Connecting your PC to your Xiaomi TV via HDMI cable

The integration of a personal computer and a modern TV offers a huge multimedia experience. Xiaomi Mi TV or Redmi Smart TV displays have high-resolution matrices that can turn a desktop into a theatrical projection. HDMI wired connection remains the gold standard for video transmission, providing a stable picture without the delays typical of wireless technology.

Unlike Wi-Fi broadcasting, cable bundle guarantees minimal input lag, which is critical for gamers and fans of interactive content.You do not have to put up with compression artifacts or sudden breaks of connection while watching heavy video. HDR-The process of pairing devices is physically simple, but the software configuration of the Windows or macOS operating system requires attention to detail.

Before you get to the bottom of the game, you need to make sure that you have the right hardware. Most of today’s Xiaomi graphics cards and TVs are equipped with HDMI 2.0 or later, which allows you to transmit images in a resolution of 3840×2160 with a refresh rate of 60 Hz. The right choice of cable will be the foundation for the quality of the entire system.

Selection of suitable cable and preparation of ports

The quality of the signal transmitted depends on the specification of the conductor used. The market is oversaturated with cables of different classes, and for Xiaomi TVs with support 4K and HDR The usual cheap cables can become a bottleneck. HDMI Premium High Speed.

Note the length of the cord. The standard HDMI signal fades at distances of more than 5 meters without the use of active amplifiers. If your computer is far from the TV, it is better to purchase a quality cable that is 3 meters long than a cheap five-meter analog that may not break through the resolution above 1080p. The ports on the back of the TV are often densely located, so a thick cable can physically interfere with the connection of neighboring devices.

⚠️ Note: Do not try to insert or remove the cable HDMI, While devices are on the grid, unless you're sure there's surge protection in ports. Although the standard implies hot connectivity, surges in static electricity can damage the power controllers on a TV motherboard or PC graphics card.

When you look at the ports on your Xiaomi TV, you will notice that they are often numbered. Remember the port number you connect the cable to, as switching between the signal sources (HDMI 1, HDMI 2) is done using this identifier. Some models have ports that support eARC (Enhanced Audio Return Channel) that are marked with the corresponding logo.

💡

Use flat profile cables if the Xiaomi TV is hanging close to the wall – this will reduce the load on the connector and prevent port breakage.

Physical Connection and Primary Television Setup

Once the cable is selected, switching can be done. Connect one end of the wire to the output of the graphics card on the computer and the other to the free HDMI port on the back or side of the Xiaomi TV. Make sure the connection is tight: the plug must enter before the characteristic click or stop.

Now you need to switch the signal source on the TV. Take the Mi Remote remote control and find the login select button. It can be indicated by the square icon with the arrow or the Input signature. In the menu that opens, select the appropriate port, for example, HDMI 2. If the image does not appear immediately, check if the computer is on and is not in sleep mode.

The Android TV operating system on which Xiaomi TVs are based usually automatically detects a new signal source. The screen should show an image of the desktop or PC boot screen. If you see a message "No signal", try changing the resolution on the computer or reconnecting the cable.

• 🔌 Make sure the cable is inserted to the point in the connectors of both devices.
• 📺 Choose the correct entry number HDMI via the "Sources" menu on the remote.
• 💻 Check that the computer graphics card is active and drivers are installed.
• 🔄 If the screen is black, try turning the TV off and on again.

Sometimes it’s helpful to check the settings of the TV itself. From the Settings → Image menu, you can select Game or PC mode, which reduces post-processing and reduces input latency, especially if you’re planning to use the TV as a monitor for dynamic shooters.

Setting up image parameters in Windows

When the physical connection is established, Windows must recognize the second display. To control the display settings, press the Win + P key combination. The Project sidebar will open, where four main modes of operation are available.

Duplicate displays the same image on both screens, which is convenient for presentations. Expand turns the TV into an extension of your desktop, allowing you to drag and drop windows between monitors. To watch movies or games, you better choose only the second screen to turn off the main monitor and reduce the load on the graphics card.

For more fine-tuning, go to Settings → System → Display. Here you will see the layout of the screens. You can drag the rectangles with your mouse to make the physical location of the monitors match reality - this is important for the cursor to move between the screens correctly. Below, select a Xiaomi TV and scroll down to the "Scale and Markup" section.

Recommended resolution: 3840 x 2160


Update frequency: 60 Hz (or higher if TV supports)




Color depth: 32 bits

It is important to set the native resolution of the TV array. For most Xiaomi models, it is 3840×2160 (4K). If you choose a lower resolution, the picture will be stretched programmatically, which will lead to loss of clarity of fonts and details. Also check the refresh rate: for 60 Hz TVs, installing 30 Hz will make the mouse movement sluggish and unpleasant.

Configuration of audio system via HDMI

Cable HDMI It transmits not only video streams, but also multi-channel audio. By default, Windows can continue to output audio through built-in laptop speakers or connected devices. USB-To activate the acoustic system of the Xiaomi TV or the soundbar connected to it, you need to change the playback device.

Right-click on the speaker icon in the system tray (near the clock) and select "Sounds" or "Open Sound Settings." In the playback list, find your TV. It can be displayed by the model name, for example, Xiaomi TV L55M5-5ARU, or simply as NVIDIA High Definition Audio / AMD HDMI Output.

⚠️ Warning: If after selecting the TV sound is completely lost, check the throttle settings on the remote control itself. HDMI The TV automatically drops the volume level to a minimum or goes into silent sound mode.

For users with high audio quality, you should go to additional device settings. In the speaker properties in the "Additional" tab, you can choose the default format. For surround sound movies, choose 24 bits, 48000 Hz (Studio Recording) or higher if your audio system supports Dolby Atmos or DTS:X.

Solving Common Display Problems

Despite the standardization of the interface, users often face technical nuances, one of the common problems is the lack of image or its periodic blinking, which may indicate a lack of cable bandwidth for the selected resolution and color depth.

If you have a picture, but it is cut at the edges (overscan effect), you need to consult the settings of the TV. In the Xiaomi TV menu, find the Settings section → Image → Screen format (or "Party ratio"). Select the mode "Exact scan", "Scan size" or "Just Scan". This will remove the black bezels and stretch the image over the entire matrix.

Another common situation is broken HDR. Windows 10 and 11 require manual HDR activation for each display. Go to Settings → System → Display → Windows HD Color and turn on the "Use HDR" switch. Make sure the cable is certified for 4K 60Hz, otherwise the option will not be available.

If neither method works, try updating your graphics card drivers. Manufacturers often release patches that improve compatibility with new TVs. It's also worth testing the cable on another device to rule out physical malfunction.

Using the TV as a gaming monitor

For gamers, connecting to Xiaomi’s big screen is an opportunity to immerse themselves in virtual worlds with a new level of detail. However, the larger diagonals make their own adjustments. The key is the Input Lag. In normal image processing mode, the TV can add up to 100ms latency, making it impossible to play shooters.

To minimize lags, be sure to turn on Game Mode. On Xiaomi Android TVs, it often activates automatically when a console or PC is detected, but it's better to check the settings manually. This mode disables heavy noise reduction and motion enhancement algorithms, making the controller's response instantaneous.

If your graphics card supports VRR (Variable Refresh Rate) or FreeSync technology, check their presence in the HDMI specifications of the TV port. Synchronizing the frame rate of the graphics card and the TV matrix eliminates image tearing without increasing latency, which is typical for classic vertical synchronization (V-Sync).

• 🎮 Activate "Game mode" in the settings of the TV image.
• 🚀 Disable all "improvers" pictures in the TV menu to reduce lags.
• 🖥️ Make sure Windows has game mode enabled and background priority reduced.
• 🔋 For wireless gamepads, use USB-Extensioner to avoid interference from TV body.

⚠️ Warning: Long-term static image (e.g., a health strip game interface or Windows taskbar) OLED-Some flagship TVs can burn out pixels. Use screensavers and hide the taskbar when you work long hours.
