How to connect a laptop to a Xiaomi TV: all the ways

Modern multimedia capabilities allow you to turn any laptop into a powerful control center for home theater. Owners of smart TVs Xiaomi Mi TV or Android TV often look for ways to display the image from the computer screen to the large diagonal for watching movies, games or presentations. The process of synchronizing devices can be carried out through physical cables and wireless protocols, giving the user flexibility in choosing use cases.

In this article, we will discuss in detail all current methods of connection, starting from the classical method. HDMI-And you'll learn how to adjust the screen resolution so that the image doesn't stretch, and how to transmit the sound to the outside speakers of the TV. Particular attention will be paid to the nuances of Windows and macOS operating systems with a PatchWall shell or pure Android. TV.

The quality of the connection depends on the chosen method and equipment characteristics. The wired connection guarantees stable transmission of video stream in 4K without delay, which is critical for gamers. Wireless technology, in turn, provides convenience and no unnecessary wires in the interior, although it can be sensitive to interference in the network. To transmit a video stream in 4K resolution at 60 Hz, you need an HDMI cable 2.0 or higher with HDCP 2.2 support.

Connection through HDMI-cable: the classical method

The most reliable and common way to transmit video remains the use of HDMI cable. This interface provides not only high-resolution video stream, but also multi-channel audio, which eliminates the need to connect separate audio cables. To connect, you will need to make sure that both devices have the appropriate ports, which are usually located on the back or side panel of the case.

The physical connection process is simple: one end of the cable is inserted into the laptop connector and the other into the free HDMI IN port on the TV. After connecting, you need to switch the signal source on the TV by pressing the source select button on the remote control and selecting the appropriate input number, for example, HDMI 1 or HDMI 2. The image on the TV screen should appear automatically, but in some cases, you need to manually adjust the display parameters in the computer operating system.

⚠️ Note: It is not recommended to connect or disconnect the cable HDMI, While devices are on, unless you're sure that there's protection against surges in ports. Although the standard supports hot connectivity, static electricity can damage the power controller.

If an image appears but appears incorrect (stretched or black), you need to go to the screen resolution settings. In Windows, this is done through the desktop context menu, selecting Screen Settings. Here, it is important to set the recommended resolution, which usually corresponds to the native resolution of the TV matrix, for example, 1920×1080 or 3840×2160.

💡

Use cables no longer than 3-5 meters long to transmit a 4K signal without amplifiers, as over long distances, picture quality may deteriorate or periodic signal loss.

Wireless connection via Wi-Fi and Miracast

Wireless imaging technology can save space from unnecessary wires and quickly show content from a laptop. The Xiaomi and Windows ecosystems most commonly use the Miracast standard (called the Wireless Display at Microsoft), which allows you to broadcast a screen without the need for a router, creating a direct connection between devices.

To get started, make sure your laptop and TV are connected to the same Wi-Fi network. This is a must for most broadcast protocols to work smoothly. On a Xiaomi TV, you often don’t need to run separate apps, as the signal reception feature is built into the system, but some models may need to open the Wireless Projection or MiraScreen app in the application list.

On a Windows 10/11 laptop, press Win + K. The system will start searching for available wireless displays. Your Xiaomi TV should appear on the list. Once you select the device, a connection confirmation request may appear on the TV screen, which you need to accept by the remote. The connection installation process can take from 5 to 15 seconds.

• 📺 Open the Wireless Projection app on your TV or make sure that Miracast is active in your network settings.
• 💻 On your laptop, press Win. + K or go to "Settings» → «System system» → «Projection on this computer».
• 🔗 Select your Xiaomi TV name from the list of found devices.
• ✅ Confirm the connection on the TV screen if the corresponding notification appears.

It's worth noting that wireless connectivity can be sensitive to interference, and if you see cursor delays or image artifacts, try to get your laptop closer to your router or your TV, and the quality of the broadcast depends on the congestion of the wireless channel, so you can have short-term disconnects in densely built-up apartment buildings.

Setting up image and sound in Windows

After a successful connection, it is often necessary to fine-tune the image output and sound. Windows OS offers several modes of operation with the second screen, which can be switched by a combination of Win + P keys. The choice of the right mode depends on your current tasks: whether it is expanding the workspace or cloning the screen for presentation.

An important aspect is the audio output setting. By default, the sound can continue to play through the speakers of the laptop. To fix this, you need to manually switch the playback device. Click on the speaker icon in the tray (near the clock), select an arrow or the name of the current device and in the drop-down list specify your Xiaomi or Intel Audio TV (if the sound is transmitted via HDMI).

⚠️ Note: If you have connected the cable HDMI No sound, check if the output device in the sound control panel is disabled, and sometimes the system marks the digital outputs as "Disabled", and they need to be activated manually through right-click in the playback window.

For gamers and users working with dynamic content, the screen refresh rate is critical. Make sure that the extended display settings are set to 60 Hz or higher if the HDMI version and the TV matrix allow. Lower frequency can lead to a sense of cursor “viscosity” and less smooth movement.

Broadcast from macOS to Xiaomi TV

MacBook laptop users can also easily connect their devices to Xiaomi TVs, although the algorithm of actions here is somewhat different from Windows.The main protocol for Apple's technology is AirPlay. Many modern Xiaomi TVs with an Android TV shell have built-in AirPlay 2 support, which allows you to broadcast the screen without installing additional software.

If your TV model doesn't support AirPlay natively, you can use third-party apps available in the Google Play store on your TV, such as AirScreen or Receiver for AirPlay. These programs emulate the signal receiver, making the TV visible to the Apple ecosystem. Once you install the app on TV, you just click the Screen Replay icon on the control menu on the Macbook and select the device.

AirPlay transmission quality is usually very high, with minimal delays, making this method suitable even for video content demonstration. However, it is worth remembering that for AirPlay to work, both devices must be on the same Wi-Fi subnet. Using a guest Wi-Fi network or different frequencies (2.4 GHz and 5 GHz with client isolation) can make devices invisible to each other.

• 🍏 Make sure your TV has AirPlay support enabled in settings or an emulator app running.
• 📡 Check that the Mac and TV Connected to a single Wi-Fi network.
• 🖥️ On Mac, click the Screen Replay icon in the menu bar or Control Center.
• 🔐 Enter the code displayed on the TV screen if the system requests confirmation.

Professional color and contrast work when connecting a Mac may require calibration. macOS automatically determines the type of display connected, but sometimes the color gamut may look pale or too saturated. In this case, it is better to adjust through the menu of the TV itself, choosing the Movie or Calibration image mode, since the color settings in macOS are limited when externally connected.

Use of ChromeCast and browser extensions

Another effective way to output content is to use Google Cast technology (Chromecast built-in). Since most Xiaomi TVs run on Android TV, they have a built-in Chromecast module, which allows you to stream Google Chrome browser tabs or content from supported apps directly to the big screen.

To stream your browser tab, open Google Chrome on your laptop, click on the three dots in the top right corner, and select “Translate” (Cast). In the menu that opens, you will see a list of available devices. You can choose to stream a single tab, the entire desktop or a specific file. This method is especially convenient for viewing web pages that do not have full-screen mode on the TV itself.

The advantage of this method is that you can control playback from your laptop, using it as a remote control, so you can pause the video, rewind or change the volume without getting up. 4K-This method may be less stable than direct HDMI-connection, as the video stream is first decoded by the browser, then compressed and transmitted over the network.

Table of comparison of connection methods

To make it easier for you to choose the best way to connect, we have prepared a comparison table that will help you weigh the pros and cons of each method, depending on your needs and available equipment.

And if you look at the table, you can see that for stationary use, like a permanent media center or a gaming space, cable is the leader in stability, and wireless is the choice for mobility and fast access to content.

Addressing common problems

Users can face a number of common problems during the setup process, one of the most common is the lack of image when the cable is connected, in which case you should check if the correct signal source is selected on the TV remote, and often the ports are not numbered in order of location, so you should switch HDMI 1, HDMI 2 and so on.

Another common problem is the desynchronization of audio and video when wirelessly connected, often treated by reducing the load on the laptop processor (closing unnecessary tabs) or switching the router to a less loaded Wi-Fi channel.

⚠️ Note: If the TV can't see the laptop over Wi-Fi, check if the router is enabled with the Guest Network feature. Devices on the guest network are often isolated from the LAN and cannot communicate with each other.

If you have an image, but it's cut around the edges (overscan effect), go to the settings of the TV image. Find the setting "Screen shape", "Share ratio" or "Just Scan" and set the value "Size screen" or "16:9" that will remove the black bezels or cropped edges.

💡

In 90% of cases, connection problems are solved by restarting the router and reconnecting the HDMI cable to another port.
