Modern multimedia capabilities allow you to turn a regular laptop or desktop PC into a powerful entertainment center. Connecting your computer to the large screen Xiaomi Mi TV or Xiaomi TV Stick opens up access to high-resolution content, which is especially important for watching movies, presentations or games. Using the HDMI interface remains the most reliable and high-quality way to transmit video signals, providing a stable picture without delay.
The process of physically connecting devices often seems simple, but getting the perfect image requires the right setup both on the Windows operating system and in the menu of the TV itself. Xiaomi, based on Android TV, offers flexible calibration tools that must be activated manually to correctly display colors and resolution. In this article, we will discuss in detail all the steps of connecting, setting up video modes and solving typical problems.
Selection and preparation of equipment for connection
The first step is to assess the technical status of your devices. To successfully transmit the signal, you will need an HDMI cable that corresponds to the port version on both devices. Most modern Xiaomi computers and TVs are equipped with ports of version 2.0 or 2.1, which allows you to broadcast the image in 4K resolution at 60 Hz.
Note the length of the cable: for distances up to 3 meters, a standard copper wire will do, but for longer distances, active cables or fiber optic solutions may be required. HDMI 2.0 and higher cables are mandatory for transmitting 4K HDR signal without artifacts. Poor switching often leads to screen flickering or complete absence of signal.
It’s also worth checking for adapters if your computer doesn’t have an HDMI port built in. Ultrabook owners can use USB-C to HDMI or Mini DisplayPort to HDMI adapters. It’s important that these adapters support the video protocol, not just the data.
Physical connection of devices
The connection process begins with the physical connection of the cable. Before inserting plugs, it is recommended to turn off both devices, although the HDMI standard supports "hot" connection, this can cause a short-term voltage surge or a device definition failure.
Connect one end of the cable to the computer's video output and the other to the selected input on the TV. Remember the port number you've connected to (e.g. HDMI 1 or HDMI 2) as this will be required to switch the signal source. After the connection, turn on the TV and then start the computer.
Windows must automatically detect a new display device. If the screen remains black, manually activate the desired input. To do this, on the Xiaomi remote control, click the source select button, often designated as Input or the arrow square icon.
☑️ Checking the physical connection
Setting up image parameters in Windows
After the image appears on the TV screen, you will likely need to adjust the output settings. Windows allows you to flexibly manage the operation modes of multiple monitors. To access the settings, right-click on the desktop and select Screen Settings.
In the menu that opens, you'll see the layout of the displays. Scroll down to the "Multiple Displays" section. There are four main modes available, each with a different purpose, and the right mode depends on your current tasks: work or entertainment.
- 🖥️ Duplicate: TV image copies the contents of the main monitor, useful for presentations.
- 📺 Expand: The TV becomes an extension of the desktop, allowing you to drag and drop windows between screens.
- 💻 Second screen only: the main monitor goes out, and the entire image is displayed only on Xiaomi TV.
- 🖥️ First screen only: the image from the TV is removed, remaining only on the laptop.
For a more comfortable viewing experience, you can choose either expansion mode or only the second screen, which allows you to run the movie on your TV in full screen mode while you continue to work with documents on your computer, and you can also change the orientation and zoom of the interface in this menu.
Secrets of scaling in Windows
Calibration of permission and frequency of update
Image quality is directly dependent on the right resolution. Xiaomi TVs often have a native resolution of 3840x2160 (4K) or 1920x1080 (Full HD). If Windows has set the wrong value, the image can be stretched or blurred.
To set up, go to the Additional Display settings in the screen menu. This shows the current resolution and refresh rate. Make sure you select a value marked as "(Recommended)". For 4K TVs, it is critical to set a 60Hz frequency, otherwise the interface will appear twitchy.
| Permission | Relationship of parties | Recommended frequency | Quality. |
|---|---|---|---|
| 1920 x 1080 | 16:9 | 60 Hz | Full HD (Standard) |
| 2560 x 1440 | 16:9 | 60 Hz | 2K (Enhanced) |
| 3840 x 2160 | 16:9 | 60 Hz | 4K UHD (Maximum) |
| 4096 x 2160 | ≈19:10 | 60 Hz | DCI 4K (Movie) |
If the desired resolution is not available in the list, your video card or cable may not support the required bandwidth, in which case, try to reduce the refresh rate to 30 Hz or use a higher-end cable, and check the settings of the graphics card drivers (NVIDIA Control Panel or AMD Radeon Software).
💡
Use RGB or YCbCr 4:4:4 in your graphics card settings for the best color rendering of text. Subsampling formats (4:2:0) can make small fonts fuzzy.
Configure sound transmission via HDMI
HDMI interface transmits not only video, but also audio stream. By default, the computer can continue to output sound through the built-in speakers or connected headphones, ignoring the TV. To fix this, you need to change the playback device in the system.
Click on the speaker icon in the Windows tray (bottom right) and select the output device. The list should show the name of your TV, such as Xiaomi TV or Android. After switching, the sound from movies and games will begin to be broadcast through the TV audio system.
⚠️ Note: If you hear a sound but you hear wheezing or interrupting, check the sound format settings. In the playback device properties in the "Advanced" tab, try to reduce the bit or sampling frequency.
In some cases, audio drivers may conflict. If the TV is not displayed in the list of devices, try updating the sound card drivers or reinstalling the graphics card drivers, since audio through HDMI is often processed by a video chip.
Removal and diagnosis
Even with the right connection, there can be technical difficulties, and one of the common problems is that there is no signal or no signal on the TV screen, which is often solved by switching on successively: turn on the TV first, wait for the Android TV system to boot, and then turn on the computer.
Another common problem is black bars at the edges of the screen or, conversely, cropping. This is the Overscan settings. On Xiaomi TVs, go to Settings → Screen and Sound → Image Size and select Precise Scan or Screen Size mode.
- 🔌 Problem: The screen is flashing. Solution: Replace the cable HDMI on a better, shielded.
- 🎨 Problem: Wrong colors. Solution: Check the dynamic range settings (HDR) Windows.
- 🔇 Problem: No sound. Solution: Make sure Windows selects audio output to HDMI, Not on PC speakers.
If the image is missing completely, try connecting your computer to another TV or monitor to rule out a graphics card malfunction. Also helps resetting your TV settings to factory settings through the Settings menu → About System → Reset.
💡
90% of connection problems are solved by replacing the HDMI cable or choosing the right source of the signal (Input) on the TV remote.
Wireless alternative: Miracast and Chromecast
If cable is not possible, Xiaomi TVs support wireless image broadcasting. Miracast technology is built into Windows 10 and 11. To connect, press the Win + K keyboard combination.
The computer will start looking for available displays. Select your Xiaomi TV from the list. The TV screen may have a request for permission to connect, which must be confirmed by the remote control, which is convenient for viewing photos or videos, but can cause delay in games.
⚠️ Attention: Wireless connectivity is highly dependent on the quality of the Wi-Fi network. 4K Make sure that both the PC and the TV are connected to the 5 GHz network.
Alternatively, use Google Chromecast technology built into Android TV. In Google Chrome on your computer, click the menu (three dots) → Broadcast. This allows you to stream a browser tab or the entire desktop to your TV.
