Modern users are rarely satisfied with small laptop screens when it comes to watching movies, TV series, or demonstrating presentations. Wireless connection has become a standard of convenience, allowing you to stream high-detail content to a large screen without the hassle of cables. Xiaomi And Redmi are in an advantageous position because the operating system Android TV or PatchWall provides wide possibilities for integration with external devices.
However, despite its stated simplicity, the synchronization process may encounter technical nuances depending on the version of the computer's operating system and the TV model. It is critical that both devices are on the same local Wi-Fi network, otherwise the devices cannot be detected. In this guide, we'll cover all the current image transfer methods in detail, eliminating complex technical jargon where possible and focusing on practical steps.
You don't need to be an engineer to set up a broadcast, but understanding the basic principles of operation data transfer protocols This will help you avoid errors. We'll cover built-in Windows and macOS features, as well as specialized apps that may be required for smooth operation. Let's figure out how to turn your TV into a fully-fledged monitor.
Preparatory stage: checking the network and settings
Before you begin synchronizing devices, you need to ensure the connection foundation is properly established. Often, users attempt to connect a laptop without meeting the basic requirements, which leads to detection errors. The first step is to ensure your router is transmitting a signal at the correct frequency. 2.4 GHz or 5 GHz, and both devices are connected to this network.
Simply connecting to Wi-Fi isn't enough; it's important for devices to "see" each other. Some routers have a client isolation feature (AP Isolation), which prevents devices from communicating with each other within the network. If you're using a guest Wi-Fi network, you may be unable to connect due to security restrictions.
- 📡 Make sure your laptop and TV are Xiaomi connected to the same Wi-Fi network (SSID name must match).
- 🔌 Check that the Wi-Fi module is enabled on the TV and the signal is stable (preferably above 70%).
- 🛡️ Disable the "Guest Network" feature on your router if it is active, as it blocks local data exchange.
- 🔄 Restart your router if the connection is unstable or devices cannot find each other.
It's also worth paying attention to the software. Make sure that the TV Xiaomi TV The latest firmware version is installed. Manufacturers regularly release updates that improve protocol compatibility. Miracast And Chromecast.
⚠️ Note: If your router is dual-band (distributes 2.4 and 5 GHz under different names), connect your laptop and TV to the 5 GHz network to stream 4K video, or make sure both devices are on the same subnet if the network names are different.
Using the built-in Connect feature in Windows 10 and 11
Operating systems of the Windows family, starting with version 10, have built-in support for the technology Miracast, which allows you to connect to compatible TVs without installing additional software. Xiaomi Mi TV And Redmi TV support this protocol out of the box, making the process as simple as possible for the user.
To start broadcasting, you don't need to search through complicated settings in the control panel. Simply use hotkeys or the notification menu. The system will automatically scan the broadcast for available displays. If your TV doesn't appear immediately, it may mean that the signal reception function isn't activated on the TV itself.
On some TV models Xiaomi You must first launch the application to receive the signal. It may be called Wireless Display, Cast or BroadcastWithout the app open, the TV may be in standby mode and not respond to search requests from the laptop.
☑️ Windows connection algorithm
Once the connection is successful, you can select a mode. Windows will offer several options: screen mirroring, desktop extension, or displaying only on the second screen. The choice depends on your needs: mirroring is more convenient for movies, while desktop extension is more convenient for work.
- 🖥️ Duplicate: the image from the laptop is completely copied to the TV (the same picture).
- 📐 Extend: The TV becomes a second monitor onto which you can drag windows (useful for multitasking).
- 📺 Second screen only: the laptop screen goes blank, the image is displayed only on the Xiaomi TV (saves resources).
- 💻 Computer screen only: Temporarily turn off your TV without interrupting the connection.
It is important to note that when using Miracast, there may be a slight image lag, known as latencyThis isn't critical for watching videos, but it can be noticeable for fast-paced games. Image quality may also automatically decrease if the Wi-Fi signal is poor.
Broadcasting via Google Chrome (Chromecast built-in)
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 broadcast the contents of a browser tab or the entire desktop, especially if the built-in Windows feature isn't working correctly.
To implement this method you will need a browser Google Chrome on a laptop. Most users have one, but if not, it's easy to install. The advantage of this method is that it's cross-platform and works equally well on Windows, macOS, and Linux.
Open your browser and click on the three dots in the upper right corner, then select Broadcast... (Cast). The system will begin searching for available devices. Your TV should appear in the list. XiaomiBefore you start broadcasting, you can click the "Sources" button to choose what you want to show: a tab, the entire screen, or a file.
⚠️ Note: Casting an entire tab can use significant CPU resources on your laptop. If the video is lagging, try closing any unused tabs or lowering the playback quality.
This method is especially useful if you want to display content from a website that doesn't have native Smart TV support, or if you need to demonstrate the functionality of a web service. The quality of data transmission through Chromecast usually higher than Miracast because more efficient compression is used.
Why does Chromecast sometimes work better than Miracast?
Chromecast uses Google's server-side encoding, which reduces the load on your local network and provides a smoother picture on weak Wi-Fi, while Miracast relies solely on the power of the devices' Wi-Fi modules.
Connecting MacBook and macOS devices
For laptop owners Apple You'll have to do things a little differently because the macOS ecosystem uses its own protocol. AirPlay. Televisions Xiaomi do not have built-in AirPlay support out of the box in the standard firmware, but this problem can be easily solved.
You'll need to install an app on your TV that emulates an AirPlay receiver. In the store Google Play Store There are many such applications available on the TV, for example, AirScreen or Receiver for AirPlayOnce you install and launch this app, your Mac will begin to see your TV as an Apple TV device.
The connection process is standard for Apple users: click the "Screen Mirroring" icon in the quick actions menu (Control Center) and select your TV. The image will be transmitted with minimal delay. It's important that the receiving app is running on the TV before attempting to connect.
Please note that free versions of emulator apps may have limited runtimes or display ads. For continuous use, it is recommended to purchase paid versions or explore alternative methods, such as VLC player.
- 🍏 Find in Google Play on the TV an application for AirPlay (for example, AirScreen).
- 📡 Launch the app on your TV and make sure the status is "Ready to connect."
- 🖥️ On Mac, click
Control Center→Screen mirroring. - 🔗 Select a TV from the list and enjoy the content.
Specialized applications and DLNA
If you need to broadcast not the entire screen, but specific files (video, photo, music), the optimal solution would be to use the technology DLNAIt allows you to transfer media files over the network without creating a full copy of the screen image, which reduces the load on the processor.
On TVs Xiaomi Often a media player that supports DLNA is pre-installed (for example, MX Player or built-in gallery). On a computer, simply open the file folder in File Explorer, right-click, and select Transfer to deviceHowever, for more advanced control, it is better to use specialized software.
A popular solution is the app VLC Media PlayerIt's available for all platforms and can function as both a server and a client. You can play video on your laptop and redirect the output to your TV via the menu. Playback → Renderer.
| Method | Latency | Quality | Best for |
|---|---|---|---|
| Miracast (Windows) | Average | High | Presentations, work |
| Chromecast | Low | Very high | Video, browser |
| AirPlay (via app) | Low | High | Mac users |
| DLNA / VLC | Absent | Original | Local files |
Using DLNA also allows you to control playback with your TV remote, pausing and rewinding videos, which is impossible with simple screen mirroring. This makes this method ideal for watching downloaded movies.
Troubleshooting and connection optimization
Even with proper setup, users may encounter issues such as audio and video desynchronization, low resolution, or constant connection drops. Most often, these issues are caused by Wi-Fi congestion or outdated drivers.
First, update the wireless adapter drivers on your laptop. Go to device Manager, find network adapters and update the software for your Wi-Fi module. On the TV Xiaomi Check for system updates in settings.
If the image is choppy or artifacts appear, try switching your router to a channel with less congestion. Neighboring networks may be interfering. Bandwidth adjustments may also help. 5 GHz, which is less noisy than 2.4 GHz, but has a shorter range.
⚠️ Note: Menu interfaces and item names may vary slightly depending on the PatchWall or Android TV firmware version. If you don't find an exact match, look for similar options.
In some cases, your antivirus or firewall software may be blocking incoming connections from your TV. Try temporarily disabling the protection or adding your home network to your trusted list.
