Modern Smart TV have become powerful multimedia centers, and the ecosystem Xiaomi Here, it takes the lead thanks to its accessibility and functionality. However, built-in apps are often insufficient, and users often need to stream content from their computer directly to the big screen. This could be a presentation, a high-definition movie, or even a game that requires the maximum screen size for immersion.
The most convenient way to implement such a connection is to use a wireless connection. Wi-FiThis eliminates unnecessary wires, allows you to control content from the comfort of your couch, and maintains the aesthetics of your home. Unlike an HDMI cable, a wireless connection offers more flexibility, although it requires proper configuration of both devices to ensure stable data transmission without lag.
In this guide, we'll cover all available syncing methods in detail, from the standard Miracast protocol to advanced remote control tools. You'll learn how to set up media streaming and avoid common mistakes that often arise when first exploring the options. Android TV based on the platform PatchWall.
Technical requirements and equipment preparation
Before setting up, you need to ensure your infrastructure is ready to handle heavy video streaming. A key requirement is that the computer and TV are on the same local network. This means both devices must be connected to the same router, either via cable or wirelessly.
Pay attention to your network's frequency range. For comfortable viewing of 4K video or game streaming, it's crucial to use the appropriate range. 5 GHzThe 2.4 GHz standard is often overloaded with neighboring networks and household appliances, which leads to image artifacts and audio desynchronization.
It's also worth checking your operating system versions. It's advisable to have the latest build on your PC. Windows 10 or Windows 11, as they have native projection tools built in. TV Xiaomi must have updated firmware, which guarantees support for the latest codecs and security protocols.
- 📡 Make sure both devices are connected to the same subnet (router SSID is the same).
- ⚡ For 4K content, using 5GHz or 6GHz Wi-Fi is highly recommended.
- 🔄 Update the wireless adapter drivers on your computer to the latest version.
- 🛡️ Check that device detection is not blocked in your antivirus or firewall settings.
⚠️ Attention: If your router broadcasts two networks with the same name (Smart Connect) but different frequencies, devices may sometimes "see" each other but not connect. In this case, temporarily separate the 2.4 GHz and 5 GHz networks with different names and connect your devices to one of them.
Miracast Method: Screencasting without installing programs
The fastest way to display an image is to use technology Miracast (In Windows, it's called "Projection"). This protocol allows you to clone your monitor's screen to a TV in real time, transmitting the video stream directly via Wi-Fi Direct, bypassing the router if the devices support this feature, or via a local network.
To get started using the TV remote control Xiaomi You need to find the "Wireless Monitor" or "Wireless Display" app. Depending on your shell version PatchWallIt may have different names, but usually has an icon resembling a signal screen. Once launched, a waiting-for-connection screen will appear.
On a computer with OS Windows press the key combination Win + KThe system will begin searching for available displays. Once your TV appears in the list (usually this is the model Xiaomi TV or Android TV), click on it. The desktop image will instantly appear on the big screen.
☑️ Miracast setup checklist
It's important to understand the difference between the operating modes. "Repeat" mode copies the entire image, making it convenient for demonstrations. "Extend" mode turns the TV into a second monitor, allowing you to drag program windows with the mouse, leaving the main screen free for other tasks.
If the connection is established but the image is choppy or low-resolution, try reducing the image quality in the projection settings. This can sometimes help stabilize the connection in noisy environments.
Why might Miracast not work?
Miracast technology requires support from your graphics card and drivers. If the "Connect to a wireless display" button is missing in Windows, your Wi-Fi adapter may not support Wi-Fi Direct or your drivers may be outdated. In rare cases, this may be blocked by corporate security policies.
DLNA and media streaming over a local network
If your goal is not to duplicate your desktop, but to watch movies or listen to music stored on your PC's hard drive, then the protocol DLNA It's a perfect fit. It allows the TV to view shared computer folders as regular media sources, providing high picture quality without straining the TV's processor.
In the operating system Windows A built-in media server function has been implemented. To activate it, open "Settings" → "Network & Internet" → "Sharing Options." Here, you need to enable network discovery and file and printer sharing.
Next, go to "Streaming Media Settings" in the Control Panel. In the window that opens, you'll see a list of devices on the network. Find yours. Xiaomi TV and make sure the "Allowed" box is checked. Now the "Videos," "Music," and "Pictures" folders will be accessible to the TV.
| Parameter | Description | Recommended value |
|---|---|---|
| Protocol | Data transfer method | DLNA / UPnP |
| Video codec | Stream compression format | H.264 / H.265 (HEVC) |
| Audio track | Audio format | AC3 / AAC / PCM |
| Subtitles | Text accompaniment | SRT / ASS (external) |
To access this data on the TV itself, simply open the Media Player application or any file manager that supports it. SMBSelect your computer from the source list. The folder structure will look the same as on a PC, making it easier to navigate the archive.
The advantage of this method is that playback control (pause, rewind, volume) is carried out entirely from the TV remote control, and the computer can be used for other tasks or even turn off the monitor.
Remote control via TeamViewer and AnyDesk
For more complex scenarios, where you need to not just display an image, but fully control your computer from the couch, using your TV as a monitor, remote access programs are suitable. TeamViewer And AnyDesk have versions for the platform Android TV, on which televisions are based Xiaomi.
First, you need to install the client portion of the program on your TV. This is done through the app store. Google Play Store, available on TV. Find "TeamViewer Host" or a similar app and install it. The corresponding program should also be installed on your computer.
After logging in to your account on both devices, you'll be able to see your PC screen on your TV. The mouse cursor is controlled by the remote, which may feel unusual, but it's quite convenient for navigating the browser or viewing photos. This method is especially useful if you need to share your PC content with someone from another room.
⚠️ Attention: When using remote access programs over the internet (not a local network), traffic goes through the developers' servers. This can reduce image quality and add lag, making this method unsuitable for fast-paced games or watching high-bitrate videos.
There is also specialized software designed for controlling a PC from the couch, for example, Unified RemoteIt turns your TV remote (or smartphone connected to your TV) into an advanced touchpad and keyboard, eliminating the problem of awkward mouse control.
Broadcasting via Google Chrome browser
Browser Google Chrome has a built-in broadcast function that works on the basis of technology Chromecast. Since the operating system of TVs Xiaomi has built-in Chromecast support, this method is one of the most stable for casting browser tabs or the entire desktop.

This method is good because it doesn't require installing any additional software on the TV and works cross-platform. If you're using a laptop with macOS or LinuxWhere there is no native Miracast, Chrome becomes the primary tool for displaying images.
However, it's worth keeping in mind that streaming the entire system through a browser may result in higher input lag than using the Windows system layer. While this isn't noticeable for office work, other methods are better for gaming.
Diagnosing problems and troubleshooting
Despite its apparent simplicity, wireless connections sometimes fail. The most common issue is that the computer doesn't see the TV in the list of available devices. In 90% of cases, this can be resolved by ensuring both devices are on the same subnet and not on the router's guest network, where client isolation prevents data exchange.
Another common issue is audio and video desynchronization. This can be resolved by either reducing the stream quality in the projection settings or rebooting the router. It's also worth checking whether your router has speed limits (QoS) for specific devices.
If the image is present but too dim or has black borders, check the scaling settings on your PC's graphics card.
