Using a large screen to watch movies, presentations or games is not just convenient, but often necessary for a comfortable pastime. Xiaomi’s modern Android TVs offer ample multimedia capabilities, but for maximum performance in games or working with heavy files, a wired connection is best used. HDMI cable remains the gold standard for digital signal transmission, providing high-resolution image and multichannel audio without delay.
Connecting a device to a Windows operating system or macOS to a smart TV requires minimal technical knowledge, but users often face the nuances of setting a resolution or selecting a signal source. In this article, we will take a detailed look at each step, from choosing the right cable to fine-tuning the image output parameters so that you can enjoy the content in the best quality without artifacts and desynchronizing audio.
Before you start a physical connection, make sure your laptop has the appropriate video output.Most modern models have an HDMI connector, but ultrabooks often only have USB Type-C or Mini DisplayPort ports, which will require the use of a special adapter or adapter.Cable quality also plays a role: 4K resolution at 60 Hz requires a certified HDMI 2.0 or higher cable, otherwise the system may limit frame rate or color depth.
Equipment preparation and cable selection
The first step is to check the technical compatibility of ports on both devices. The back or side panel of a Xiaomi Mi TV or Redmi TV usually has several inputs, often marked as HDMI 1, HDMI 2 and so on. It is important to remember which port you insert the cable into, since switching between the signal sources will be done by this number.
If your laptop is recently released and doesn’t have a full-size connector, you’ll need an active adapter. Passive adapters may not work with some TV models, requiring external power or specific drivers. When buying a cable, pay attention to the High Speed label, which guarantees enough bandwidth to transmit a high-definition video stream.
The length of the cable should not be excessive, as this can lead to signal attenuation, especially at high resolutions. For distances greater than 3-5 meters, it is recommended to use active signal amplifier cables or fiber optic solutions that ensure stable data transmission without loss of quality.
💡
Use cables no longer than 3 meters long for 4K HDR guaranteed operation, unless the cable has an active signal amplifier.
Physical connection of devices
The connection process starts by turning off both devices, although the HDMI standard supports "hot" connectivity, experts recommend avoiding the risks of power surges. insert one end of the cable into the laptop's video output and the other into the free HDMI port on the Xiaomi TV. Make sure the connector is logged in before the click and sits tight.
When you turn on the TV, select the right signal source. To do this, on the remote control, click the source icon (often looks like a square with an arrow inside) or the Input button. In the menu that appears on the screen, select the port that the cable was connected to, for example, HDMI 1.
- 🔌 Make sure the cable is inserted to the point in the connectors of both devices.
- 📺 Remember the port number. HDMI, Find it quickly in the list of sources.
- 💻 Check if the activity indicator on the laptop port is on (if any).
If a "No signal" message appears on the TV screen, check if the laptop is on and in sleep mode. Sometimes it takes a few seconds for the system to detect a new display and initialize the handshake exchange process. HDCP-key.
☑️ Connection check
Configure the display in Windows 10 and 11
Windows operating systems have a handy toolkit for working with multiple displays. The fastest way to activate the output of the image to the external screen is using hot keys. Press the Win + P combination to call the side menu "Project", where the four main modes are available.
Duplicate mode brings the same picture to the laptop screen and the TV, which is convenient for presentations. Expand mode turns the TV into a second desktop, allowing you to drag windows between screens, which is ideal for multitasking. Second screen only mode turns off the laptop matrix, transferring all the load to the Xiaomi TV, which often improves performance in games.
Nuances of the driver's work
For a deeper setup, go to Settings → System → Display, where you can arrange the screens virtually as they stand in your room so that the mouse cursor moves between them logically, and you can also have zoom and markup in this section, which is critical if the text on the TV looks too small because of the high resolution.
Video Mode Configuration and Resolutions
Image quality is directly dependent on the selected parameters in the settings of the graphics adapter. Xiaomi TVs often support HDR (High Dynamic Range), which extends the dynamic range of brightness and color. To activate this feature, in the advanced settings of the Windows display, you need to enable the option “Use HDR” if your laptop and cable support this standard.
It is important to set the TV’s native matrix resolution, which is usually 3840x2160 for 4K models or 1920x1080 for Full HD. If the resolution is set incorrectly, the image can be stretched, cropped or blurred. The refresh rate also matters: for dynamic content and games, it is preferable to choose 60Hz or higher if the HDMI port and cable version allow it.
| Parameter | Recommended value | Impact on quality |
|---|---|---|
| Permission | 3840x2160 (for 4K TV) | Clarity of details, lack of blur |
| Frequency of update | 60 Hz | Smoothness of cursor movement and video |
| Color format | RGB/Full (0-255) | Saturation and correctness of black flowers |
| Depth of color | 8 bits/10 bits | Smoothness of gradients, lack of posterization |
In the control panel of the video driver (NVIDIA Control Panel, AMD Radeon Software or Intel Graphics Command Center), you can find additional settings. For example, it is important to make sure that you choose the full range of colors (0-255) and not the limited (16-235), otherwise black on the TV screen will look like dark gray and the colors will fade.
💡
Choosing the right color range (full color range)/Full Range is critical for realistic color reproduction on Xiaomi TVs.
Configure sound transmission via HDMI
HDMI cable transmits not only video, but also audio, which allows you to use the TV speakers or the speaker system connected to it instead of the speakers of the laptop. By default, the sound can remain on the computer, so you need to switch it manually. In Windows, right-click on the speaker icon in the tray and select "Sounds" or "Open sound settings".
In the playback list, find your Xiaomi TV or the name of your HDMI chip (like NVIDIA High Definition Audio). Right-click on it and select "Use by default." If the device doesn't show, try updating the hardware configuration or checking the audio codec drivers.
- 🔊 Make sure that the TV settings do not include “Television Speaker Only” if the sound is coming through an external system.
- 🎧 For quality sound, select 24-bit, 48,000 Hz or higher in device properties.
- ⚙️ Check if the sound in the volume mixer of a particular application is turned off.
⚠️ Note: If the cable has lost sound, but there is a video, check if Bluetooth headphones or other peripheral device that could connect automatically are selected as the output device.
Decision and lack of signal
Despite the simplicity of the technology, users often face problems when the TV writes "No signal" or the image twitches. One common reason is a discrepancy in the HDMI version. If you try to output 4K 60 Hz through an old HDMI 1.4 cable, the TV may not receive the signal, in which case reducing the refresh rate to 30 Hz or using a better cable will help.
Video card drivers can also be a source of problems.Outdated software may not correctly detect the problem. EDID-Go to the laptop or graphics card manufacturer's website and download the latest driver version. Sometimes it helps to force the handshake protocol to reboot: turn off the cable when the devices are on, wait 10 seconds and plug again.
If there is an image but it is not on the whole screen (black margins at the edges), this is a zoom problem. In the Xiaomi TV settings, in the Image section, find the Format or the Aspect Ratio option and select Screen Size or 16:9. In the PC video driver settings, this option may be called Scaling and should be set to Full Screen.
⚠️ Note: When using adapters USB-C on HDMI Make sure the port is USB-C The laptop supports an alternative mode DisplayPort (Alt Mode). USB 2.0/3.0 Video transmission is not intended for.
Features of connecting MacBook to Xiaomi TV
Apple laptop owners need to consider the specifics of macOS. Connection will require a USB-C to HDMI adapter or Thunderbolt to HDMI. After physical connection, go to System Settings → Monitors. Here you can configure the location of the screens and select the refresh rate.
macOS may not use the entire screen area of the TV by default because of overscan. To fix this, in some cases you need to rename the display configuration file or use utilities like SwitchResX, but often just select the option “(Native)” or “Screen size” in the TV menu from the permission list.
To transfer audio to macOS, open “Sound Settings” (or via Apple’s menu) and select your Xiaomi TV in the “Output” tab. If the sound wheezes or is interrupted, try lowering the bitrate in advanced settings or checking if the Bluetooth channel is overloaded if wireless devices are running simultaneously.
