Using a Xiaomi TV as a large laptop monitor is a great way to enjoy high-resolution movies, show presentations to colleagues or play games on the big screen. The modern Mi TV and Android TV ecosystem makes it easy to integrate laptops into your home multimedia system. This is most often used by the classic but still relevant HDMI interface, which provides digital video and audio over a single cable.
The connection process is physically simple, but software setting up Windows or macOS operating systems may require attention to detail, you need to choose the right mode of operation of the display and adjust the audio output parameters so that the sound is played through the speakers of the TV, not the laptop. In this article, we will discuss in detail all the stages of connection, from choosing a cable to fine-tuning the screen resolution.
Before you start setting up, make sure your Xiaomi TV is on and running. Also check for free ports on the back or side of the device. Modern models often come with multiple connectors, allowing you to plug in your laptop without turning off other devices like game consoles or TV set-top boxes.
Required equipment and port preparation
To successfully connect, you will need the laptop itself, Xiaomi TV and the corresponding cable. Most modern laptops are equipped with a full-size HDMI port, but ultrabooks can only have compact versions of the Mini HDMI or completely lose the physical connector in favor of a universal USB-C. In the latter case, you will need a special adapter or docking station.
Cable plays a critical role as a transmit signal. To transmit an image in 4K resolution at 60 Hz, you need a certified HDMI 2.0 or higher cable. Using older 1.4 cables may limit the refresh rate of the screen or prevent you from transmitting an image in the high dynamic HDR range.
Note the location of ports on your Mi TV. Often one of the connectors is labeled ARC or eARC. While any port can be used to connect a laptop, using an ARC-enabled port may be preferable if you plan to connect an external speaker system in the future.
⚠️ Note: Do not try to insert or remove the cable HDMI, while the devices are on, unless you're sure there's overload protection. HDMI supports hot connection, voltage surges can theoretically damage the port power controller on the laptop or TV motherboard.
After physically connecting the two devices, switch the signal source on the TV. To do this, use Xiaomi's remote control and find the login select button, often designated as Input or the arrow square icon. In the menu that opens, select the appropriate port, such as HDMI 1 or HDMI 2, where you connected the cable.
Configuring the display in the Windows operating system
After connecting the cable and selecting a source on the TV, Windows usually automatically recognizes a new output device. If the image appears immediately, you are in luck, but often you need to manually adjust the settings for comfortable operation. To quickly access the projection menu, press the Win + P key combination on the laptop keyboard.
In the side menu that opens, you'll have four options for how displays work. Duplicate displays the same picture on both screens, which is convenient for presentations. Expand turns the TV into a second desktop, allowing you to drag and drop windows between screens, which is ideal for multitasking. Second screen only disables the laptop matrix, saving resources and focusing on the large screen.
For more in-depth permissions and refresh rates, right-click on your desktop and select Screen Settings. Here you can select the main display, change orientation and zoom text. If your Xiaomi TV supports HDR, make sure that the Windows HD Color section activates the HDR option to get the best possible picture.
⚠️ Note: If you use the screen expansion mode, the mouse cursor may get stuck at the edge of the laptop monitor, and this is solved by correctly adjusting the location of the displays in the settings menu: Drag the rectangles of the screens so that their position corresponds to the real location of the devices in the room.
An important aspect is refresh rate. For Xiaomi TVs with 60Hz or 120Hz (in gaming models), you need to set the appropriate value in advanced display settings. Incorrect settings can lead to image flickering or no signal. If the image is missing, wait 15 seconds - Windows will automatically return the previous settings if new ones were not confirmed.
Configuration of macOS and MacBook
Apple laptop owners need to consider the interface of macOS. Connecting to a Xiaomi TV with Android TV is similar, but the displays are managed through system settings. Go to System settings and select the Displays section. Here you will see the settings windows for each connected screen.
To switch between operating modes (mirror or desktop extension), newer versions of macOS use the "Setting" tab or the corresponding switch. In mirror mode, the resolution will be limited to the capabilities of a laptop or TV, whichever is lower. In extended desktop mode, each screen can have its own native resolution, which ensures the best picture quality on the Mi TV.
If you’re using a MacBook with Thunderbolt 3/4 ports, make sure the USB-C to HDMI adapter you’re using supports the resolution you want. Cheap adapters are often limited to 30Hz, making cursor movement jittery and uncomfortable. 4K 60Hz requires a cable and an adapter that supports HDMI 2.0 and has a bandwidth of at least 18Gbps.
Why is there no audio on a Mac when you connect to HDMI?
Color rendering on Xiaomi TVs may be different from the usual calibration of Apple displays. In the settings of the macOS display, you can choose a color profile close to HDTV or Video to make the colors look more natural, rather than oversaturated, as it happens in computer mode. It is also worth checking the settings of the TV itself, selecting the Movie or Normal mode of the image.
Configure sound transmission via HDMI
One of the most common problems is the lack of sound after connecting the video. By default, the computer can continue to output audio stream to the built-in speakers or connected headphones. To fix this in Windows 10/11, click on the speaker icon in the tray and select the output device. The list should show your Xiaomi TV or the name of the audio output chip, for example, NVIDIA High Definition Audio or Intel Display Audio.
In macOS, the way to adjust the sound is through System settings -> Sound -> Output. Select the TV from the list. If the sound wheezes or is interrupted, check the sound format settings in the advanced settings of the device. Sometimes changing the bit or sampling frequency in the sound driver control panel helps.
| The problem with sound | Possible cause | Decision |
|---|---|---|
| No sound at all. | Not selected HDMI device | Switch the output of sound to the TV in the OS |
| Quiet sound | Low volume on TV | Increase the volume with Xiaomi remote |
| Sound delay (Lip-sync) | Post-image processing | Turn on the "Game" mode on the TV |
| Crackling or interruption | Bad cable or interference | Replace the HDMI cable with a screened one |
To reduce the latency (lip-sync), which is especially noticeable when watching movies or playing, it is recommended to activate the Xiaomi Game Mode or PC mode on your TV. This mode disables excess post-processing of the image, which also synchronizes the audio stream. In some cases, it helps to disable additional audio enhancements in the drivers of the sound card of the laptop.
Solving Typical Connection Problems and Errors
Despite the simplicity of the standard, users may experience a "No signal" situation, which is often due to a discrepancy between the resolution that the laptop gives and the capabilities of the TV. For example, if the laptop tries to display an image in a non-standard resolution that the Mi TV does not support, the screen will remain black. In this case, you need to change the resolution on the laptop by connecting it to another monitor or using a blind method (press Win + P, then Enter to select the mode).
Another common problem is screen flickering or periodic signal loss, which may indicate poor quality of HDMI cable, especially if it is longer than 3 meters long, long distances require signal amplifier cables, and electromagnetic interference from other wires placed next to the HDMI cable may also be the cause.
☑️ Checklist of diagnostics HDMI
If Xiaomi TV sees a laptop as a device but doesn’t display an image, try updating the graphics card drivers. GPU manufacturers (NVIDIA, AMD, Intel) regularly release updates to improve compatibility with new displays and HDCP standards. Lack of HDCP support can block the display of protected content, such as movies from streaming services.
⚠️ Note: When connecting old laptops with a connector VGA or DVI And remember, through the adapter, these interfaces don't transmit sound. You need a separate 3.5 mm audio cable that connects the output of the laptop headphones to the input. AUX TV (if any) or external acoustics.
Image optimization and game settings
To achieve the best picture quality when watching movies or working with graphics, it is important to correctly adjust the image settings on the Xiaomi TV itself. Go to the image settings and select the mode that suits your task: "Cinema" for movies, "Standard" for working with text and "Game" for minimal input delay. Automated mode often dynamically changes brightness, which can be annoying when working with documents.
If you plan to use a bundle of laptop and Mi TV for gaming, Input Lag becomes a critical parameter. Enable game mode in the TV settings. Some Xiaomi models automatically go into this mode when a signal is detected from a PC, but it is better to check this manually. It is also worth turning off all image "improvers" such as noise reduction and motion smoothing, as they add additional latency.
💡
Use an HDMI cable labeled "High Speed" or "Ultra High Speed." Cheap cables without certification may not be able to handle 4K HDR signal transmission, causing interference or limiting the color gamut to 8 bits instead of 10.
You can use Windows built-in color calibration tools (Calibration of colors search) or online services. On a Xiaomi TV, you can adjust the color temperature (usually "Warm" gives more natural colors for movies) and the range. The right settings will make the picture on the big screen comparable in quality to professional monitors.
💡
The key to quality is not only good cable, but also the right picture mode on the TV. Mode "Cinema" or "Game" gives a more accurate color reproduction and less latency than standard bright modes.
In conclusion, connecting your laptop to your Xiaomi TV via HDMI opens up a lot of possibilities for using the technology. By following the recommendations for choosing cable, setting resolution and audio, you can create a comfortable multimedia environment. Don't be afraid to experiment with the display and sound settings to find the perfect balance for your tasks.
