Modern multimedia systems allow you to transform your living room into a full-fledged entertainment center, and wireless content transmission is a key element here. Connecting a TV Xiaomi Mi TV or Redmi TV Connecting a PC or laptop to a network cable gives you access to a huge array of files without the need for physical cables. This is especially useful when you need to share a presentation with colleagues, play a movie in high definition, or display photos on a large screen.
Unlike wired HDMI connections, which limit user movement to the length of the cable, Wi-Fi offers freedom of movement. However, to enjoy a stable picture without lag or compression artifacts, both devices must be configured correctly. Wireless network The system must be stable, and the software settings must be correct. In this article, we'll cover all current synchronization methods, from built-in Windows tools to third-party applications.
The setup process may seem complicated only at first glance. In reality, the operating system Android TVThe platform that powers Xiaomi TVs offers extensive integration options with external signal sources. It's important to understand which data transfer protocol is best suited for your needs: streaming video files or full desktop mirroring.
Network requirements and equipment preparation
Before proceeding with software settings, you need to ensure that the physical infrastructure is ready. Wireless connection Extremely sensitive to signal quality and channel bandwidth. If the router is located in another room or behind a thick concrete wall, the quality of the transmitted image may be significantly affected.
The ideal option is to use the 5 GHz band, which provides the high data transfer speeds needed for 4K video streaming. The standard 2.4 GHz band is often congested by neighboring networks and household appliances, resulting in choppy images. screen mirroring.
⚠️ Important: Make sure both your computer and Xiaomi TV are connected to the same router subnet. If you have a dual-band router, make sure the devices aren't on different guest networks or isolated VLANs.
It's also worth checking that the TV's software is up to date. Manufacturers regularly release updates that improve the performance of their modules. Wi-Fi and media transfer protocols. Go to your system settings and check for updates.
- 📶 Make sure the Wi-Fi signal at the TV installation location is above -70 dBm for stable operation.
- 💻 Make sure that network device discovery is enabled on your computer.
- 🔄 Update your TV firmware to the latest available version via the settings menu.
- 🔌 Make sure that AP Isolation is not enabled on your router, which prevents devices from seeing each other.
Translation method via built-in Windows tools (Projection)
The fastest way to display an image from a computer on a Xiaomi TV is to use the built-in protocol. MiracastThis feature is natively implemented in Windows 10 and 11 operating systems and doesn't require any additional software. Xiaomi TVs with Android TV also support this standard, often calling it "Wireless Display" or "Screen Mirroring."
To get started, find the button on your TV remote control that opens the signal sources or apps menu. Launch the "Wireless Display" app or similar, which puts the TV into connection standby mode. After this, the system will become visible to external devices.
On your computer, press the key combination Win + KA "Connection" panel will appear on the right, where your TV should appear in a few seconds. XiaomiClick it, and the system will attempt to establish a connection. If successful, your computer screen will be mirrored on the TV.
☑️ Check before connecting Miracast
It's worth noting that this method creates a direct connection between devices, which can reduce overall internet speed when actively transmitting a heavy video stream. Furthermore, input lag (input lag) can be noticeable when trying to play dynamic games, so this method is more suitable for viewing photos and videos.
Using DLNA technology to play media files
If your goal is not to duplicate your desktop, but simply to watch a movie or listen to music stored on your PC's hard drive, then the technology DLNA It's ideal. It allows the TV to view shared computer folders as network storage and play content natively, without burdening the laptop's processor with video encoding.
In Windows, this feature is called "Media Streaming." To enable it, go to "Settings" -> "Network & Internet" -> "Status." Find "Media Streaming Settings" and enable it. The system will prompt you to select devices that are allowed access—find your device in the list. Xiaomi TV and allow access.
Once set up, open the Media Player or Gallery app on your TV. Select your computer from the list of sources. The folder structure will be displayed the same as on a PC, making it easy to find the files you need.
| Parameter | Description | Recommended value |
|---|---|---|
| Protocol | Data transfer type | DLNA / UPnP |
| Video codec | Compression format | H.264, H.265 (HEVC) |
| Permission | Maximum quality | up to 4K (depending on the router) |
| Audio track | Format support | Dolby Digital, AAC, MP3 |
The main advantage of DLNA is that playback controls (pause, rewind, and volume) are controlled using the TV remote, while the computer can be used for other tasks. However, this method does not support interactive elements of the Windows interface.
Why is DLNA better for 4K movies?
When using DLNA, the TV decodes the video itself using its powerful processor. When using Miracast, the computer must encode the video stream in real time and transmit it, which creates a double workload and can cause lag on weak Wi-Fi connections.
Third-party apps for extended functionality
Standard operating system tools don't always provide the desired quality or compatibility. In such cases, specialized programs developed for the ecosystem come to the rescue. Android TV and Windows. They often handle codecs better and provide a user-friendly management interface.
One of the most popular solutions is the program Let's View or AirDroid CastThey allow you to not only mirror your screen but also control your computer with a remote control, transfer files by dragging and dropping, and even use your phone as a remote control. Installation is completed by downloading the client to your PC and the app from the Google Play Store to your TV.
Another powerful tool is Plex or KodiThese are full-fledged media centers that organize your movie library into a beautiful showcase with posters and descriptions. The server part is installed on your computer, and the client part is installed on your Xiaomi TV.
⚠️ Important: When installing third-party software, pay attention to the permissions the app requests. To work on a local network, they require access to your home network, but access to your microphone or camera is usually not required.
Using specialized software also allows you to bypass some limitations of the Miracast protocol, such as the lack of sound support in some configurations or image scaling issues.
Setting up a projector in Windows: Resolution and frame rate
After a successful connection, a situation often arises where the image on the TV appears stretched or, conversely, has black borders around the edges. This is due to a mismatch between the PC desktop resolution and the native resolution of the TV matrix. Modern Xiaomi TV usually work in resolution 3840x2160 (4K) or 1920x1080 (Full HD).
To fix this, right-click on the Windows desktop and select "Display Settings." Under "Scale and Layout," select the recommended resolution, which is labeled "(Recommended)." You can also adjust the orientation and text scaling here.
An important parameter is the frame refresh rate. For TVs, the standard is 60 HzIf you set a higher value than what your PC monitor supports but your TV does not, the image may disappear or flicker.
In the advanced graphics settings (usually available through the video driver control panel NVIDIA, AMD or Intel) you can adjust the color format. For TVs, the best format is RGB Full or YCbCr 4:4:4, which ensures the most accurate color reproduction without loss of detail in the shadows.
- 🖥️ Always select the "Second screen only" mode if you want to use your TV as your main monitor for movies.
- 🎨 Set the color depth to 8-bit or 10-bit if your graphics card and TV support HDR.
- 🔄 Make sure your PC's power settings are set to "High Performance" to avoid resetting your Wi-Fi connection.
Troubleshooting and connection diagnostics
Despite the ease of setup, users may encounter a number of difficulties. The most common is that the computer simply doesn't see the TV in the list of available devices. In 90% of cases, the problem lies in the Windows network profile settings.
If your network is marked as "Public," Windows blocks device discovery for security reasons. You need to switch the network profile to "Private." You can do this in the Wi-Fi settings by clicking on the properties of your active connection.
Another common issue is audio and video desynchronization or intermittent image freezes. This is a sure sign of insufficient Wi-Fi bandwidth. Switching to the 5 GHz band or moving the router closer to the receiver can help.
⚠️ Warning: Antivirus programs and third-party firewalls (e.g., ESET, Kaspersky, Avast) may block incoming streaming connections. If you experience problems, try temporarily disabling network protection or adding the projector app to the exceptions.
It's also worth checking the "SSDP Discovery Service" in Windows. It should be running and in automatic mode. Without it, DLNA protocols and device discovery won't work.
