Modern Xiaomi Mi TV and Redmi TV are powerful multimedia centers that are often used not only for watching streaming services, but also as large monitors for the PC. Connecting a computer to such a TV opens up a wide range of possibilities: from watching movies on a large screen to conducting presentations and running demanding games. Owners of devices based on Android TV or PatchWall can choose the most convenient method of integration, whether it is a wired connection or wireless synchronization.
The setup process depends on your goals and the equipment available. If you want maximum image quality and minimal input delay, consider cable solutions. Wireless technologies are ideal for fast sharing photos or displaying browser content. In this article, we will discuss all the current methods in detail, help avoid common errors and optimize settings for comfortable work.
Before starting the procedure, make sure that both devices are on and in working order. Regardless of the method chosen, initial diagnosis can save time.It is important to understand that Xiaomi TV runs on the Android operating system, which gives it the advantage of compatibility with most modern standards for video transmission. Let's look at how to properly organize communication between your PC and TV.
Wireless connection via HDMI cable
The most reliable and high-quality way to transmit video is through an HDMI cable, which allows you to stream images in high resolution, up to 4K, and transmit multi-channel audio without delay. You will need a standard HDMI cable, which is bundled with most graphics cards and monitors, or purchased separately.
Connect the output of the graphics card on your computer to one of the HDMI IN ports on the back or side of the TV. After the physical connection, switch the signal source on the TV. Use the remote control, find the source selection button (often denoted as Input or the arrow square icon) and select the appropriate port, such as HDMI 1 or HDMI 2.
If the image doesn't appear automatically, check the display settings in your computer's operating system. In Windows, press the Win + P key combination to select the projection mode. You can duplicate the screen, expand the desktop to the TV or use it as a single display. The cable connection guarantees stable data transfer, which is critical for gaming and watching high-bitret video.
☑️ Verification HDMI connection
It is worth noting that the length of the cable matters. To transmit a 4K signal without loss, it is recommended to use cables no longer than 3-5 meters in length, if they do not have active amplification. Longer segments can lead to image artifacts or complete absence of a signal.
Wireless broadcast via Wi-Fi and Miracast
Miracast technology (often called the Wireless Monitor in Windows) allows you to broadcast your computer screen to your TV without using wires. Since Xiaomi TVs run on Android, support for this protocol is built into the system by default, which makes it easier to set up. Both devices must be connected to the same Wi-Fi network for proper operation.
To start the broadcast on a Windows 10 or 11 computer, press Win + K. On the right side of the screen, the Connect panel will appear. Your Xiaomi TV should appear on the list of available devices. Click on it and the system will try to establish a connection. On the TV screen, a request for confirmation of connection may appear, which must be received by the remote control.
Why is the TV not visible on the list of wireless displays?
The quality of the wireless connection depends on the speed of your Wi-Fi network and signal level. When using a frequency of 2.4 GHz, you can delay and drop the picture quality, especially on busy networks. For comfortable work, you should use the 5 GHz band, which provides higher bandwidth.
It is important to note that wireless broadcasting puts strain on the processor and network, which is ideal for viewing photos, videos from the Internet or working with documents, but for dynamic games, this method may not be suitable due to the inevitable input lag.
Using the Google Home app for broadcasting
Another effective way to display an image from a PC to Xiaomi TV is to use the Google Chromecast built-in ecosystem. Most modern Xiaomi TVs have built-in Chromecast support. To work this method, you will need the Google Chrome browser on your computer and the installed Google Home app (although the browser itself is often enough for a PC).
Open the Google Chrome browser on your computer. Click on the three dots in the top right corner of the menu and select Translate. (Cast.) In the window that opens, you'll see a list of available devices. You can stream a browser tab, an entire desktop or a specific media file. Select your TV from the list.
This method is particularly useful for showing the content of web pages or running video files stored on a hard drive. The system automatically adapts the stream to the network's capabilities. If you choose to broadcast the tab, the sound will also be transmitted to the TV, allowing it to be used as external speakers.
💡
To improve the quality of the broadcast through Chrome, close the unnecessary tabs and heavy applications on the PC to free up the CPU resources for encoding the video stream.
The advantage of using Google Home and Chromecast is that it is highly stable and supports various codecs. Unlike Miracast, which mirrors the screen, Chromecast can take a direct flow of data, which reduces the load on the computer.
Setting the resolution and frequency of screen updates
After successfully connecting your computer to a Xiaomi TV, it is critically important to properly configure image settings.Incorrect resolution or refresh rate can lead to blurred images, black margins at the edges or discomfort when working. 4K-It’s important that Windows understands this.
Go to display settings: Settings → System → Display. Make sure that the native TV resolution is chosen, usually 3840x2160 for 4K models. Also check the refresh rate. For Xiaomi TVs, the standard and most optimal frequency is 60Hz. Some models can support 120Hz, but this will require an HDMI 2.1 cable and a corresponding graphics card.
💡
Properly adjusting 4K resolution and 60Hz frequency is essential for text clarity and smooth mouse cursor when using the TV as a monitor.
In graphics drivers (NVIDIA Control Panel, AMD Radeon Software or Intel Graphics Command Center), you can perform a finer setup. Here it is worth checking the color range (Full or Limited) and color depth. For TVs, the Full range (0-255) is usually better suited to black being really black, not gray.
If you use a TV for games, be sure to activate Game Mode in the settings of the image of the TV itself. This will turn off unnecessary post-processing of the picture and reduce the input delay. Windows can also enable HDR if your TV and graphics card support HDR10, which greatly expands the dynamic color range.
Solving Sound and Delay Problems
A common problem when connecting your PC to your TV is the lack of sound or its de-synchronization with video. By default, Windows can continue to output sound through the built-in laptop speakers or external speakers. To fix this, click on the speaker icon in the tray and select the output device whose name is present Xiaomi or NVIDIA/AMD/Intel High Definition Audio.
If there is sound but it is behind video (or vice versa), the problem may lie in buffering settings or audio format. In the Windows sound control panel, try changing the default format to 16-bit, 44100 Hz or 48,000 Hz. Sometimes higher values cause conflicts with the TV's audio processor.
⚠️ Note: When using Bluetooth adapters on a PC in conjunction with Wi-Fi broadcasting, there may be severe interference, since both devices operate in the 2.4 GHz band. In such cases, it is recommended to use a wired Ethernet network or a USB-Bluetooth adapter carried out on the extension device.
To reduce wireless delays, try to place your router closer to your TV and computer. Using Mesh systems or separate access points can significantly improve connection stability. If delays persist, switching to an HDMI cable remains the only guaranteed solution.
The table below shows the main characteristics of the various connection methods for comparison:
| Method | Image quality | Delay (Latency) | Stability |
|---|---|---|---|
| HDMI Cable | Maximum (4K/8K) | Minimum | Tall. |
| Miracast (Wi-Fi) | Good (depending on the signal) | Medium/High | Medium |
| Google Chromecast | High. | Medium | Tall. |
| DLNA Player | High (video only) | Low (buffering) | Tall. |
Use of DLNA and third-party players
If your goal is not to broadcast a desktop, but to play a movie or photos stored on a computer, the most effective method will be DLNA. Xiaomi TVs have a built-in media player that sees shared folders on the local network. You do not need to broadcast the entire screen, the TV itself decodes the video file.
To set up, open Streaming Media Options in Windows or use third-party software like Universal Media Server or Plex. Add the folders you want to share. On your TV, run the Media Player or Gallery app and you'll see your computer in the source list.
This is the least resource-consuming way to do this: you can turn off your PC monitor or roll the windows, and you can keep the TV playing, and you can also support subtitles and rewinding, which makes it ideal for a home theater.
⚠️ Note: Video formats not supported by the TV's built-in codec (e.g. some variations) HEVC or older audio formats, may not be played through DLNA. In such cases, use third-party players on the TV itself, such as: VLC or MX Player by connecting the hard drive directly or through LAN.
For advanced users, you can install a Plex server on a PC. It not only streams files, but also creates a beautiful shell with posters and descriptions, turning your archive of movies into a personal Netflix. The Plex app for Android TV is available on the Google Play store on your TV.
