings. Ensure the network is marked as "Private" and not "Public."
On the "Public" network, the system blocks device detection for security reasons. You can switch the network profile in the Wi-Fi connection settings. Also, try rebooting your router, as multicast traffic is sometimes blocked after a long period of operation.
Another reason is an outdated Wi-Fi security protocol. If your router is configured to only work in wireless mode, WPA3If your laptop is old, conflicts may arise. Try setting WPA2/WPA3 mixed mode.
Why can't my Xiaomi TV detect my laptop?
Most likely, the devices are connected to different frequency ranges (2.4 GHz and 5 GHz) with client isolation enabled on the router, or the network discovery service is disabled on the computer.
Is it possible to mirror the screen via Bluetooth?
No, Bluetooth bandwidth is insufficient for real-time video transmission. Use Wi-Fi or an HDMI cable only.
How to remove black bars at the edges of the screen?
Go to the picture settings on your TV (menu button on the remote) and change the screen format to “Fit to screen” or “16:9”.
