Modern multimedia systems make it easy to stream content from laptops to large screens, turning the living room into a real theater. Connecting a laptop to a Xiaomi TV via WiFi wireless is one of the most convenient ways to eliminate unnecessary wires and distance restrictions, a method that is especially relevant for those who appreciate the cleanliness of the interior and the mobility of devices.
Unlike cable connections like HDMI, wireless data transfer requires both devices to be configured correctly and understanding the principles of media protocols. Users often face difficulties in discovering devices or choosing the right software. In this article, we will discuss all the nuances in detail so that you can enjoy content without delay and failure.
Before you start setting up, make sure that your Smart TV is running on Android TV or PatchWall, as this determines the functionality available. The laptop must also meet the minimum technical requirements for stable operation on the local network. Only if these conditions are met can you expect high-quality picture and sound.
The main advantage of this connection is that you can control presentations or videos directly from your computer keyboard, anywhere in the room, and you can simultaneously work on your laptop and show slides to colleagues, or run a movie and control playback without getting out of the couch, which opens up new horizons for using Xiaomi technology in the home and office.
Preparation of equipment and WiFi network
The first and most important step is to ensure a stable connection between devices: both the laptop and the Xiaomi TV must be connected to the same wireless WiFi network. If you have a dual-band router, it is advisable to use 5 GHz to transmit heavy video content in high resolution.
Check that the TV is enabled with wireless and the signal waiting mode is activated. The Smart TV network settings usually display the name of the device that will be visible to other gadgets on the local network. Make sure that the router does not activate customer isolation, which blocks the exchange of data between connected devices.
For a laptop, it is important to have a good network adapter and drivers installed. Sometimes the problem lies in outdated drivers that do not allow you to correctly detect media devices on the network. Updating network software can solve the problem of the disappearance of the TV from the list of available connections.
☑️ Checking before connection
It should be noted that the data transfer speed directly depends on the quality of the router signal. If there are many walls between the laptop and the access point or the distance is large, you may slow down when broadcasting video in 4K. In such cases, it is recommended to bring the laptop closer to the router or use a repeater to amplify the signal.
Use of the built-in Miracast feature in Windows
Windows 10 and Windows 11 have built-in support for Miracast, which allows you to broadcast a screen image without installing additional software. This native solution is the most stable for PC owners based on Microsoft products. To start the broadcast, you need to open the notification center and select "Project".
Once the search function is activated, the system will start scanning available displays within network range. On the Xiaomi TV screen, a request for connection permission may appear, which must be confirmed by the remote control. Some TV models require pre-launching the Wireless Display app or similar.
💡
If the TV is not automatically located, try in the Project app to click Connect to the Wireless Display at the bottom of the list and enter IP-hand-mail.
Projection modes allow you to flexibly adjust the screens, you can duplicate an image, expand your desktop to a TV, or use it as a second monitor, and the mode you choose depends on your tasks: duplication is good for viewing photos and videos, and extension is good for work.
It's important to consider that Miracast technology creates a direct connection that can be loading on a laptop's CPU. If you notice a performance decline in games or heavy programs, try lowering output resolution or closing background applications, which will help smooth out possible micro-image latency.
Broadcasting through the Google Chrome browser
If the built-in Windows tools don’t work or require more flexible settings, Google Chrome is a great solution. It has a built-in Chromecast feature, which is natively supported by Xiaomi TVs with Android TV. This allows you to broadcast not only the browser tabs, but also the entire screen or individual files.
To start the broadcast, click on three dots in the upper right corner of the browser and select Translate. From the menu that opens, you can select the source: tab, full screen or file. The TV should be visible in the list of available devices if it is connected to the same WiFi network.
| Parameter | Description | Recommendation |
|---|---|---|
| Source | Tab / Screen / File | For the video, it is better to choose "Tab" |
| Quality. | Depends on the network. | Use 5GHz for 4K |
| Delay. | Low/Mediocre | Not suitable for dynamic games |
| Audio. | Transmitted automatically | You can turn off the tab settings |
The thing about Chrome is that you can control playback from the browser, so you can pause, rewind, and adjust volume without using the remote, and that makes content management as user-friendly as possible.
Remember, when you stream a full screen, you get a lot of load on the system. If the picture starts to crumble or twitch, try closing tabs or reducing the resolution of the broadcast window. Browser technology is optimized for streaming video, but heavy graphics can be difficult.
Application of specialized software and DLNA
For users who need to transfer media files to the screen, DLNA technology is ideal: it allows you to open videos, photos and music stored on the laptop hard drive directly through the TV interface. To implement this method, you need to install a media server on your computer, such as DLNA Server or use a built-in Windows Media Center.
After you set up folder sharing, your computer will appear on Xiaomi TV in the Media section or through an application player (for example, VLC or MX Player), you can browse the laptop file system and run content of any gravity, since the TV itself is decoding.
⚠️ Attention: When in use DLNA Make sure that your Windows firewall settings allow you to access a private network. If your network profile is set to Public, your TV may not see your computer for security reasons.
There are also third-party client applications, such as AirScreen or ApowerMirror, which are installed on the TV and laptop respectively. They often provide advanced functionality, including audio from the microphone of the laptop or mouse control from the remote.
The use of specialized software is justified if standard methods do not support certain file formats or codecs. Software players based on Android TV often have their own built-in decoders, which solves compatibility problems, this is especially true for rare video formats.
Solving Connection Problems
Despite the simplicity of the technology, users can encounter a number of common errors, most often the problem lies in the difference in protocol versions or the blocking of ports by antivirus. If the laptop does not see the TV, the first thing you should do is try to restart the router - this updates DHCP-leases and resets network conflicts.
Another common reason is the use of a guest WiFi network. Many routers by default isolate guests from the local network, making it impossible for a computer to detect the TV, switch both devices to the main network, or turn off customer isolation in the router settings.
What if there is a picture but no sound?
Image delays (lags) can be caused by neighbor routers overloading the WiFi channel, and changing the channel in the router's settings to a less loaded router will help. Use the WiFi analysis apps on your smartphone to find the free frequency.
If the image appears but fades quickly, check the power saving settings of the WiFi adapter on your laptop. The system may try to save energy by interrupting the connection. In the Device Manager, in the properties of the adapter, you need to uncheck the box from the item "Allow disconnection of this device to save energy."
Comparison of Wireless and Wireless Methods
The choice between WiFi and HDMI cable depends on the specific tasks of the user. Wireless connection wins in convenience and aesthetics, allowing you to quickly show photos from a friend's laptop or launch a presentation. However, for gaming or watching movies in maximum bitrate, cable remains the no-choice leader.
The wired connection ensures no image compression and zero input latency, which is critical for shooters and competitive games. WiFi, even the fastest Wi-Fi 6, always introduces a small compression and latency, imperceptible to the film, but tangible in the game.
For office tasks and home theaters, wireless connectivity to Xiaomi TV is the optimal balance between quality and comfort.Not having to pull long cables across the room keeps the interior and reduces the risk of tripping over wires.
💡
The perfect bundle: Use WiFi for everyday content and presentations, and leave HDMI for console gaming and color work, where 100% pixel accuracy is important.
