Modern Smart TV allow you to transform your living room into a real cinema, using content stored on your personal computer. Owners of the equipment Xiaomi People often wonder how to quickly and easily display high-quality images on a large screen without unnecessary wires. Fortunately, the built-in protocol Miracast and support of the standard DLNA make this process as simple as possible, without requiring the purchase of expensive cables.
There are several ways to implement wireless data transfer, each with its own advantages depending on your goals. You can mirror your desktop, stream video from your browser, or open files from your hard drive using the built-in media player. The method you choose depends on your PC's operating system and the type of content you're playing.
In this article, we will examine in detail all the current connection methods, paying special attention to the nuances of network setup. Wi-FiYou'll learn how to avoid lag, improve picture quality, and solve common problems that arise when pairing devices from different manufacturers.
Network requirements and equipment preparation
The first and most important condition for stable operation is that all devices are on the same local network. Your computer and TV Xiaomi must be connected to the same router, either via cable or over the air. If you're using a dual-band router, make sure both devices are operating on the same frequency, for example 2.4 GHz or 5 GHz.
For high definition video transmission 4K or Full HD To avoid compression artifacts, it's recommended to use the 5 GHz frequency band. It provides higher throughput, which is critical for streaming heavy video. At the same time, the 2.4 GHz band can handle the transmission of standard HD video, but it is more susceptible to interference from neighboring networks.
- 📺 Make sure that on your TV Xiaomi The wireless display function is enabled in the system settings.
- 💻 Check that the Wi-Fi adapter is activated on your computer and the drivers are installed correctly.
- 🔒 Make sure you select the "Private network" profile in your network settings, not "Public" to allow devices to be discovered.
⚠️ Note: If your router is configured to automatically switch clients between frequencies (Smart Connect), brief connection interruptions may occur. For a stable broadcast, it's best to force devices to use the same frequency.
It's also worth checking that the software on both devices is up-to-date. The manufacturer regularly releases updates that improve protocol stability. DLNA And MiracastOutdated firmware may contain errors that prevent proper handshake between the PC and TV.
Using the built-in Connect feature in Windows
operating system Windows 10 And Windows 11 have native support for Miracast technology, which allows you to stream images without installing additional software. On the TV Xiaomi You need to launch the "Wireless Display" app or a similar one, which is usually located in the app list or on the launcher's home screen Android TV.
After launching the application on TV, you should press a key combination on your computer Win + KThe "Connection" sidebar will open, where the system will begin searching for available devices. Your TV should appear in the list. Xiaomi, after which you just need to click on it to start pairing.
This method is ideal for displaying presentations, photos, or web pages, as it creates an exact replica of your desktop. However, keep in mind that when playing fast-paced videos or games, you may experience a slight input lag, known as input lagThis isn't critical for watching movies, but it may be unacceptable for first-person shooters.
☑️ Check before connecting Miracast
If the connection is established, but the image is choppy or has low resolution, try changing the projection settings. Click Win + P and select the "Extend" or "Second Screen Only" mode, which can reduce the load on the video adapter and improve image smoothness.
Broadcasting via Google Chrome browser (Chromecast)
Televisions Xiaomi run on an operating system Android TV, which has built-in support for the technology Google CastThis allows you to broadcast the contents of a browser tab. Google Chrome or the entire screen directly to your TV. This method is especially convenient if you want to display content from a website that doesn't have a dedicated app.
To get started, open your browser. Chrome on your computer and click the three dots in the upper right corner. Select "Cast" from the drop-down menu. The system will prompt you to select a source: you can cast a specific tab, the entire screen, or a file.
- 🌐 Open your browser menu and select "Stream".
- 🖥️ Select source: "Tab", "Full Screen" or "File".
- 📺 Click on your TV's name Xiaomi in the list of devices.
The advantage of this method is that you can use your computer for other tasks while the video plays on the big screen if you select Tab Casting. Furthermore, the image quality is often higher than with Miracast, as it uses a more efficient stream compression codec.
⚠️ Please note: When streaming your entire system through Chrome, the load on your computer's processor increases significantly. This may cause your laptop to overheat and reduce performance in other applications.
It is important to note that the quality of the stream directly depends on the speed of your Wi-Fi Connection. If the router is far away or the signal is weak, the browser may automatically reduce the video resolution to prevent buffering. In such cases, it is recommended to move the computer closer to the access point or use a wired connection for the PC, leaving the TV on Wi-Fi.
Why can't the browser see the TV?
If Chrome doesn't detect the Cast device, check if the local network is enabled in your antivirus or Windows Firewall settings. System traffic blockers often perceive the Chromecast discovery protocol as a potential threat and block broadcast requests. Add an exception for the local network in your security settings.
Organizing a media library via a DLNA server
If your goal is to watch movies stored on your computer's hard drive, the most effective solution is to create DLNA servers. TVs Xiaomi They work great with this protocol, allowing you to open files directly through the built-in player or the Media app without first buffering the entire file.
In the operating system Windows The media server feature is built-in by default. Simply open "Streaming Media Settings" in the Control Panel and enable this option. Afterward, your video, music, and image folders will be accessible to other devices on the network.
On your TV, launch the Media app or any file manager with DLNA support, for example, VLC for AndroidSelect your computer from the source list and navigate to the desired file. This method provides the best image quality, as the video stream is transmitted in its original bitrate without real-time re-encoding.
| Parameter | Miracast | Chromecast | DLNA |
|---|---|---|---|
| Transmission type | Screen mirroring | Streaming tab | File access |
| Delay | High | Average | Minimum |
| Quality | Depends on the signal | Adaptive | Original |
| PC load | High | Average | Low |
For advanced users, it is recommended to use specialized software, such as Plex or JellyfinThese programs don't just provide access to files; they also create a beautiful interface with posters, descriptions, and the ability to continue viewing from where you left off.
Third-party applications and utilities
Built-in operating system tools don't always provide the desired functionality or stability. In such cases, third-party solutions designed specifically for PC-to-PC interaction come to the rescue. Smart TVOne of the most popular and reliable tools is the program LetsView or AirPin.
These applications require client installation on both the computer (Windows/macOS) and the TV. Xiaomi (via the Google Play Store on TV). They often offer more flexible settings, such as phone control, on-screen drawing, or the ability to stream audio separately from the image.
Another powerful tool is KodiBy installing this media-central platform on your TV, you gain access to a huge number of plugins, including those that allow you to stream content from your PC using protocols SMB or UPnPThis turns an ordinary TV into a powerful multimedia combine.
- 📲 LetsView — a free cross-platform solution with good image quality.
- 🎬 Kodi — a powerful media center for advanced users with plugin support.

When choosing third-party software, pay attention to the presence of ads in the free versions and codec support. Some applications may not display subtitles correctly or support surround sound. Dolby Atmos, which is important for home theater.
⚠️ Please note: App and operating system interfaces may be updated by developers. The location of menu items or function names may differ from those described in the instructions. Always consult the manufacturer's current documentation if you cannot find the option you need.
Troubleshooting and optimization
Despite the ease of setup, users may encounter issues such as audio and video desync, low resolution, or constant connection drops. The first step in troubleshooting should always be checking the signal integrity. Wi-Fi.
If the image is streaming but buffering frequently, try lowering the output resolution on your computer. Sometimes the video card can't keep up with encoding a high-resolution stream for wireless transmission. Closing background applications that consume bandwidth, such as torrents or cloud syncing services, also helps.
In case the TV Xiaomi If your computer isn't detected at all, check your Windows Firewall settings. The system often asks about the network type when you first connect, and if you select "Public," many detection services are blocked. Change the network profile to "Private" in the Wi-Fi settings.
For router owners Mi Router or other models with the function IPTV It's worth checking whether the port is reserved for the set-top box, which can sometimes conflict with DLNA multicast traffic. Restarting the router and all devices in the chain also often resolves temporary software glitches.
Why is there no sound on the TV during broadcasting?
Most often, the problem lies in the Windows playback device settings. Click the speaker icon in the system tray, select the arrow next to the volume slider, and select your TV from the list of output devices. Xiaomi or "NVIDIA High Definition Audio" (if connected via an HDMI adapter, although with Wi-Fi, this is usually the name of a virtual device). If there's still no sound, check to see if the sound is muted in the app you're streaming from.
Is it possible to stream games from a computer to a Xiaomi TV without lag?
Playing fast-paced shooters or fighting games over Wi-Fi (Miracast) is nearly impossible due to input lag, which can reach 100-200 ms. For a comfortable gaming experience, we recommend using a wired HDMI connection or streaming services like Steam Link, which are better optimized for gaming, although they still require a perfect 5GHz Wi-Fi signal.
The TV sees the PC, but the folders are empty (DLNA).
This is a classic permissions issue. Go to "Streaming Media Settings," click "Configure," and make sure your TV is marked as "Allowed." Also, check that the video folder properties on the "Sharing" tab are set to "Everyone" or "MediaDevices."
