Modern technology allows you to completely eliminate unnecessary cables in the living room, turning content viewing into a truly comfortable experience. Connecting a laptop to a TV Xiaomi or Mi TV Wirelessly access your vast media library, games, and work presentations on a large screen. This solution is ideal for those who appreciate aesthetics and minimalism in their interiors.
Unlike wired connections such as HDMI, wireless data transfer requires configuration of both devices and an understanding of how the protocols work. Miracast or DLNADespite the apparent complexity, the process only takes a few minutes. In this article, we'll cover all synchronization methods in detail, from built-in Windows functions to specialized software.
You'll learn how to ensure stable high-definition image transmission and what to do if devices can't see each other. We'll cover the nuances of working with various operating system versions and TV models. A willingness to experiment and a stable home network are all you'll need.
Network requirements and preparation steps
The foundation of successful wireless streaming is a high-quality local network. First, make sure your laptop and TV are Mi connected to the same Wi-Fi network. This is critical, as device discovery protocols often don't work over guest networks or when using different frequency bands.
It is recommended to use a range 5 GHz, if your router supports this technology. It provides higher throughput, which is necessary for transmitting 4K or HDR video streams without lag or compression artifacts. The 2.4 GHz frequency may not be stable enough for demanding tasks.
⚠️ Note: If your router uses the "Smart Connect" feature, which combines 2.4 and 5 GHz networks under one name, and devices are not found, try temporarily separating them into different SSIDs in the router settings.
Also check that your TV has the latest firmware version installed. MIUI TV or Android TVManufacturers regularly release updates that improve the stability of Wi-Fi modules and compatibility with external signal sources.
Using the built-in Projection feature in Windows
Windows 10 and 11 operating systems have a powerful built-in tool for wireless image transfer. Technology Miracast, implemented in these operating systems, allows you to broadcast your screen without installing additional software. TVs Xiaomi Android TV-based devices natively support this standard.
To start the process, press a key combination on your laptop keyboard Win + KThe "Connection" sidebar will appear on the right. Your TV should appear in the list of available devices. Mi TVIf it's not there, make sure the "Wireless Monitor" app or something similar is running on the TV itself.
After selecting a device, a connection confirmation prompt may appear on the TV screen. Use the remote control to accept the request. You can adjust the image quality in "Settings" -> "System" -> "Project to this PC."
☑️ Check before connection
It's important to note that when using this method, the laptop acts as the signal source and the TV as the receiver. Input lag may vary depending on the Wi-Fi module's power.
Broadcast via Google Chrome browser and Chromecast
Most TVs Mi have built-in support for the technology Google Cast (Chromecast built-in). This allows you to broadcast the contents of your browser tabs. Google Chrome directly onto the big screen. This method is especially convenient for viewing web pages, videos from sites that don't have their own apps, or presenting documents.
Open the Chrome browser on your laptop and click the three dots in the upper-right corner of the menu. Select "Cast." A list of available devices will appear in the window that opens. Click the name of your TV.
By default, only the current tab is cast. However, by clicking the "Sources" button, you can select "Cast Screen" to display the entire desktop. This turns your laptop into a full-fledged media station.
⚠️ Note: When casting an entire browser tab, audio may be delayed. For watching movies, it's best to use built-in players or Miracast.
Why is the picture quality in Chrome worse than via cable?
The browser compresses the video stream for fast network transmission, which can result in loss of detail in dark scenes and compression artifacts. A direct HDMI connection avoids this drawback, as it transmits an uncompressed signal.
The advantage of the Chromecast method is its ease of control: you can switch between windows on your laptop, and the image on your TV will not change if a specific tab is being cast.
Using Third-Party Applications: AirPlay and Utilities
If standard methods don't satisfy you in terms of functionality or stability, consider third-party solutions. For equipment owners Apple (MacBook) support is up to date AirPlay 2, which can be activated on TVs Mi by installing the AirPlay/DLNA Receiver application from the Google Play Store on the TV itself.
For Windows users, emulator programs such as LetsView or AirServerThey create a virtual receiver on a PC or improve transmission quality on a TV. Installing such software on a TV (via an APK file) can expand the functionality of the built-in receiver.
There are also specialized applications for transmitting multimedia using the protocol. DLNA, For example, BubbleUPnPInstead of mirroring your screen, they allow you to send specific video or photo files to your TV, freeing up your laptop's processor.
When choosing third-party software, pay attention to its resource consumption. Some "heavy" applications can cause the TV interface to lag, especially on models with limited RAM.
Comparison of connection methods and their characteristics
Choosing the optimal connection method depends on your goals: whether you're gaming, watching movies, or giving a presentation. Each method has its own technical characteristics that affect latency, image quality, and ease of use.
Below is a comparison table of the main wireless connection technologies available for laptop-TV connections. Mi.
| Technology | Latency | Image quality | Best use |
|---|---|---|---|
| Miracast (Win+K) | Average (50-100 ms) | High (up to 4K) | Work, presentations, photos |
| Google Cast | High (>200 ms) | Depends on the tab | Web surfing, YouTube |
| AirPlay 2 | Low/Medium | Excellent color rendering | macOS/iOS users |
| DLNA | No (streaming) | Original file | Viewing movies from folders |
As the table shows, low-latency technologies are better suited for dynamic content. However, for static movie viewing, the difference may be imperceptible to the human eye.
Troubleshooting connection and stability issues
Even with proper setup, problems may still occur: signal interruptions, audio desynchronization, or a complete lack of video in the device list. Often, the problem lies with Windows Firewall or antivirus settings blocking incoming connections.
Try temporarily disabling your firewall or adding the Projection app to the exceptions list. Restarting your network equipment can also help: unplug your router and TV for 30 seconds, then plug it back in. This clears the network error cache.
If the image is choppy or low resolution, check your Wi-Fi bandwidth. Downloading large files on other devices on the network can choke the video stream.
⚠️ Note: Menu interfaces and item names may differ depending on your TV's operating system version (Android TV, Google TV, PatchWall). Always consult the manufacturer's latest documentation for your model.
In some cases, updating your laptop's wireless adapter drivers can help. Visit your laptop manufacturer's website and download the latest drivers for your Wi-Fi card model.
Frequently Asked Questions (FAQ)
Is it possible to connect a laptop to a Mi TV if there is no router?
Yes, this is possible using Wi-Fi Direct technology. The TV will create its own hotspot, which you can connect to from your laptop. However, the data transfer speed may be lower, and your laptop's internet connection will not work at this time.
Why doesn't the TV see the laptop in the list of devices?
The most common cause is that the devices are on different subnets (for example, one on a guest network and the other on the main network). Also, check if your antivirus software is blocking network discovery.
Does wireless connection affect internet speed?
Yes, streaming high-definition video consumes a significant amount of bandwidth. If your bandwidth is limited, download speeds on other devices may decrease.
How to improve sound quality during wireless streaming?
In Windows sound settings, select the TV as the default output device. If the sound is choppy, try lowering the bitrate in the audio format settings or switching to a wired connection.
