Modern multimedia systems make it easy to scale images from handheld devices to large screens. Connecting a laptop to a Xiaomi Mi TV or Redmi TV via an HDMI cable is the most reliable way to transmit video without delay. Unlike wireless technology, a wired connection guarantees stable high-resolution images, which is critical for watching 4K movies or games.
The setup process takes only a few minutes, but requires a certain sequence of actions. HDMI-The cable is the standard cable and the port is working on both devices. If done correctly, the laptop will automatically detect the new display, and you can duplicate the screen or expand the desktop.
In some cases, there may be nuances with graphics card drivers or resolution settings. Windows and macOS have built-in tools for managing external monitors, which we will discuss in detail, and it is worth considering the features of the Android TV interface installed on Xiaomi TVs.
Required equipment and port preparation
Before starting the procedure, make sure you have a serviceable cable. For high-quality image transmission, it is better to use an HDMI 2.0 or higher cable, especially if you plan to view 4K content. Older 1.4 cables may not support high hertz or HDR.
Check the connectors on the laptop case and the back of the TV. Ports can be contaminated or damaged, leading to poor contact. Xiaomi TVs typically use a full-size connector, whereas ultrabooks often feature miniature versions of Mini-HDMI or Micro-HDMI.
💡
Use cables no longer than 3-5 meters long to provide a stable signal without the use of active amplifiers.
If your laptop does not have a classic HDMI port, you will need a special adapter or docking station. This is often found in modern MacBook or Xiaomi Mi Notebook models, where only ports are used. USB Type-C. In this case, you need an adapter. USB-C to HDMI.
- 🔌 Cable HDMI (It is preferable to version 2.0 or 2.1. 4K).
- 💻 Laptop with a serviceable video output.
- 📺 Xiaomi TV with a free port HDMI.
- 🔌 Adapter (if the device ports do not match).
Check if the TV is on and if the right signal source is chosen. Although current systems support Hot Plug, it is recommended to connect the devices first with a cable and then turn them on to avoid power surges.
Physical connection and signal source selection
Insert one end of the cable into the laptop connector and the other into any free port on the TV. Remember the port number you connected to, as Xiaomi TVs may have multiple (e.g. HDMI 1, HDMI 2) This will be needed for further setup.
Once you're connected, turn on the TV. On the remote control, find the source button, which can be called Input, Source, or have an arrow square icon, and press it to open the input menu.
⚠️ Warning: Do not put too much effort into inserting the cable. The connectors must come in tightly but without crunch so as not to damage the contact group inside the TV port.
In the list that opens, select the appropriate port number, such as HDMI 2. If the laptop is on and the cable is working, the desktop or Windows/macOS screensaver should appear on the TV screen.
☑️ Checking the physical connection
Sometimes the image may not appear immediately, in which case you can switch to another port or reconnect the cable. Android TV can recognize a new device for a few seconds, especially if the signal resolution changes.
Configure the display in Windows 10 and 11
Windows automatically detects the connection of a new display. However, for comfortable operation, you often need to manually adjust the screen mode. Press the Win + P key combination to open the project bar.
In the menu that appears on the right, select one of four modes. Duplicate fully copies the image from your laptop to your TV. This is convenient for presentations, but can be inconvenient because of the difference in resolution of the arrays.
To watch movies or games, you should choose Expand mode, in which case the TV becomes the second monitor, and you can drag the application windows to the big screen while continuing to work on the laptop. → System system → Display.
- 🖥️ Computer screen only (image only on laptop).
- 🔄 Duplicate (the same picture on both screens).
- ➕ Expand (TV as a second desktop).
- 📺 Only the second screen (laptop goes out, only TV is running).
It is important to adjust the resolution and refresh rate correctly. In the display menu, scroll down to "Scale and markup." Make sure the TV is the native resolution chosen, usually 1920x1080 or 3840x2160.
If the fonts look blurry, change the zoom. 4K TVs often require a 150% or 200% scale to keep the interface elements from being too small, and this is especially true for 50-inch diagonals.
Configuration of the video output on macOS
MacBook users can also easily connect the laptop to a Xiaomi TV. After a physical connection, go to the system settings via the Apple menu.
macOS will automatically offer options for using an external display, you can choose to mirror or use the TV as a separate desktop, and newer versions of macOS will have monitors controlled in a separate settings window.
⚠️ Note: When connecting a MacBook to a TV via an adapter USB-C Make sure it supports video transmission, not just charging.Cheap cables may not work.
To adjust the resolution, go to the tab of the selected display. Here you can change the refresh rate to 60 Hz or higher if the Xiaomi TV model supports 120 Hz. This will ensure smoothness of the mouse cursor.
Also available in macOS is HiDPI, which improves font clarity. If text on your TV looks unclear, try experimenting with the available resolutions in the Scaled list.
Configure sound transmission via HDMI
HDMI cable transmits not only video, but also digital audio. By default, the computer can continue to play audio through the built-in speakers, ignoring the powerful speakers of the TV, which must be fixed in the system settings.
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 or Android TV and select it by default.
If there is no sound, check the audio device drivers. Often, the video card (NVIDIA, AMD, or Intel) is responsible for transmitting audio over HDMI. Make sure there are no hardware conflicts in the device manager.
Problems with sound codecs
On macOS, audio management is in System settings → Sound → Exit. Select a TV from the list. If the device doesn't show, try restarting the TV with the cable connected.
Table of permission and frequency compatibility
The correct operation of the laptop-TV bundle depends on the coordination of video signal parameters. Below is a table that helps you choose the optimal settings for different models of Xiaomi TV.
| Permission | Frequency (Hz) | HDMI Standard | Recommendation |
|---|---|---|---|
| 1920x1080 (Full HD) | 60 Hz | HDMI 1.4 | Basic mode, works on all TVs |
| 3840x2160 (4K) | 30 Hz | HDMI 1.4 | Maybe sluggish for the cursor. |
| 3840x2160 (4K) | 60 Hz | HDMI 2.0 | Optimal for movies and games |
| 3840x2160 (4K) | 120 Hz | HDMI 2.1 | Only for new game models |
Choosing the wrong frequency can cause the screen to go out with the message "Not supported", in which case wait 15 seconds and the system will return the previous settings, or restart the laptop.
For games, it's important to choose a mode with minimal input latency. On Xiaomi TVs, this mode is often called Game Mode. It automatically activates when you connect consoles, but for PCs, it can be turned on manually in the image settings.
Addressing common problems
If there is an image but it is cropped around the edges (no taskbar visible), the problem is overscan. On a Xiaomi TV, go to the image settings and look for "Screen Format" or "Just Scan." Set "Screen size" or "16:9."
If your laptop can't see the TV, try updating your graphics card drivers. Go to the manufacturer's website (NVIDIA, AMD, Intel) and download the latest version of the software. Old drivers may not work properly with the new HDCP standards.
- 🔌 Check the density of the cable in the connector.
- 🔄 Restart both devices with the cable connected.
- ⚙️ Reset the TV image settings to factory.
- 💻 Update the graphics card drivers on the laptop.
⚠️ Note: If you are connected through HDMI The laptop screen goes off and does not appear on the TV, perhaps the protection against copying content has worked HDCP. Try to launch the right content after connecting.
Sometimes it helps to discharge static electricity. Turn off the TV and laptop, disconnect them from the socket for 1-2 minutes, then connect again. This often solves problems with "hang" ports.
💡
The quality of the cable directly affects signal stability: long cables of poor quality are a common cause of flickering or missing images in 4K.
