Modern Smart TV turns a normal movie viewing into a full-fledged theater, and it often becomes necessary to broadcast content from the laptop screen to a large diagonal. Owners of Xiaomi and Redmi equipment can use several effective methods to display images from the computer to the TV, this is relevant for watching videos from online cinemas, as well as for presentations or games.
The choice of method depends on the model of your equipment and the availability of free ports. Android TV system installed on Xiaomi TVs supports both wired and wireless data protocols. In this article, we will discuss each option in detail so that you can choose the most suitable for your situation.
Before you start, make sure both devices are on and running. Some methods require you to connect to the same LAN while others operate autonomously. Let's take a look at what tools you'll need to successfully sync.
Connecting via HDMI cable: the classic method
The most reliable and common way is to use an HDMI cable, which allows you to transmit high-resolution video along with multi-channel audio without delay, you'll need a standard cable that you can buy from any electronics store, and the appropriate port on your laptop.
The connection process is as simple as possible and does not require complex software configurations, and once you have a physical connection, the TV automatically recognizes the new signal source, and if this does not happen, you will need to manually change the input source through the remote menu.
For best image quality, it is important to consider the length of the cable and its version. Too long a wire can lead to signal loss, especially at 4K resolution. It is also worth checking whether your laptop supports image output via an HDMI port, since some ultrabooks only use USB-C or Thunderbolt ports.
Here are the main advantages of using a wired connection:
- 🔌 Stable signal transmission without interference and delay.
- 📺 High resolution support to 8K and frame rates of 120 Hz.
- 🔊 Simultaneous transmission of multichannel sound.
- 💻 No need to set up a Wi-Fi network.
☑️ Checking before connection HDMI
If your laptop doesn't have an HDMI port, you'll need a dedicated adapter or docking station, for example, USB-C devices need a USB-C to HDMI adapter, and make sure the adapter is at the right resolution, otherwise the picture may be unstable.
Configure wireless broadcasting via Wi-Fi and Miracast
Wireless technology allows you to get rid of unnecessary wires and broadcast images from a distance. Xiaomi TVs are equipped with a built-in Miracast module (often called the “Wireless Monitor” in Windows), a standard that allows you to transfer video stream directly between devices without a router.
To get started, make sure your laptop and TV are connected to the same Wi-Fi network. In Windows 10 and 11, this feature is built into the system. You don't need to install third-party apps if both devices support the standard.
Open the notification center in Windows and select Connect. The system will start searching for available displays. When your Xiaomi or Redmi TV appears on the list, click on it to pair. The TV screen may have a request for connection permission, which you need to confirm with the remote.
⚠️ Note: With the wireless method, a slight image delay is possible, which is critical for dynamic games, but imperceptible when watching video.
The quality of the wireless broadcast depends on the power of your router and the signal level. If the picture twitches or breaks down into pixels, try to approach the router or lower the resolution in the display settings.
The main parameters for successful wireless synchronization:
- 📶 Stable Wi-Fi connection 5 GHz.
- 💻 Support for Miracast technology in the laptop graphics card.
- 📺 Active function of wireless display in the TV menu.
What to do if your laptop can’t see the TV?
Broadcasting through the Google Chrome browser
If standard methods don't work, Google Chrome is a great solution, and it has a Chromecast feature that allows you to stream a tab or the entire screen to compatible devices. Xiaomi TVs have built-in support for this technology.
To start, open your browser on your laptop and make sure you're on the same Wi-Fi network as your TV. In the upper right corner, click on the three menu points and select "Cast."
In the window that opens, you can choose whether to stream the current tab, the entire desktop, or the audio file. Choose your Xiaomi TV from the list. The image will appear on the big screen almost instantly.
This method is especially useful if you want to show a presentation or video from a specific site, but it is worth considering that broadcasting the entire desktop through the browser can consume more CPU resources.
Comparison of connection methods:
| Parameter | HDMI Cable | Miracast (Wi-Fi Direct) | Google Chrome |
|---|---|---|---|
| Image quality | Maximum (no compression) | High (depending on the signal) | Average (depending on the tab) |
| Delay (Latency) | Absent. | Minimum | Medium |
| Need for a router | Not required | Not required (Direct) | Required. |
| Sound transmission | Yes. | Yes. | Yes. |
Use of Mi Home and Third Party Programs
Xiaomi’s ecosystem offers additional features through the Mi Home app, although its core functionality is sharpened to control the smart home. Screen mirroring is more often used by specialized applications such as LetsView or ApowerMirror, which are installed on both TV and PC.
These programs provide advanced functionality: control of the computer from the remote, recording the screen, transferring files, installation takes place through the Google Play app store on the TV and downloading the client to the laptop.
Once installed, run the app on both devices. They must automatically find each other on the local network. Follow the instructions on the interface screen. Often you need to enter the code displayed on the TV into the program on the computer.
The advantage of third-party software is that it's cross-platform, you can connect not only Windows, but also macOS, which is sometimes difficult to do with standard tools, and they often have more flexible image quality settings.
It is important to keep in mind security when installing third-party software. download applications only from official sources to avoid introducing malicious code into your home network.
Solving Connection Problems
Despite the simplicity of the procedures, users often face difficulties, and one of the most common problems is that the TV doesn't sound when the image is transmitted successfully, so you need to check the settings of the audio device in the operating system.
Right-click on the speaker icon in the Windows tray and select "Open Sound Settings." From the list of output devices, select your Xiaomi TV. If the device doesn't show, try updating the graphics card drivers.
Another common situation is that the image is not full screen or has black margins at the edges. This is solved by adjusting the aspect ratio. On the TV remote, click the image setting button (often designated as "Picture" or menu) and find the option "Format" or "Aspect Ratio." Select "Size screen" or "16:9".
⚠️ Note: If the image is stretched or distorted, check the resolution in the settings of the Windows display. It should correspond to the native resolution of the TV matrix, for example, 1920x1080 or 3840x2160.
If the connection is constantly broken, check the load on the Wi-Fi channel. Downloading large files on other devices can “clog” the channel, causing interruptions to the video stream.
Common mistakes and their solutions:
- ❌ «Device not found" - check if the laptop's Wi-Fi is on and is on the same network.
- ❌ «No signal, replace the cable. HDMI Try another port on the TV.
- ❌ «Black Screen – Make sure you select the correct source of the signal (Input) on the remote control.
💡
Use an HDMI cable no longer than 3-5 meters long to guarantee a stable 4K signal. For longer distances, an active signal amplifier will be required.
Optimize image and sound after connection
After a successful connection, it is important to properly configure the output image. Xiaomi TVs often have image processing modes that can blur text when using the TV as a monitor. Switch to Game or PC mode in the picture settings to reduce input delay.
For a comfortable experience with text and Windows interface, you may need to zoom in, go to the display settings and set the scale to 100% or 125% depending on the diagonal of the TV and the distance to it.
If you use your TV to listen to music or watch movies, make sure that surround mode is on if your audio system supports it. In Windows audio settings, you can select the bit stream format that corresponds to the TV capabilities.
Remember to turn off your laptop screen if you don’t need it to save power. In Windows, this is done by combining the Win + P keys and selecting the “Second Screen Only” mode.
