Modern Xiaomi TVs running on Android TV offer users a wide range of multimedia interactions. It is often necessary to display images from the laptop screen to a large display to watch movies, show presentations or run resource-intensive games. Connecting a laptop computer to the Mi TV or Redmi TV panel can be done either through physical cables or wireless data protocols.
In this article, we will take a closer look at all available device synchronization options, focusing on resolution and refresh rate settings, learn how to avoid delays in wireless signal transmission and which cables will provide the best picture quality in 4K HDR. The right configuration of the input signal will unlock the potential of your video system to the maximum.
Whether you’re using Windows, macOS or Linux, the basics of connectivity remain similar, although they have their own software features.We’ll look at the nuances of working with HDMI, USB, and Miracast and DLNA technologies. The ready-made guide will help you quickly connect and enjoy content on the big screen without unnecessary complications.
Wired connection via HDMI interface
The most reliable and common way to transmit high-definition video is to use an HDMI cable.This interface provides uncompressed digital video and audio stream, which is critical for watching movies in high resolution. To connect, you will need a standard cable corresponding to HDMI 2.0 or higher if you plan to broadcast an image at 3840×2160 at 60 Hz.
The physical connection process is simple: one end of the cable is inserted into the laptop output port and the other into any free HDMI connector on the back or side of a Xiaomi TV. After connecting, you need to switch the signal source on the remote control by pressing the input select button (often designated as Input or the arrow square icon) and selecting the appropriate port, such as HDMI 1 or HDMI 2.
If the image does not appear automatically, check the projection settings in your computer's operating system. In Windows, this is done through the Win + P key combination, where you can select the duplicate or expand desktop mode. It is important to make sure that the graphics adapter settings have the native resolution of the TV matrix in place to avoid stretching or blurring the picture.
💡
Use HDMI cables no longer than 3 meters long to provide a stable 4K signal without loss of quality. Long cables of poor quality can cause screen flickering.
It’s worth noting that some ultrabooks and modern laptops may not have a full-size HDMI port. In such cases, you’ll need a video-enabled adapter or docking station. Make sure the adapter supports HDCP 2.2, otherwise secure content from streaming services may be displayed with errors or not run at all.
Wireless screen broadcasting (Miracast and Wi-Fi Direct)
Miracast technology allows you to stream images from your laptop screen to your Xiaomi TV without wires, creating a direct Wi-Fi connection between devices. This feature is built into most modern Android TVs and Windows 8.1, 10 and 11 operating systems. To get started, make sure that both devices are connected to the same wireless network.
On a Xiaomi TV, you need to run a wireless app, often called Wireless Display, Mi Cast, or simply Broadcast in the app menu. Once you start, the TV will go into standby mode. On a Windows laptop, open the notification center, select Connect, and wait for your TV name to appear on the list of available devices.
⚠️ Note: With wireless connection, signal delay (input lag) is possible, which makes this method unsuitable for dynamic shooters, but it is quite suitable for watching videos and working with documents.
The quality of wireless transmission is directly dependent on the load of the Wi-Fi channel and the distance between the router and the devices. For best stability, it is recommended to use a 5 GHz network, which is less susceptible to interference from neighboring networks and household appliances. If the picture twitches, try to bring the laptop closer to the router or reduce the resolution of the output image.
MacOS users may find that the standard AirPlay protocol does not always work correctly with Xiaomi TVs without installing additional software, in such cases, it is recommended to use third-party reciprocating applications available in the Google Play store on the TV that emulate AirPlay reception.
Setting up image and sound parameters
After successfully establishing a connection between a Xiaomi laptop and TV, it is critically important to properly configure output settings.Mismatching resolution or frame rate can lead to incorrect display of colors, black bars at the edges of the screen or no audio. Basic settings are available through the desktop context menu or video driver control panel.
On Windows, go to Settings → System → Display → Additional Display Settings. Here you will see information about current resolution and refresh rate. For Xiaomi HDR-enabled TVs, it is recommended that you activate the Windows HD Color feature so that content with extended dynamic range is displayed correctly.
Special attention should be paid to the audio settings. By default, sound can continue to play through the speakers of the laptop. To switch the audio stream to the TV, click on the speaker icon in the tray, select the output device and find your TV in the list (usually it is displayed as NVIDIA High Definition Audio, Intel Audio or the name of the Xiaomi model).
☑️ Checklist of quality settings
If you use a TV for games, be sure to turn on Game Mode in the image settings of the Xiaomi TV itself.This will turn off unnecessary post-processing effects, reducing input delay. Also, in the control panel (NVIDIA Control Panel or AMD Radeon Software), you can adjust the color range to Full (0-255) for a richer picture.
Using DLNA to reproduce media content
The DLNA (Digital Living Network Alliance) protocol allows you to stream media files (video, photos, music) from a laptop to a TV without the need for full-screen duplication, ideal for watching downloaded movies when computer interface management is not required. Xiaomi TV acts as a renderer, and laptop - as a media server.
To implement this scheme in Windows 10 and 11, you just need to enable the feature “Multimedia Streaming” in the network settings. Once activated in the Video, Music and Images folders, a play icon will appear when you right-click on the file. Select “Play on the device”, you will see a list of available TVs on the network.
More advanced users are encouraged to install a dedicated media server on their laptop, such as Plex or Jellyfin, which not only broadcasts a file, but can also transcode video on the fly if the file format is not supported by the TV, and upload covers, descriptions and subtitles, creating a full-fledged media interface.
| Parameter | HDMI (Wire) | Miracast (Wi-Fi) | DLNA (Streaming) |
|---|---|---|---|
| Image quality | No loss (Lossless) | Compressed (depends on the network) | Original file |
| Delay (Latency) | Minimum | High (100-300 ms) | Low (buffering) |
| Stability | Maximum | Depends on the router. | Tall. |
| Managing the desktop | Complete. | Complete. | Media files only |
In the case of DLNA It's important to keep in mind file formats, although Xiaomi TVs support most popular codecs (H.264, H.265, VP9), Old or rare formats may not play, in such cases, installing a third-party player on a TV, for example, in the case of a computer, VLC For Android or Kodi, solves the compatibility problem.
Solving Common Connection Problems
Even with the right setup, users may encounter technical difficulties. One of the common problems is the lack of image (“No signal”), despite the cable being connected, in which case you need to check whether the HDMI port in the laptop BIOS is active (relevant for some models with hybrid graphics) and whether the connectors are tightly seated in the sockets.
Another common situation is the desynchronization of audio and video when wirelessly connected, often treated by updating the wireless adapter drivers on the laptop and restarting the router, and it is also worth trying to disable the Wi-Fi router's Wi-Fi Multimedia (WMM) function in your settings, although this may reduce the overall priority of multimedia traffic.
Secret Codes for Engineers
If your laptop doesn’t see the TV in the list of wireless displays, check Windows services. Press Win+R, enter services.msc, and find the Wireless Display Service. Make sure it’s running and the type of startup is “Automatic.” The firewall also doesn’t have to block device discovery on a private network.
⚠️ Note: If you are connected through HDMI screen flashes or goes out, maybe the cable lacks bandwidth for the selected resolution.Replace the cable with a certified High Speed HDMI.
