Modern Smart TV Xiaomi TVs, powered by Android TV or Google TV, offer a wide range of multimedia options. One of the most popular scenarios is wirelessly transmitting images and audio from a personal computer to a large screen. This allows for comfortable viewing of movies, photos, and presentations without the need for HDMI cables. WiFi provides sufficient bandwidth to transmit high-definition video if the network is configured correctly.
There are several proven methods for synchronizing devices, each with its own features and advantages. Users can choose between the standard Miracast protocol, built-in Windows operating system tools, or specialized applications for DLNA servers. The choice of a specific method depends on the TV model, the operating system version on the computer, and the required image quality. It is important to understand that all devices must be on the same local network for successful discovery.
In this article, we'll detail the technical nuances of each method so you can choose the best option for your setup. We'll cover both built-in features and third-party solutions that may be required in complex situations. Proper setup will help avoid delays and desynchronization of the audio and video stream. Let's start with preparing the equipment.
Preparing the equipment and WiFi network
Before you begin setup, you need to make sure your local network is ready to handle heavy media content. It's critical that Xiaomi TV, and the computer were connected to the same router. If you are using a dual-band router, it is recommended to use the frequency 5 GHz, as it provides higher speed and connection stability compared to the congested 2.4 GHz band.
Make sure the software on both devices is up to date. On the TV, go to the menu Settings → About TV → System Information and make sure you have the latest available firmware version installed. You should also update your wireless adapter drivers on your computer, as older versions may not correctly support screen sharing protocols.
⚠️ Note: If your router is configured for "Guest Network" mode or AP Isolation, devices will not be able to see each other. To broadcast, you must disable these features in your router settings.
It's also worth paying attention to signal strength. If the TV is located far from the router, the data transfer speed may be insufficient for streaming 4K video. In this case, it's better to use a wired connection or move the router closer to the reception area.
Screencasting using built-in Windows tools
The fastest way to transfer an image from your computer to Xiaomi Mi TV — use a native Windows feature called "Connect." This method is based on technology Miracast, which allows you to broadcast your screen without installing additional software. To get started, press the key combination Win + K on your keyboard or open the notification center and select "Projector".
The system will begin searching for available wireless displays. If the TV is turned on and connected to the same network, its name will appear in the list. After selecting a device, a connection confirmation prompt may appear on the TV screen, which must be accepted using the remote control. This method is ideal for presentations or live desktop sharing.
☑️ Check before connection
However, it is worth considering that wireless image transmission always introduces a small delay, known as latencyThis isn't critical for watching videos, but it may not be suitable for fast-paced games due to the desynchronization of actions and images. In the project settings, you can select "Second Screen Only" to completely switch the image output to the TV.
Using the Projector app on Xiaomi TV
Xiaomi TVs often come pre-installed with a proprietary wireless casting app, sometimes called "Wireless Display," "Miracast," or "Projector." Rather than passively waiting for a connection, launching this app puts the TV into active signal-searching mode. This is especially useful if the standard Windows search doesn't detect the device.
After launching the app, a connection waiting interface will appear on the screen with the device name and sometimes a PIN code. In some firmware versions Android TV You must manually allow connections from unknown devices in the security settings. This mode is often more stable than the background service, as it allocates more system resources to processing the video stream.
If you're using macOS, the built-in AirPlay feature can also work with Xiaomi TVs, but you'll need a receiver app, such as AirScreen, installed on your TV. On Windows, the app on your TV ensures protocol compatibility.
⚠️ Note: The interface and name of the built-in app may differ depending on the regional firmware version (Global, CN, RU). In Chinese versions, the interface may be entirely in Chinese.
Stream media via DLNA and Chrome browser
If your goal is not to duplicate your desktop, but to play a specific video file or photo, it is better to use technology DLNAIt allows you to stream media files directly from your computer to your TV, freeing up your PC's processor. The easiest way is to open the file in Google Chrome, right-click, and select "Cast."
The browser will search for available Chromecast built-in devices, which are included in all Xiaomi TVs. You can cast a single tab or the entire desktop. The advantage of this method is that the TV decodes the video itself using its hardware, which often results in smoother playback.
What to do if Chrome doesn't see the TV?
Make sure IGMP Snooping is enabled in your router settings. Also, try temporarily disabling any antivirus or firewall software that may be blocking local device discovery.
For more advanced media library management, you can use specialized servers like Plex or Kodi. They create a beautiful interface with posters and descriptions, turning your TV into a full-fledged home theater. Install the server on your computer and the client on Xiaomi TV Provides access to all control functions.
Comparison of connection methods and their characteristics
Choosing the optimal connection method depends on your specific needs. Below is a table comparing the key characteristics of the methods discussed. It will help you quickly determine which protocol is best suited to your needs.
| Method | Latency | Picture quality | PC load |
|---|---|---|---|
| Miracast (Win+K) | Low | High (up to 4K) | Average |
| Chrome Cast | Average | Very high | Low |
| DLNA (Players) | Absent | Maximum | Minimum |
| Third-party apps | High | Depends on the network | High |
As the comparison shows, Miracast is better for gaming and work, while DLNA or Chrome Cast are better for watching high-bitrate movies. Third-party apps should only be used if the built-in tools don't work or if you need specific features not available in the default firmware.
Troubleshooting and connection diagnostics
During setup, users may encounter a number of common issues, such as connection drops, no sound, or an inability to find a device. Often, the cause lies in the computer's network adapter power saving settings. Go to Device Manager → Network Adapters, select your WiFi module, open its properties and in the "Power Management" tab, uncheck "Allow the computer to turn off this device to save power."
Another common cause is using different subnets. If your computer is connected to the guest WiFi and your TV is connected to the main WiFi, they won't be able to communicate. Make sure the IP addresses of both devices are in the same range, for example, 192.168.1.x. Restarting the router, which clears the DNS cache and updates the ARP table, also helps.
⚠️ Note: Antivirus programs (Kaspersky, ESET, Avast) often block detection of devices on the local network. If problems occur, try temporarily switching the network profile to "Public" or adding the TV to the exceptions.
If the image is choppy or has low resolution, try lowering the streaming quality in Windows settings or reducing the screen resolution. Your WiFi bandwidth may be limited by interference from neighboring networks or household appliances.
Using third-party apps for advanced features
When standard features aren't enough, third-party solutions come to the rescue. Apps like Let's View, ApowerMirror or TeamViewer allow you not only to broadcast your screen, but also to control your computer with your TV remote. They can be installed on both PCs and Xiaomi TV via Google Play Store.
These programs often offer more flexible quality settings and allow you to stream audio from your computer to your TV even when Miracast fails. However, keep in mind that free versions may have session time limits or watermarks on the image.
For enthusiasts, using ADB (Android Debug Bridge) is also available. By connecting to the TV over the network, you can install apps directly from your computer or mirror the screen via the command line using the Android SDK developer tools. This requires more advanced knowledge, but gives you complete control over the device.
Why can't my Xiaomi TV detect my computer?
The most common issue is that the devices are on different networks (for example, one on 2.4 GHz, the other on 5 GHz with separate SSIDs) or client isolation is enabled on the router. Also, check if Windows Firewall is blocking network discovery.
Is it possible to connect a computer to a TV via WiFi Direct?
Technically yes, but WiFi Direct on Xiaomi TVs is typically used for connecting smartphones (Miracast). For PCs, it's more reliable to use the standard wireless display protocol via a router, as it provides a more stable connection.
How to reduce latency when gaming over WiFi?
It's impossible to completely eliminate WiFi latency. For gaming, we recommend using an HDMI cable. If this isn't possible, make sure your PC is connected to the router via a cable and your TV is within direct line of sight of the router at the 5 GHz frequency.
