How to connect your computer to a Xiaomi TV: a complete guide

The modern Xiaomi Mi TV is not just a screen for watching air channels, but a full-fledged multimedia center capable of displaying content with high detail. Connecting a desktop computer or laptop to such a display allows you to turn the living room into a cinema or a gaming area with a large screen. Users often look for ways to stream an image from a Windows desktop or macOS to a TV panel for working with documents, watching movies or running demanding games.

There are several proven methods of organizing communication between devices, each of which has its own advantages: wired connection guarantees signal stability and no delays, which is critical for gamers. Wireless technologies such as Miracast or Chromecast provide mobility and no unnecessary wires, allowing you to quickly show photos or videos from anywhere in the room.

In this article, we will take a look at all the connectivity options available, from classic HDMI to advanced networking protocols. You will learn how to adjust screen resolution to make the picture look clear, and how to transfer sound to the external acoustic system of the TV. For high-dynamic games (shooters, racing), using HDMI 2.1 cable is the only way to avoid input lag.

Connecting via HDMI cable: the classic method

The most reliable and common way to image is using an HDMI cable, which transmits digital video and multi-channel audio over a single wire, eliminating the need to pull individual audio cables. The current Xiaomi Mi TV Stick and full-fledged Mi TV P1 series are equipped with HDMI 2.0 or 2.1 ports that support 4K and HDR resolution.

To start the connection, you need to physically connect your computer's graphics card and the free port on the back or side of the TV. Once you connect the power source, the system will automatically detect the new device. If this does not happen, you will need to manually adjust the signal source through the TV menu.

Cable quality plays a major role, especially if you plan to broadcast an image in 4K at 60 frames per second. Cheap cables may not be able to handle high throughput, resulting in screen flickering or no image at all. Use certified High Speed HDMI cables with a bandwidth of at least 18 Gbps.

• 🔌 Take the cable. HDMI and connect one end to the PC graphics card connector and the other to the port HDMI 1 HDMI 2 on TV.
• 📺 Turn on the TV and use the remote to press the source selection button (the icon of the square with the arrow or the button Input).
• 💻 On the computer, press the Win key combination + P (for Windows) and select “Duplicate” or “Extend” mode».
• 🔊 Check the sound settings: if the audio continues to go through the PC speakers, click on the speaker icon in the tray and select the Xiaomi output device TV.

⚠️ Warning: When connecting a hot cable (when devices are on), there is a minimal but real risk of a power surge. It is recommended to connect the cable to the devices turned off first, and only then apply power.

Once the desktop image is successfully connected, it will appear on the big screen. If the image looks stretched or fuzzy, you need to check the resolution settings in the operating system. For game modes, it is also important to activate Game mode in the TV image settings to minimize response delay.

Wireless connection via Wi-Fi and Miracast

Miracast technology (known as Wireless Display Connection on Windows) allows you to broadcast the screen without wires. Xiaomi Android TVs have built-in support for this standard, making the connection process as simple as possible.

For wireless to work, it is critical that both devices are on the same LAN. The router must support the 5GHz standard to ensure sufficient channel capacity. At 2.4GHz, delays and image compression artifacts are possible, especially with dynamic content.

The setup process takes only a few minutes and does not require installing additional software on the TV. Windows 10 and 11 feature built-in by default. macOS uses AirPlay technology for similar purposes, which is also supported by some Mi TV models or through the AirScreen app.

• 📡 Make sure that your Xiaomi PC and TV are connected to the same Wi-Fi network.
• 🖥️ On the computer, press Win. + K to open the wireless display connection panel.
• 📺 In the list of available devices, select your Xiaomi TV.
• ✅ On the TV screen may appear a request for permission to connect – confirm it with the remote control.

If you use Google Chrome, you can stream a separate tab or an entire desktop through the Chromecast feature. This is convenient when you need to show content from a website without loading the computer processor with duplication of the entire OS interface.

Using DLNA to Translate Media Files

The DLNA protocol is designed specifically for sharing multimedia content on a home network, and unlike Miracast, which broadcasts the entire screen, DLNA allows you to send only specific files to your TV, such as movies, music or photos, saving your computer and laptop battery.

To implement this method, the computer must have a media streaming feature enabled. In Windows, this is done through the standard Settings app or through media players like VLC or Kodi. Xiaomi TV acts as a renderer, receiving and decoding the data stream.

The main advantage of DLNA is that it can control playback from the TV remote, so you can pause, rewind or change the volume without going to the computer, and it also supports high-quality audio transmission to your home audio system.

• 📂 Open “Multimedia Streaming Options” in the Windows Control Panel.
• 🔘 Turn on the feature and make sure your Xiaomi is in the right place. TV is on the list of permitted devices.
• 🎬 Open the video file on your computer, right-click and select “Transmit to your device».
• 📺 Select the TV from the list and playback will start automatically.

It's worth noting that DLNA is not suitable for games or for working with the interface of programs. It's only a file protocol. If you plan to use this method often, it's recommended to configure shared folders on your computer to have quick access to the library of movies directly from the TV interface through the Media Player app.

Configure permission and frequency of update

After a physical or wireless connection, it is important to adjust the image output parameters correctly. A mismatch between the computer screen resolution and the native resolution of the TV matrix will lead to blurring or improper scaling of the interface. Most modern Xiaomi TVs have matrices with a resolution of 3840×2160 (4K).

Upgrade frequency is also key: For movies, the standard is 24 or 60 Hz, whereas for PC games, 120 Hz is preferred if the TV model and graphics card support HDMI 2.1. Incorrect settings can cause screen tearing or stuttering.

To set up, go to Screen Settings in Windows. Here you will see two monitors: the main and the detected TV. Select the TV and scroll down to the Display Resolution block. Select the option marked as "(recommended)".

Alternatively, adjust the color range. In the NVIDIA Control Panel (or AMD Radeon Software) settings, change the color range from “Limited” (16-235) to “Full” (0-255), which will make black really black, not dark gray, which will significantly improve the contrast of the picture on OLED or IPS Xiaomi matrixes.

Broadcasting of sound: from PC to TV

Often, after connecting the HDMI cable, the image appears, but the sound continues to go through the laptop speakers or external PC speakers. This is because the operating system does not always automatically switch the default playback device.

Windows 10 and 11 have centralized audio output control, you can switch quickly without restarting your computer or turning off the cable, and it’s also important to check the settings of the TV itself, as some modes (like Game or Movie) may have different audio profiles.

If you use a wireless connection, audio lag can be noticeable. In such cases, the settings of the Xiaomi TV often have a sound synchronization function (AV Sync) that allows you to add artificial video latency to match the audio.

• 🔊 Right-click on the speaker icon in Windows tray.
• 🎛️ Select “Sounds” or go to “Sound Settings».
• 📺 In the list of output devices, find Xiaomi TV or the name of the model (e.g, MI TV 4A).
• ✅ Click on "Use by default».

It's important for audiophiles to know that uncompressed multichannel audio is transmitted through HDMI. If you have a home theater system connected to a TV, make sure that the PC audio settings have Dolby Digital or DTS format chosen if your system supports decoding them. Otherwise, choose PCM for stereo or simple surround sound.

Removal and Connection Problems

Even with high-quality hardware, there are sometimes crashes, the screen may go out, the message "No signal" appears, or the image may twitch, most often the problem lies in incompatibility of versions of HDCP (copy protection) or in the length of the cable.

If the TV can't see the computer, try reconnecting the cable when the devices are off, and check if the HDMI port is selected from the TV's source menu, sometimes the system forgets to activate a particular input after a long downtime.

⚠️ WARNING: If white flashes or “snow” appear on the screen, this is a sure sign of poor contact or poor cable quality. HDMI. Replace the wire with a shorter or higher speed certified.

In case of wireless connection problems, make sure that the antivirus or firewall on your computer does not block device detection on your local network, sometimes temporarily disabling protection to test the hypothesis helps.
