Modern technology makes it possible to transform ordinary movie watching into a full-fledged cinema experience, and there's no need to look for long HDMI or USB cables to achieve this. Wireless connection has become a standard of living, freeing users from the tangled mess of wires and the limitations of cable length. Connecting a laptop to a TV Xiaomi Wi-Fi gives you access to massive media content on a big screen with minimal effort.
However, the process of synchronizing devices does not always go smoothly the first time, as there are several data transfer protocols, such as Miracast, DLNA And Google CastEach has its own setup and intended purpose, which affects image quality and connection stability. Understanding these differences will help you choose the optimal method for your needs, whether it's a presentation, a game, or watching a video.
In this article, we will examine in detail all available connection methods, focusing on operating systems. Windows 10 And Windows 11, which are most commonly used with smart TVs. You'll learn how to activate hidden features, eliminate lag, and configure audio without using third-party utilities.
Before you begin setup, make sure your equipment supports the required wireless standards. Most modern models Xiaomi Mi TV And Xiaomi TV Stick already have built-in modules for broadcasting, but the software may require updating.
Preparatory stage and network testing
The foundation for a successful connection is the proper organization of a local network in which both devices will operate. The laptop and TV Xiaomi must be connected to the same Wi-Fi network, otherwise they simply won't "see" each other in the list of available devices. If you have a dual-band router operating on 2.4 GHz and 5 GHz frequencies, it's advisable to have both devices connected to the same band. 5 GHz to ensure high throughput.
The speed of the wireless channel directly affects the quality of the transmitted image, especially if you plan to watch content in high definition. 4K or HDRIf the signal is too low, artifacts, audio desync, or playback may stop completely may occur. Check the signal strength on both devices and, if necessary, move the router closer to the viewing area.
- 📶 Make sure that AP Isolation is not enabled on your router, which prevents devices on the network from communicating with each other.
- 🔌 Check that the Wi-Fi module is enabled on the TV and that it is not in power saving mode, which disables the network adapter.
- 💻 Update your laptop's wireless adapter drivers to the latest version available on the manufacturer's website.
⚠️ Attention: If your router broadcasts two networks with the same name (SSID) for different frequencies, your laptop and TV may automatically switch between them, breaking the connection. For stable operation, it's best to explicitly separate the network names or force both devices to connect to the same frequency.
It's also worth considering that some corporate or public Wi-Fi networks have restrictions on the transfer of media traffic between devices. In a home environment, such issues are rare, but if you're using a complex network interface with VLANs, ensure that the devices are on the same network segment.
Using the built-in Projection feature in Windows
The fastest and most native way to display images from your laptop on your screen Xiaomi TV - this is the use of technology Miracast, which is built into the Windows operating system. This method allows you to completely duplicate or extend your desktop, making it ideal for sharing presentations, photos, or browser tabs. No additional software installation is required; Wi-Fi Direct support on both devices is sufficient.
To start broadcasting, press the key combination Win + K on the laptop keyboard. A "Connection" sidebar will appear on the right, where the system will begin searching for available wireless displays. If the TV Xiaomi turned on and is online, its name should appear in the list within a few seconds.
After selecting a device, a connection confirmation message may appear on the TV screen. Use the remote control. Xiaomito click "Allow" or "OK." From now on, the image from your laptop will be broadcast to the big screen. You can change the operating mode by clicking again. Win + P and selecting "Repeat" (screen copy) or "Extend" (second monitor).
☑️ Check before connecting Miracast
It's important to note that image quality when using Miracast depends on the wireless channel load. If you notice your mouse cursor twitching, try lowering your laptop's screen resolution or moving closer to the router. You can also disable hardware acceleration in your browser's graphics settings if you're experiencing video playback issues.
Stream media via DLNA and built-in player
If your goal is not to duplicate your desktop, but to watch movies, photos or listen to music stored on your laptop's hard drive, then the technology DLNA will work best. It allows the TV Xiaomi View shared folders on your computer as external media resources and play them natively using the built-in decoder. This reduces the load on your laptop and often ensures more stable playback of large files.
To use this method in Windows, you need to enable the "Media Streaming" feature. Go to "Control Panel" → "Network and Sharing Center" → "Media Streaming Settings." In the window that opens, click "Turn on media streaming" and find your TV in the list. Xiaomi, setting its status to "Allowed".
After setting up access, open the video folder on your laptop, right-click the file, and select "Cast to Device." Select your TV from the list. The video will begin playing on the TV screen, and your laptop will act as a remote control, allowing you to adjust the volume or skip forward and backward.
| Parameter | Miracast (Projection) | DLNA (Streaming) | Google Cast |
|---|---|---|---|
| Purpose | Screen mirroring, games, work | View videos, photos, music | Broadcasting from browser/apps |
| Latency | High (not for dynamic games) | Minimum | Average |
| Laptop load | High (encodes video) | Low (streaming only) | Low |
| File formats | Any (as on the PC screen) | Depends on the TV decoder | Depends on the application |
⚠️ Attention: Xiaomi Android TVs may not support all audio codecs (such as DTS or AC3) when playing via DLNA. If the video plays but there's no sound, use a third-party player on the TV or stream via Miracast.
The advantage of DLNA is that you can control playback with your TV remote, pause, and rewind without having to reach for your laptop. This makes it ideal for family movie watching.
What should I do if my laptop doesn't see my TV in DLNA?
Make sure the network profile is set to "Private" and not "Public" in your laptop's network settings. Windows blocks device discovery on public networks. Also, check the Network Discovery service in Control Panel.
Broadcasting via Google Chrome (Chromecast built-in)
Because televisions Xiaomi run on an operating system Android TV, they have built-in support for the technology Google CastThis allows you to broadcast the contents of a browser tab. Google Chrome or an entire desktop directly to your TV without complex network settings. This method is especially convenient for displaying websites, online videos from platforms without a native TV app, or YouTube.
To get started, open the Chrome browser on your laptop and click the three dots in the upper-right corner of the menu. Select "Save & Share" → "Cast." A list of available devices will appear in the window that appears. Click the name of your device. Xiaomi TV.
By default, only the current tab is broadcast. If you want to show everything that's on your screen, click the "Sources" drop-down menu and select "Broadcast Desktop." This action will require permission to capture the screen, which you'll need to confirm in the Windows system dialog box.
- 🌐 To stream video from DRM-protected sites, use a Chrome tab rather than the entire screen to avoid a black image.
- 🔊 In the source menu, you can select "Stream file" to open a video file from the disk directly through the browser and send it to the TV.
- ⚙️ You can adjust the quality of your Chromecast stream in your browser settings, choosing between high definition and high performance.
Connection stability via Chrome Cast directly depends on the laptop's processor performance, as the browser handles encoding the video stream in real time. On low-end laptops, this can cause system lag.
Setting up a Xiaomi TV to receive a signal
Although modern televisions Xiaomi Ready to connect out of the box, but sometimes manual activation of certain modules is required. Depending on the firmware version PatchWall or pure Android TV, the menu names may differ, but the logic remains the same.
To use Miracast (called "Wireless Display" on some firmware versions), you need to launch the corresponding app on your TV. Find the "Miracast" or "Cast" icon in the list of apps and open it. The screen will enter connection standby mode, and the TV's name will become visible to your laptop.
If you use Google Cast or DLNA features, you don't need to launch separate apps—these services are built into the system. Android TV and run in the background. However, make sure that in the system settings (Settings → Device Preferences → About) the latest updates are installed, as they often contain fixes to communication protocols.
In some cases, your laptop's antivirus software or built-in firewall may block incoming connections from the TV. If your devices see the network but can't connect, try temporarily disabling network protection in your antivirus software to test.
Resolving and eliminating delays
Even with proper setup, users may encounter technical issues. One of the most common is audio and video desynchronization or significant lag when moving the mouse. This is typical of wireless technologies and is often resolved by switching to a less congested Wi-Fi channel on the router.
If your laptop absolutely can't find your TV, try rebooting your router, as DNS cache or errors in the ARP table may be preventing detection. Restarting the UPnP Helper Service and SSDP Listener services in Windows (via services.msc).
Another common issue is low resolution of the streamed image. Make sure that in Windows display settings (System → Display → Advanced display settings) the TV's native resolution is set, usually 1920x1080 or 3840x2160Sometimes the system selects a low resolution by default to save traffic.
⚠️ Attention: The Xiaomi TV interface may be updated by the manufacturer, changing the settings layout. If you can't find the options described above, refer to the official documentation for your model or update the TV's software via the "About TV" menu.
Gamers planning to play over Wi-Fi should immediately abandon this idea in favor of wired HDMI. Even the best routers can't provide latency below 30-50 ms, which is critical for shooters and racing games. A wireless connection is ideal for video and static content, but not for fast-paced gaming.
Alternative methods and third-party applications
If standard Windows tools and functions Xiaomi TV don't provide the desired result, third-party solutions come to the rescue. Applications like LetsView, AirPlay (for macOS users) or TeamViewer can be a great alternative. They often have more flexible codec settings and cope better with unstable internet connections.
For equipment owners Apple (MacBook) support question is urgent AirPlayMany new Xiaomi TV models have built-in AirPlay 2 support, allowing you to connect via the standard "Screen Mirroring" menu on macOS without installing additional software. If built-in support isn't available, you can install the AirScreen app from the Google Play Store on your TV.
There are also specialized server programs such as Plex or Kodi, which can be installed on both a laptop (as a server) and a TV (as a client). This creates a powerful media system with a beautiful interface, movie posters, and automatic content sorting, surpassing the capabilities of the standard Windows Explorer.
Why doesn't my Xiaomi TV see my laptop in the list of devices?
Most often, the problem stems from different subnets. Make sure both devices are connected to the same network, not a guest network. Also, check if your PC's antivirus software is blocking local network discovery. In rare cases, resetting the TV's network settings may help.
Is it possible to play games from a laptop on a TV via Wi-Fi?
Technically, it's possible, but the experience will be poor due to input lag. While this is acceptable for strategy or card games, a 100-200ms lag will make gaming uncomfortable for action games and shooters. Using an HDMI cable is recommended.
How to improve picture quality during wireless broadcasting?
Use a router that supports Wi-Fi 5 (AC) or Wi-Fi 6 (AX). Connect your laptop and TV to the 5 GHz band. Close unnecessary bandwidth-consuming programs on your laptop and disable downloads on other devices on the network.
Do you need internet to connect a laptop to a TV?
Internet access is not required for Miracast and DLNA; a local Wi-Fi network is sufficient. However, for Google Cast and streaming services (YouTube, Netflix) to work, both devices need internet access.
