Using a large screen to work, watch movies or play is a pleasure that is available to every owner of modern tech. Connecting a laptop to a Xiaomi TV via a Xiaomi TV HDMI-cable is the easiest and most reliable way to broadcast a high-quality image without delay. The digital interface allows you to transmit not only a video signal, but also multichannel sound, turning your voice into a digital image. TV full-screen.
Unlike wireless technologies like Miracast or Chromecast, wired connection ensures the stability of the picture even when viewing heavy traffic. 4K-You don't have to worry about signal interruptions or lags during a presentation or movie viewing. - Xiaomi Mi TV and other brand models cope perfectly with the processing of the incoming signal, if you correctly configure the output parameters.
The connection process seems trivial, but users often experience a lack of image or sound due to poor port or resolution choices. In this article, we will take a closer look at all the steps of connecting, from choosing a cable to fine-tuning color and frame rate. The HDMI 2.1 port on Xiaomi TVs often supports eARC, which is critical for transmitting high-quality audio to external audio systems.
Equipment and selection of cables
Before you start connecting devices, you need to make sure that you have the right equipment. The main element here is a cable, the characteristics of which directly affect the quality of the final picture. For modern models of Xiaomi Mi TV Stick or full-fledged TVs with support for 4K and HDR, it is recommended to use high speed or Premium High Speed cables.
If your laptop has an old connector and your TV has only modern ports, adapters may be needed, but it is worth remembering that each additional adapter is a potential point of failure or loss of signal quality. Cheap cables without shielding can cause interference, especially if the wire is longer than 3 meters.
Note the version of the standard, as it defines channel bandwidth. 1.4 is enough for Full HD, but 4K at 60 frames per second and HDR will already require HDMI 2.0 or later. Below is a table of compatibility versions and supported resolutions.
| HDMI version | Maximum authorization | Frequency of personnel | Support for HDR |
|---|---|---|---|
| 1.4 | 4K (3840×2160) | 30 Hz | No. |
| 2.0 | 4K (3840×2160) | 60 Hz | Yes (HDR10) |
| 2.1 | 8K (7680×4320) | 60 Hz/120 Hz | Yes (Dynamic HDR) |
| 2.1a | 8K (7680×4320) | 120 Hz | Yes (full) |
When buying cable, you should not chase the lowest price, because the quality of materials lived and insulation plays an important role. Certified cables often have a label that confirms their compliance with the stated standards of data transfer speed.
Physical connection of devices
The physical connection process starts with looking at the back or side of a Xiaomi TV. Usually, HDMI ports are arranged in groups, and it's important to choose a free connector that you can easily connect to from your laptop. On some models, one of the ports can be labeled (ARC) or (eARC) - it doesn't matter to transfer the image from your computer, you can use any one.
Insert one end of the cable into the laptop port before the characteristic click. HDMI connectors are asymmetrical in shape, so inserting them incorrectly is almost impossible, but you should not put excessive effort either. If the laptop does not have an integrated port, use an external USB-C to HDMI adapter or Thunderbolt.
⚠️ Warning: Never insert or remove the cable HDMI, While devices are on the grid, if you're not sure if you have surge protection, although the standard provides for hot-swap, power surges can damage the port's power controller.
After connecting the cable to the laptop, the second end must be inserted into the selected port on the Xiaomi TV.Remember the port number you used (such as HDMI 1 or HDMI 2), as it will be needed to switch the signal source.
☑️ Checking the physical connection
Setting the signal source on the TV
After the physical connection, you need to switch the TV to external source mode. To do this, take the Xiaomi Remote remote control and find a button with an input image or an Input signature. In some versions of the PatchWall shell or Android TV, this button can be located at the top of the remote or be combined with a menu button.
You'll see a list of available inputs on the screen, and you'll have to select the port number you've connected the cable to, and if the image didn't show up right away, you may not have detected the active device, so try changing the resolution on your laptop or reconnecting the cable.
The source selection interface may look different depending on the firmware version. Sometimes just clicking on the input icon at the top of the home screen will automatically determine the type of device connected and optimize the image settings, although manual adjustments often give the best result.
What to do if the HDMI is gray or inactive?
Display configuration in the operating system
Once the TV is switched to the correct input, the laptop operating system should detect the new display. In Windows 10 and 11, the fastest way to control is the Win + P key combination. Pressing these buttons will open the side menu "Project" where you can select the mode of operation of the screens.
Duplicate mode displays the same picture on both screens, which is convenient for presentations. Expand mode turns the TV into a second desktop, allowing you to drag the windows between the screens. For watching movies, you better choose "Second screen only" to fully use the resources of the graphics card on the large display and turn off the backlight of the laptop matrix.
For deeper customization, including refresh rate and color profile, you need to go to the display settings. In Windows, this is done via Settings → System → Display → Additional display settings. Here, it’s important to make sure the refresh rate is set to 60Hz or higher if your TV and cable support this.
⚠️ Warning: If you see a message saying "Not supported" or a picture twitching, it's likely that the frame rate is too high or the resolution is not supported by the TV.
MacOS owners should also check the settings. In System settings → Monitors, you can adjust the location of the screens and their resolution. Make sure that zooming does not distort the proportions of the image, making the fonts blurry.
💡
The optimal mode for watching a movie is “Only the second screen”, as it reduces the load on the video card and eliminates the desynchronization of frames between monitors of different hertzovka.
Sound tuning and transmission
One of the main advantages of HDMI is the ability to transmit multi-channel audio. By default, the laptop can continue to play audio through its speakers, ignoring the powerful speaker system of the Xiaomi TV. To fix this, you need to manually change the output device.
In Windows, right-click on the speaker icon in the tray and select "Open audio" or "Sounds." In the playback list, find the name of your TV (often the same as the TV model or marked as NVIDIA High Definition Audio, Intel Display Audio).
If the sound appears but the quality seems low, check the audio format. In the playback device properties, you can select bit and sampling frequency on the "Advanced" tab. For most scenarios, the optimal format is 24-bit, 48000 Hz (DVD Quality).
- 🔊 Make sure that the TV remote does not have a button "Mute" and the level of thunder is sufficient.
- 🔊 Check if the sound is turned off in the media player on the laptop.
- 🔊 If you use a receiver, make sure it is switched to the correct input.
In some cases, the sound card drivers may conflict with the HDMI-If there is no sound, try updating the graphics card drivers, as it is often responsible for transmitting the audio stream through the video card. HDMI.
💡
If the sound is wheezing or interrupted, try disabling Sound Improvements in the properties of Windows speakers. Effects processing often creates buffering that leads to audio and video being dissynchronized.
Addressing common problems
Despite the simplicity of the standard, users may encounter various technical difficulties, and one of the common problems is that there is no image when sound is working, which may indicate incompatibility of resolution or HDCP (copy protection). Try lowering the resolution on your laptop to 1920x1080 and check the result.
Another common situation is that the image is not full screen, but with black fields around the perimeter, which is solved through the menu of the Xiaomi TV itself. Press the menu button on the remote, find the image settings and select the zoom mode (Aspect Ratio), which should be called Just Scan, Screen Fit or 16:9, but without trimming the edges.
Screen flickering or periodic signal loss is often associated with poor cable quality or length. If the cable is longer than 5 meters and does not have an active amplifier, the signal may fade, in which case replacing the cable with a better one or using an active repeater helps.
⚠️ Note: If the screen goes out for a few seconds during playback HDR-This can be the process of switching handshake. HDCP 2.2.If this happens frequently, it is possible that your cable is not certified to transmit secure high-definition content.
It's also worth checking your power saving settings. Some laptops turn off the video output to save power if they think the external display is not active. Turn off sleep and set the power circuit to maximum performance.
