Modern Smart TV Xiaomi TVs offer a wide range of features that are often underestimated by users who limit themselves to watching broadcast TV. However, one of the most powerful tools is the ability to wirelessly connect a computer to a TV via a local network. WiFiThis opens up access to vast media content on a large screen, allowing you to run PC games, present presentations, or simply watch movies from your hard drive without the hassle of wires.
The process of pairing devices may seem complicated at first glance, but it's actually based on standard data transfer protocols. In this article, we'll cover all the current methods, from built-in Windows functions to specialized software, so you can choose the best option for your situation. The main requirement is that both devices must be on the same network, which is a fundamental requirement for DLNA and Miracast technology to work.
Before you begin setting up, make sure your router supports the standard. 5 GHz, as this will significantly improve the stability of high-resolution video streaming. Using the 2.4 GHz frequency is possible, but may result in latency and reduced image quality when streaming heavy 4K content.
Preparing equipment and network settings
The first step is to properly prepare the infrastructure, without which a stable connection is impossible. You need to make sure that both the computer and the TV Xiaomi Mi TV connected to the same access point. If you have a dual-band router, it's best to use the same frequency for both devices to avoid possible routing conflicts within the local network.
Go to your TV's network settings and check the IP address assigned by the system. Make a note of it, as some connection methods, especially when using third-party players, will require you to manually enter these numbers on your computer to identify the device.
⚠️ Important: Make sure "AP Isolation" is disabled on your router. If this option is enabled, devices on the WiFi network will see the internet but will not be able to communicate with each other, making connection impossible.
It's also worth checking your computer's discovery settings. In Windows, network discovery must be enabled so that your PC can "see" your TV and vice versa. To do this, go to Control Panel → Network and Internet → Network and Sharing Center and select your network profile as "Private".
Mirror your screen using Miracast in Windows 10 and 11
The easiest and fastest way, which does not require installing additional software, is to use technology MiracastWindows 10 and 11 operating systems have built-in support for this standard, which allows you to mirror your desktop image or extend it onto your TV screen. Xiaomi Android TVs also support this protocol out of the box.
To start the process, find the application menu button on your TV remote control and launch the application. Wireless display or CastOn some models it may be called Wireless DisplayAfter launch, a waiting for connection message will appear on the screen.
Now let's move on to the computer settings. Press the key combination Win + K on the keyboard. The "Connection" panel will open on the right, where the system will search for available devices. Once your Xiaomi TV appears in the list, tap it to pair it.
☑️ Checklist for a successful Miracast connection
Once the connection is successful, you can select the operating mode. Click Win + Pto choose between screen duplication (copy) or extension (second monitor). This is especially convenient for working with graphics editors or watching videos in a browser window on a larger screen.
Using DLNA to Play Your Media Library
If your goal is not to broadcast your desktop, but simply to play a movie or music stored on your PC's hard drive, the protocol is best DLNAIt provides more stable playback of high-bitrate video files, as it does not burden the computer's processor with rendering the entire interface.
Windows 10 and 11 have a built-in media server feature, but it's limited. For full functionality, we recommend installing a free media center, such as Kodi or PlexHowever, you can also use standard tools. Open "Streaming Media Settings" in Windows Search and allow file access for your TV.
On your TV, launch your default video player or file manager. Select your computer from the list of sources. You'll see shared folders. Simply select a video file, and it will play on your TV using your remote.
| Protocol | Latency | Picture quality | PC load |
|---|---|---|---|
| Miracast | Low (noticeable in games) | High (on-the-fly compression) | Average |
| DLNA | None (buffering) | Original (no loss) | Low |
| Chromecast | Average | High | Depends on the browser |
The advantage of DLNA is that you can turn off your computer monitor or minimize all windows, and playback on your TV will not be interrupted. This is ideal for watching TV series in the evening, with your computer acting as a server.
Remote control and demonstration applications
In situations where standard protocols are unstable or advanced management features are required, specialized utilities come to the rescue. One of the most popular and reliable is AnyDesk or TeamViewer, although they are more focused on remote support, their screen sharing features work on a local network as well.
For more specialized tasks, such as controlling presentations or the cursor from a remote, you can use the app Mi Remote or third-party analogs like Mouse ToggleHowever, for image transmission, the Chromecast method has proven to be the best.
If your computer is running the Google Chrome browser, you can cast a tab directly to your TV. Click the three dots in the browser menu and select "Cast." The system will find Chromecast built-in devices, which are included in every Xiaomi TV.
⚠️ Important: When broadcasting a browser tab, make sure the quality settings are set to "High Quality (1080p)." By default, the browser may select automatic mode, which, if the WiFi signal is weak, will reduce the resolution to 480p, making the text unreadable.
This method is advantageous because it doesn't require complex network settings. It's enough for the browser and TV to "see" each other. The downside is that only the contents of the tab are broadcast, not the entire desktop (although there is an option to broadcast the entire screen).
Why does the video lag during broadcasting?
The main cause of lag and artifacts is WiFi congestion. If the router is simultaneously distributing internet to smartphones and downloading torrents, the bandwidth may not be sufficient for the video stream. Solution: Disconnect unnecessary devices or switch to 5 GHz.
Troubleshooting connection issues
Even with proper setup, problems can still occur. Users often encounter a situation where the computer simply doesn't see the TV in the list of available devices. First, check whether your antivirus or built-in software is blocking the connection. Windows Firewall.
Try temporarily disabling your firewall and checking for the device. If the TV appears, you'll need to add an exception rule for the Media Server service or the specific app you're using for streaming.
Another common issue is audio and video desynchronization. This can be resolved by increasing the playback buffer in the TV player settings or updating the network card drivers on the computer. Outdated WiFi adapter drivers often don't work correctly with modern WPA3 encryption protocols.
In some cases, a complete reset of network settings helps. On Xiaomi TVs, this can be done through the menu. Settings → Network → ResetOn a computer, you can use the command in the command line: netsh winsock reset, after which a reboot is required.
Comparison of wired and wireless connections
Despite the convenience of WiFi, the advantages of a wired connection via HDMI or LAN can't be ignored. Wireless connections are always susceptible to interference from microwave ovens, neighboring routers, and the thickness of walls. For mission-critical tasks like professional video editing or competitive gaming, cable remains king.
However, when it comes to comfortable content viewing, modern WiFi 5 (AC) and WiFi 6 (AX) standards provide sufficient bandwidth to transmit 4K HDR streams without loss. Xiaomi TVs are often equipped with dual-band modules, making them excellent receivers.
Choose WiFi when aesthetics, the absence of unnecessary wires, and portability are important. Choose cable when you need maximum stability and minimal input lag. For most home use cases, wireless offers the optimal balance.
FAQ: Frequently Asked Questions
Is it possible to connect a computer to a Xiaomi TV if there is no WiFi?
