Modern technology makes it easy to turn a living room into a full-fledged multimedia center, combining the computing power of a Lenovo laptop and a large Xiaomi TV screen with an Android TV or PatchWall system. This is necessary not only for watching movies, but also for presentations, running resource-intensive games or working with documents on a large canvas. Owners of equipment of these brands often face the question of choosing the optimal interface, since both manufacturers offer a wide range of opportunities for synchronization.
The connection process can be implemented both through physical cables that provide maximum picture quality without delay, and wireless protocols for ease of use. The key here is to properly configure the Windows operating system on the laptop and the Smart TV interface on the display. In this article, we will analyze all the options available, from classic cable to modern broadcast technologies, so you can choose the most suitable for your tasks.
Regardless of the method chosen, pre-prepared devices will save you time and nerves.Make sure the graphics card drivers on Lenovo are updated and the Xiaomi TV software is up to date.This will eliminate 90% of potential compatibility and image resolution issues.
Connecting via HDMI: the classic wired method
The most reliable and common way to transmit video is to use an HDMI cable. This interface transmits high-resolution digital video and audio, providing a stable picture without the compression artifacts characteristic of wireless methods. To implement this method, you will need a standard HDMI-HDMI cable or adapter if your Lenovo laptop is equipped with Mini HDMI or USB-C ports.
The physical connection process is simple: one end of the cable is inserted into the laptop’s output port and the other into any free connector. HDMI IN You can take the remote control and press the signal source button (often referred to as Input or the square icon with the arrow) after you connect, HDMI 1 HDMI 2.
If the image does not appear automatically, you need to configure the output settings in the Windows operating system. Press the Win + P key combination on the laptop keyboard. On the right, the Project menu will appear, where you can select the mode of operation of the screens: duplicate, expand, or use only the second screen.
☑️ Connection check HDMI
It is important to note that when using long cables (more than 5 meters) without an amplifier, the signal can degrade, leading to flickering or complete absence of images. Also pay attention to the version of the standard: for 4K resolution and 60 Hz, it is desirable to use HDMI 2.0 or higher cables labeled as High Speed.
Wireless screen broadcast via Miracast and WiDi
Miracast technology (often referred to as Wireless Display in Windows) allows you to broadcast images wirelessly using a direct Wi-Fi Direct connection between a Lenovo laptop and a Xiaomi TV, ideal for displaying photos, videos or presentations when mobility and no unnecessary cables on the floor are important.
To get started, make sure both devices are on the same Wi-Fi network, although Miracast is not always strictly mandatory, as the connection is often installed directly. On a Xiaomi TV, you need to run a live streaming app. Depending on the firmware version of PatchWall or Android TV, it can be called Translation, Wireless Display, Miracast or Cast.
On the Lenovo laptop side, the action is similar to setting up HDMI, but with the choice of a wireless device: press Win + K or go to the notification center and select Connect. The system will start searching for available displays. When your Xiaomi TV appears on the list, click on it. On the TV screen, you may see a request for confirmation of connection, which you need to receive by the remote control.
⚠️ Note: Wireless broadcasting can cause noticeable delay (latency) of the mouse cursor and video, and this method is not suitable for dynamic games or work requiring high precision movements.
The quality of the wireless image depends on the loading channel and the distance between the devices. If you see jerks or layering of the image, try to approach closer to the router or TV, and also close the background programs that consume traffic.
Why is wireless transmission slowing down?
Using Chromecast built-in technology
Most modern Xiaomi TVs have built-in support for Google Cast (Chromecast) technology, which allows you to stream the contents of tabs of the Google Chrome browser or the entire screen of a Lenovo laptop to the TV. Unlike Miracast, it uses a Wi-Fi network for data transfer, which can be more stable in some scenarios.
To start the broadcast, open the Google Chrome browser on your laptop. Click on the three dots in the top right corner of the menu and select Translate.. (Cast.) In the window that opens, you will see the available devices. If you want to show the contents of a particular tab, just select the TV. To transfer the entire desktop, click Sources and select Translate screen.
The advantage of this method is that it can control playback from a laptop while the TV acts as a monitor, but it is worth remembering that the browser can consume significant CPU resources when encoding a video stream in real time, which can lead to heating of the Lenovo case.
| Method | Image quality | Delay. | Sound. |
|---|---|---|---|
| HDMI | Maximum (Lossless) | Absent. | Multichannel |
| Miracast | Good (compression) | Medium/High | There is. |
| Chromecast | Good (depends on the network) | Medium | There is. |
| DLNA | Original file | No (for video) | There is. |
💡
Chromecast is ideal for watching online video from your browser, but for gaming or work, it’s best to use a wired HDMI connection.
Translation of media files over DLNA
If your goal is not to duplicate the screen, but to play back movies, music or photos saved on a Lenovo laptop on a Xiaomi TV, DLNA technology will be the most effective solution: it allows the TV to see laptop folders as network storage and play content with its own processor without straining the laptop system.
On Windows 10/11, DLNA is built in by default. You need to open Streaming Media Options through the Control Panel or Search. In the window that opens, click "Enable Media Streaming" and make sure your Xiaomi TV is on the list of allowed devices.
Once set up, open the video file on your laptop, right-click it, select Transfer to Device, and specify your TV. Playback will start automatically. For more advanced library management, you can use third-party media servers like Plex or Kodi, which are installed on both PC and TV.
This is especially useful when you want to watch a movie in high bitrate, which can stutter when you live wirelessly broadcast the screen, and the TV itself decodes the stream, ensuring that the picture is smooth.
Control settings from one remote (HDMI-CEC)
One of the most useful features when connecting external devices is HDMI-CEC. This technology allows you to control a laptop or media player connected via HDMI using a remote from a Xiaomi TV, you can switch tracks, pause or even navigate around your desktop without getting up from the sofa.
On Xiaomi TVs, this feature is often referred to simply as HDMI Control or integrated into PatchWall settings. Go to Settings → Device → Device Management (the path may vary slightly depending on the OS version) and activate the switch. On the Lenovo laptop side, additional customization is usually not required if standard HID drivers are installed.
It also allows the TV to automatically switch to the right HDMI input when you turn on the laptop, if it's connected and active, and it creates a single ecosystem where the technology works in concert, but if you have many HDMI devices connected, there may be command conflicts and you have to turn off the function.
⚠️ Note: Not all cables HDMI Supports transmission of control signals CEC, Especially cheap models over 3 meters long. If the feature doesn't work, try replacing the cable with a certified one.
Solution: No signal or sound
Even if you set it up properly, you can have technical difficulties. The most common problem is that you don't have a picture when you have a cable connected. In this case, check if you have the right signal source on your TV. Also try changing the screen resolution on your laptop to a more standard one, like 1920×1080, because some older TV models may not support 4K or specific refresh rates.
If there is an image but no sound, check the audio output settings in Windows. Click on the speaker icon in the tray, expand the list of playback devices, and select your Xiaomi TV (often displayed as a TV model or "NVIDIA/Intel High Definition Audio"). Make sure it is installed by the default device.
In case of wireless connection issues when the TV is not visible on the list, check the firewall and antivirus settings on your Lenovo laptop.They can block incoming connections for Miracast or DLNA protocols. Temporarily disable protection for verification or add an exception for Windows system services.
💡
If the audio is late when wirelessly connected, try changing the default format to 16 bits, 44100 Hz in the Windows sound settings (Control Panel → Sound → Speaker Properties → Additional) this reduces the load on the channel.
