Connecting your computer to a Xiaomi TV via HDMI: The Complete Guide

Modern Xiaomi TVs with Android TV or Google TV are powerful multimedia centers capable of broadcasting high quality content. Using them as a monitor for a personal computer or laptop opens up new possibilities: watching movies on a large screen, running demanding games and presenting work projects in high resolution. The main and most reliable interface for transmitting a digital signal remains the HDMI connector, which provides uncompressed video and audio stream.

The process of physically connecting devices often seems simple, but to get the perfect picture without artifacts and delays, you need to consider a number of technical nuances. It is important to choose the right version of the cable, adjust the parameters of the image output in the operating system and correctly set the refresh rate of the screen. In this article, we will discuss in detail all the stages of connection, from choosing equipment to fine-tuning sound and resolution.

Many users are faced with the fact that after connecting the image does not appear or is transmitted without sound, which requires proper diagnosis. We will look at common problems and ways to solve them so that you can enjoy the content without unnecessary difficulties.

Choosing the right equipment and cable

The first step to successfully integrating a PC and TV is choosing the right connection cable. HDMI has come a long way, and for modern Xiaomi TVs that support 4K resolution and HDR, old cables can become a bottleneck. If your computer and TV support a resolution of 3840×2160, using a 1.4 cable will limit the refresh rate to 30 Hz, which will make cursor work and movement in games jittery and uncomfortable.

For comfortable work and games, it is recommended to use HDMI 2.0 or HDMI 2.1 cables. They guarantee enough bandwidth to transmit images to 4K at 60 Hz and above, and also support an extended dynamic range of HDR. When buying, pay attention to the labeling of “High Speed” or “Ultra High Speed”, as cheap counterparts often do not meet the declared characteristics and can cause screen flickering.

Also consider the length of the cable: for distances of more than 3-5 meters, the signal can fade, especially at high resolutions. In such cases, it is better to use active cables or fiber optic solutions that do not lose transmission quality over long distances. The quality of the assembly and shielding also plays a role, especially if the cable is laid near sources of electromagnetic interference.

• 🔌 HDMI 2.1: Perfect for 4K at 120 Hz, supports VRR and eARC for home theater.
• 📺 HDMI 2.0: The best choice for 4K 60 Hz, suitable for most use cases.
• 💻 HDMI 1.4: Supports 4K Only at 30 Hz, acceptable only for static video viewing.

⚠️ Note: Do not try to use adapters. DVI-HDMI or VGA-HDMI without an active signal converter and separate power, unless your PC supports dual analog output mode.

Physical Connection and Port Selection

The connection process begins with examining the back or side panel of your Xiaomi Mi TV. TV. Usually the device is equipped with several ports. HDMI, But they can be different, for example, one of the ports might have a label. eARC/ARC or HDMI 2.1, So, that makes it a priority for connecting a powerful PC or a next-generation gaming console, and connecting to a lower-bandwidth port can limit functionality.

Before connecting, make sure both devices are off or on standby, although HDMI supports hot connectivity, power surges can be unpleasant.Put the cable tightly to the end of the TV port and into the computer's graphics card.If you're using a desktop PC, connect to the connectors on the graphics card, not the motherboard, where the output of the image can be blocked by the processor.

After the physical connection, turn on the TV and use the remote control to switch the signal source. Press the “In” button or select the appropriate source in the menu, for example, HDMI 1 or HDMI 2. At this time, a notification may appear on the computer screen about the connection of the new display, indicating a successful handshake process between devices.

It is important to note that some ports on Xiaomi TVs can only be set to work in enhanced compatibility mode after manually switching in the settings.If the image is missing, try to consistently check each port available, as TV firmware sometimes initializes inputs differently.

Setting up image parameters in Windows

Once the TV is designated as a second monitor, you need to configure the output settings for the best quality. On Windows, go to the Settings → System → Display menu. Here you will see the layout of your screens; if the TV doesn't show, click Discover. Select the Xiaomi TV from the display list to activate the settings menu for it.

The key is to choose how to operate multiple displays: You can duplicate the screen, expand the desktop, or use the TV as the main monitor. For comfortable work and games, the best option is the “Expand these screens” mode, which allows you to drag and drop windows between monitors, or “Second screen only” if the TV is used as the only output medium.

Next, you need to set the correct resolution and refresh rate. Under "Additional Display Settings," select 3840×2160 (if TV 4K) and 60Hz or higher. Make sure the color depth is set to 8 bits or 10 bits if your graphics card and cable support HDR. An incorrectly selected frequency can lead to a black screen or an "Out of range" message.

• 🖥️ Mode: Expand, Duplicate or Only Second Screen.
• 📐 Scaling: Recommended 150% or 200% for 4K TVs when working with text.
• 🎨 Color format: RGB or YCbCr444 font-clear.

Audio system configuration

One of the main advantages of HDMI connectivity is the ability to transmit multichannel audio directly to the TV or a connected speaker system. By default, Windows can continue to output sound through the built-in laptop speakers or connected speakers, ignoring the Xiaomi TV. To fix this, you need to manually switch the playback device.

Right-click on the speaker icon in the tray and select Sounds or go to Sound Settings. In the list of output devices, find your TV's name, which often contains the Xiaomi brand or model designation. Select it and click "Use by default." Now all audio stream, including system sounds and media files, will be directed to the TV.

For users who want high audio quality, it is important to check the sound format in the additional properties of the device. The "Additional" tab allows you to choose bitwise and sampling frequency. For movies and games, the optimal choice will be 24 bits, 48000 Hz (Studio Recording) or Dolby Digital, if your audio system supports decoding.

⚠️ Warning: If the sound is completely gone after switching the device, check the settings of the TV itself. TV Make sure that headphones only or mute mode is not turned on, and check for a level of thunder that could have been set to zero regardless of the system.

In some cases, graphics card drivers (NVIDIA or AMD) have their own sound control panels that can override Windows settings. If standard output cannot be configured, go to the video driver control panel and check the sections associated with audio settings via HDMI.

Specificity of connecting laptops and video cards

Laptop owners often face a limited set of ports where there may be no full HDMI output or only Mini-HDMI. In such cases, the use of quality adapters is critical. Cheap adapters may not support 4K or HDR, turning the picture into a blurry image. Always check the adapter specifications before buying.

For modern ultrabooks equipped with only USB-C or Thunderbolt ports, you need to use a dock or USB-C to HDMI cables. It is important that the USB-C port supports an alternative DisplayPort mode (DP Alt Mode), otherwise video transmission will be impossible. Xiaomi TVs work correctly with such adapters, but require compliance with the sequence of on: first connect the cable to the TV, then to the laptop.

If you have a desktop PC with a discrete graphics card, but you connect to the built-in CPU graphics, you may not get the expected performance in games.Make sure the cable is connected to the horizontal slots on the back of the case where the graphics card connectors are located, rather than the vertical motherboard connectors.

When using external graphics cards (eGPUs) via Thunderbolt, make sure that GPU drivers are updated to the latest version.This is especially true for owners of laptops with Intel Iris Xe or AMD Radeon graphics, where compatibility with 4K TVs sometimes requires patches from the manufacturer.

Table of compatibility and characteristics of ports

To quickly understand your connectivity, we’ll give you a comparative table of the characteristics of different interface versions that can be found in the bundle of your Xiaomi computer and TV, which will help diagnose problems if the image does not meet expectations.

As you can see from the table, for comfortable use of the Xiaomi TV as a monitor, the minimum standard is HDMI 2.0.Only it provides smooth cursor movement and no jerks when playing video. Older versions of the cable are only suitable for static tasks or watching 1080p video.

💡

Using an HDMI 2.0 cable or higher is a must for getting a 4K image at 60Hz on Xiaomi TVs.

Addressing common problems

Even with the right connection, users can face a number of typical problems, such as a lack of signal, incorrect color reproduction or cropped edges of the image. If the TV writes "No signal", try changing the resolution on the computer to a lower one (for example, 1920×1080) to initiate handshake, and then return the desired one.

A common problem is the overscan effect, where the edges of the desktop are hidden outside the screen. On Xiaomi TVs, this is solved in the image settings: find the option “Screen Format”, “Share Ratio” or “Just Scan” and set the value “Screen size” or “16:9 Original”. The graphics card drivers can also have a zoom slider that needs to be moved to the full display of pixels.

If the image looks faded or the colors are distorted, check the color range in the video driver settings. PC monitors typically use the Full range (0-255), whereas TVs often expect Limited (16-235), mismatch of these settings leads to either knocked out white dots or black, dipped in serine. Experimentally select the option in which the gradients look most natural.

⚠️ Note: If you use your TV as a monitor to work with text, turn on Game or PC mode in the Xiaomi image settings. This will turn off unnecessary post-processing and reduce input delay, and also improve font clarity by removing blurring.

In cases where the sound appears, then disappears, the problem may lie in energy saving. USB-ports (if an adapter is used) or drivers. disable selective suspension USB-Port in Windows Power Scheme and Update High Definition Audio Codec Drivers.
