Xiaomi’s modern smart TVs have long since ceased to be just devices for receiving an air signal, becoming full-fledged multimedia centers. The ability to wirelessly connect to a personal computer gives users access to a huge array of content, allowing you to display movies, photos and even a desktop for presentations or games. Wireless connection eliminates the need to pull long cables across the room, preserving the aesthetic of the interior.
The synchronization process may seem complicated at first glance, but the Android ecosystem is a bit complicated. TV Or PatchWall, which is used in Xiaomi TVs, provides built-in tools for quick customization. You don't need special adapters or complex programs if both devices are on the same network. In this article, we will take a detailed look at all available methods, from the standard Miracast protocol to advanced use. DLNA-server.
It is worth noting that the stability of the connection directly depends on the quality of your router and the distance between devices. To transfer video in 4K resolution without delay, it is critical to use a dual-band router with support for 5 GHz. Let's look at how to prepare the equipment for work and what nuances should be considered by owners of different operating systems.
Preparation of equipment and network
Before you start setting up, make sure your local network is ready to transmit heavy media traffic. The most important requirement is that both your TV and your computer must be connected to the same Wi-Fi network. If you have a dual-band router, make sure that your gadgets are not spaced in different frequency bands (2.4 GHz and 5 GHz), as some discovery protocols may not see the devices on different subnets.
Check the software on your Xiaomi TV. Manufacturers regularly release updates to improve the stability of Wi-Fi modules and fix bugs in the data protocols. Go to the system settings and check for updates.
You should also pay attention to the power saving settings on your laptop, so if your computer goes to sleep while you're watching, the broadcast will be interrupted, and you can set up the power circuit so that the network card and the processor don't go into deep sleep without your knowledge.
💡
Place your router as close to viewing as possible, or use a Wi-Fi repeater if the signal in the room is weak, drastically reducing the amount of buffering when streaming high quality.
Broadcasting Windows screen through Miracast
Windows 10 and 11 have a built-in projection feature based on the Miracast standard. Xiaomi Android TVs have a built-in receiver that allows you to duplicate the screen without installing additional software. First, make sure that the wireless display feature is active on the TV.
On the remote, click the source menu button or find the "Wireless Display", "Miracast" or "Translation" app. In some Xiaomi firmware, this feature is built directly into the system and activates automatically when you search for a device from a PC. Once you start on the TV screen, you will expect a connection.
Now, to your computer. Press the Win + K keyboard. On the right, the Connect panel will open, where the system will start looking for available wireless displays. Your Xiaomi TV should appear on the list. Click on it, and in a few seconds, the monitor image will appear on the big screen.
If the connection is successful, you can choose to work: duplicate screens, expand the desktop or output only to the second screen, which is convenient for watching video in the browser while you are working with documents on the main monitor.
⚠️ Note: Miracast may cause a slight input lag, which is normal for wireless technology, but makes it unsuitable for dynamic shooters where every millisecond counts.
☑️ Checking before connecting Miracast
Using DLNA to play files
If your goal is not to duplicate the screen, but to simply play a movie or photos stored on your computer's hard drive, DLNA technology is the best option. It allows your TV to see shared PC folders as network storage. In Windows, this feature is called Media Stream.
To set up, go to Settings -> Network and Internet -> Status. Find the link "Multimedia Streaming Options." In the window that opens, click "Enable Media Streaming." The system will prompt you to name the library and select the devices that are allowed access.
Find your Xiaomi TV on the list and make sure it ticks "Allowed." Then open "Conductor," select a folder with a video or photo, right-click and select "Transfer to the device." Your TV should be on the list.
Alternative and more flexible way – installing a third party DLNA-servers, such as Universal Media Server or the use of an embedded server in a player VLC. This gives more transcoding settings if the TV doesn't support the video file format.
| Parameter | Miracast (Translation) | DLNA (Media Server) | Chrome Cast |
|---|---|---|---|
| Appointment | Duplication of PC screen | File reproduction | Broadcasting browser tabs |
| Delay. | Low/Mediocre | Absent. | Depends on the network. |
| Formats | Image mirror | Supported TV | Web content |
| Management | Computer from computer | From the TV remote | From computer/phone |
Why can't DLNA see all the files?
Broadcasting via Google Chrome
Google Chrome is a powerful tool not only for surfing, but also for managing content on Xiaomi TVs, because the Android TV operating system is based on the same principles, which is ideal if you want to show the contents of the tab or the entire desktop without using Windows system settings.
Open the Chrome browser on your computer. Click on the three dots in the top right corner of the menu and select "Cast." The browser will start searching for Chromecast built-in devices that are in every modern Xiaomi TV.
In the window that opens, you can choose the source: Tab, Whole Screen, or File. The Whole Screen option actually turns this method into a Miracast analog, but it often works more stable thanks to Google optimization. Click on your TV name to start the broadcast.
To stop the broadcast, click on the Cast icon in your browser again and select Stop. This method also allows you to quickly stream individual video files from your hard drive by selecting the Translate File option, which eliminates the need to configure complex files. DLNA-server.
⚠️ Attention: When broadcasting the whole screen through Chrome, the load on the computer processor can significantly increase, which will lead to heating of the laptop and fan noise.
Third-party synchronization applications
Staffing doesn't always provide the desired functionality or stability, and in these cases, specialized applications that are installed on both PCs and TVs come to the rescue. One of the most popular solutions is AirScreen (on TV) and standard Windows tools, or LetsView.
LetsView works on both platforms, and allows you not only to duplicate the screen, but also to control the computer from the remote, take screenshots and even use the phone as a touchpad.
Another option is to use the SMB protocol through file managers. Install a file manager on your TV that supports the network (such as X-plore or File Commander). In Windows settings, share a folder with SMB access. In the TV app, select Local Network or SMB, and you will have direct access to the computer's file system.
This method is good because it allows you to work with the file structure directly, copy files and run them with the native TV player, bypassing the limitations of DLNA on metadata and formats.
💡
Third-party applications often bypass protocol limitations by providing more flexible picture quality and sound settings.
Solutions and Connection Problems
Despite the ease of setting up, users often experience a situation where the computer can't see the TV or the connection is constantly broken. The most common reason is setting up the Windows firewall. When you first connect, the system asks about the type of network: select "Private Network" to allow device detection.
If the devices are on the same network but can't see each other, try temporarily disabling antivirus or firewall. DHCP-The server could issue addresses from different subnets or accumulate caching errors. ARP-table.
Image quality issues (artifacts, jerks) usually indicate Wi-Fi overload. Try switching your router to a less loaded channel or, if possible, using a cable connection for your PC, leaving Wi-Fi only for your TV.
