Modern Smart TV from the company Xiaomi While Android devices offer users a wealth of multimedia content, built-in apps are sometimes insufficient. You often need to instantly share photos from a family celebration, launch a movie from your smartphone browser, or show a presentation to colleagues on a big screen. Fortunately, the operating system's architecture Android TV, which is the basis for most of this brand's TVs, makes it easy to organize wireless data transmission.
To successfully sync your devices, you don't need complicated cables or adapters—all you need is a stable wireless connection. The entire process takes just minutes if both devices are on the same local network. In this article, we'll cover all the available methods in detail. screen broadcasts, from standard system functions to specialized applications.
Before you begin setting up, make sure your router supports the standard. 802.11ac or newer, which will ensure smooth, high-definition video streaming without lag or compression artifacts. Slow Wi-Fi speeds can cause audio and video to become out of sync, so the quality of network equipment is critical.
Preparing equipment and network
The foundation of any wireless data transfer is a properly configured local network. The first step is to connect and Xiaomi Mi TV, and your mobile phone to the same Wi-Fi network. If you have a dual-band router, it is advisable to use the frequency 5 GHz, as it provides the higher bandwidth required for streaming 4K video.
Please note that some routers have an AP Isolation feature that prevents devices from seeing each other within the network. If devices are connected but can't find each other when searching, check your router's security settings and ensure this feature is disabled. You might also want to update your TV's firmware via the menu. Settings → About TV → System Updateto eliminate software errors.
It's important to keep the distance between devices in mind. Although the Wi-Fi standard is designed to operate over tens of meters, for lossless transmission of a heavy video stream, it's best to be within the same room. Walls and metal structures can significantly weaken the signal, leading to connection interruptions at the most inopportune moment.
⚠️ Note: The menu interface of Xiaomi TVs may differ slightly depending on the operating system version PatchWall or Android TVIf you don't see the item you're looking for, try searching for it in the "Applications" section or using voice search on your remote.
Using Chromecast Built-in
The most popular and convenient method is technology Google Cast, built directly into the TV's operating system. This feature allows you to stream content from supported apps, such as YouTube, Netflix or VK Video, directly, without overloading the smartphone's processor. In this case, the phone acts only as a remote control, and the video stream goes directly from the server to the TV.
To start broadcasting, open the video app on your phone and look for the rectangle icon with waves in the corner of the screen. After tapping the icon, select your channel from the list. Xiaomi TVIf the devices are on the same network, the connection will be established automatically and the video will start playing on the big screen, allowing you to use your phone for other tasks.
Picture quality when using Chromecast is usually higher than when mirroring, as the TV decodes the stream itself. This is especially important for watching high-definition video. 1080p And 4K HDR, where every bit of information matters for the final color rendering.
Screen mirroring via Miracast
When you need to display exactly what is happening on your phone's display, including menus, games, or browsers without Cast support, Cast technology is used. MiracastOn Xiaomi TVs, this feature is often called "Broadcast" or "Wireless Display." It creates a direct connection between the screens, mirroring every pixel in real time.
To activate the mode, go to the TV's signal sources menu or search for the "Cast" app. On an Android smartphone, open the notification shade and select "Cast," "Smart View," or "Project" (the name varies depending on the phone model). After searching for devices, select your TV from the list.
It's worth keeping in mind that when mirroring, the phone's screen must remain on, which can cause it to heat up and drain the battery quickly. Furthermore, this mode has higher input lag, so it may not be suitable for fast-paced games, although it's ideal for turn-based strategy games or photo sharing.

When you first connect, a code may appear on the TV screen that you'll need to enter on your smartphone to confirm the pairing.
AirPlay technology provides a highly stable connection and excellent picture quality. However, if your TV model doesn't have built-in AirPlay support, you can install an app. AirScreen or something similar from the store Google Play Store on the TV itself, which emulates the reception of a signal from Apple devices.
⚠️ Please note: When using AirPlay for gaming or text editing, you may experience a slight delay in cursor or movement. This is a technical feature of the protocol, not a hardware issue.
Third-party streaming apps
When standard methods don't work or advanced features are required, third-party solutions come to the rescue. One of the most popular applications is Web Video Caster or LocalCastThey allow you to stream video files stored on your phone's memory or stream video from browsers that don't have a built-in Cast button.
The principle is simple: you install the receiver app on your TV (via the TV's app store) and the client app on your phone. Once paired, you can select files from your smartphone's memory or enter video URLs, and they will play on your TV. This is a great way to watch videos from "unofficial" sources.
Another powerful tool is the app Xiaomi Mi Remote or universal remotes, which sometimes have the ability to transfer media files over the network. However, specialized video players, such as VLC for Android, often have a built-in "Rendering" function, allowing you to send video to a DLNA-compatible Xiaomi TV in one click.
What should I do if apps don't see my TV?
Make sure the guest network isn't enabled on the router for any of the devices. The devices must be on the main network. Also, try rebooting the router and clearing the DHCP cache.
Comparison of connection methods
Choosing the optimal streaming method depends on your specific goals and content type. To help you organize the information and make your decision, we've prepared a comparison table of the main methods.
| Method | Quality | Delay | Battery consumption |
|---|---|---|---|
| Chromecast | High (up to 4K) | Minimum | Short |
| Miracast | Depends on the signal | Average | High |
| AirPlay 2 | High | Low | Average |
| Third-party apps | Variable | Depends on the codec | Average |
As the table shows, Chromecast is best for watching movies, as it puts the least strain on your phone. For sharing work documents or a photo album, Miracast or AirPlay are ideal. Third-party apps remain the best choice for enthusiasts who want to play video in formats not supported by standard players.
Troubleshooting connection issues
Despite the simplicity of setup, users may encounter difficulties. One common issue is that the TV doesn't appear in the list of available devices. In this case, check if you're using a guest Wi-Fi network, which isolates devices from each other. Restarting the router and both connected devices also helps.
If the video is streaming but constantly buffering or choppy, try lowering the playback quality in the source app settings. The Wi-Fi signal may be too weak where the router is located. In such cases, using a Wi-Fi repeater or switching to a wired connection to the TV via a LAN cable can dramatically improve the situation.
Sometimes the audio may lag behind the video. This can be resolved by restarting the app on the TV or updating codecs in third-party players. It's also worth checking if there are any heavy processes running in the background on your phone that are consuming bandwidth.
⚠️ Note: Router specifications and TV firmware are regularly updated by manufacturers. If the menus described appear different, please refer to the official documentation for your specific model or update the firmware to the latest version.
Why is there no sound during the broadcast?
Often, the problem is that "Do Not Disturb" mode is enabled on your phone or the audio is routed to a Bluetooth headset. Check your audio output settings in Android or iOS.
Is it possible to stream video via mobile Internet (4G/5G)?
Technically, this is possible, but only if the TV and phone are on the same virtual network, which requires complex router configuration. Standard methods (Cast, Miracast) only work on a local Wi-Fi network. For viewing over a mobile internet connection, it's better to use the built-in apps on the TV itself.
Does broadcasting affect internet speed?
Yes, when streaming video (especially 4K), the Wi-Fi channel can be heavily loaded. If someone starts downloading large files or playing online games at the same time, lag is possible on both the TV and other devices.
Why is the picture not full screen?
This depends on the aspect ratio of the content being streamed and your TV settings. Try changing the display mode on your Xiaomi remote (the button with the rectangle icon or in the "Picture Settings" menu) to "Screen Fit" or "16:9."
Is it safe to use third-party streaming apps?
Using popular apps from the official Google Play store on your TV is safe. However, avoid installing APK files from untrusted sources, as they may contain malicious code that can steal your home network data.
