Modern smart TVs, especially popular models from Xiaomi with the operating system Android TV, offer a wide range of multimedia interaction options. One of the most popular features is the ability to mirror images from a smartphone directly to a large screen without the need for unnecessary wires. This is convenient for viewing photos, showing presentations, or playing games that don't support standard streaming protocols.
The setup process may seem complicated at first glance, but the technology Wi-Fi Direct Google's built-in features make the task much easier. You don't need to be an engineer to establish a stable connection; you just need to know the correct sequence of actions in your device's menu. In this article, we'll cover all the current methods, from native system tools to specialized software.
The key to successful synchronization is that both devices are on the same local network. If your router broadcasts signals on both 2.4 GHz and 5 GHz frequencies, make sure both the phone and TV are connected to the same access point, as in some cases, isolating clients on different frequencies can prevent devices from being detected.
Preparatory stage: checking the network and updates
Before you begin setting up the broadcast, you need to make sure that your network equipment is working properly. Wireless connection The connection must be stable, as transmitting high-resolution video streams requires significant bandwidth. It is recommended to move closer to the router or use the 5 GHz band to minimize latency.
It's also worth checking that your TV's software is up to date. Manufacturers regularly release patches that improve the performance of communication modules and fix compatibility issues with new versions of mobile OS. To do this, go to Settings → About TV → System update and run the scan.
Don't forget to update the Google Home app and other apps on your smartphone. Older versions of apps may not work correctly with new device discovery protocols on the local network, which could result in your TV simply not appearing in the list of devices available for connection.
- 📡 Make sure both devices are connected to the same Wi-Fi network.
- 🔄 Check for system updates on your Xiaomi TV.
- 📱 Update the Google Home and YouTube applications on your smartphone.
- 🔋 Charge your phone's battery, as broadcasting consumes energy.
Using Chromecast Built-in
The most reliable and high-quality way to transmit content to TVs Xiaomi Mi TV - this is the use of technology Google Cast (Chromecast built-in). This feature is built directly into the Android TV operating system, so no additional software installation is required. This solution is ideal for streaming videos from YouTube, Netflix, and other supported services.
To start broadcasting, open the app on your phone, find the broadcast icon (the rectangle with waves in the corner), and select your TV from the list. The video stream will be transmitted directly from the server to the TV, reducing the load on your smartphone and saving battery life, compared to full screen mirroring.
It's important to note that Chromecast requires an active internet connection on both devices, as the TV automatically downloads content from the link you send it. If the TV doesn't have an internet connection, the feature won't work, even if your phone is connected to a mobile network.
⚠️ Note: If the Chromecast icon doesn't appear in apps, check that Google Cast Receiver is enabled in your TV settings. Sometimes, after a factory reset, it may be disabled by default.
Screen mirroring via Miracast (Broadcast)
If you need to show the contents of the entire smartphone screen, including the desktop, menu, and applications that do not support Cast, you should use the technology MiracastOn Xiaomi TVs, this feature is often called "Casting" or "Wireless Monitor." It creates a direct connection between devices, transmitting a video signal in real time.
To activate, press the Input button on your TV remote and select "Wireless Display" or find the appropriate app in the menu. On an Android smartphone, open the notification shade and look for the "Cast," "Smart View" (Samsung), or "Projection" button. After scanning, select your Xiaomi TV.
To access settings on Android 12+, go to Settings → Connected devices → Connect to PC → Wireless projectionImage quality when using Miracast directly depends on the phone's processor power and Wi-Fi speed. Slight latency is possible, so this method is not recommended for fast-paced games where millisecond response times are critical.
- 📺 Launch the Cast app on your TV.
- 📲 Activate the wireless projector function on your phone.
- 🔗 Select your TV from the list of available devices.
- ✅ Confirm the connection on the TV screen if prompted.
Broadcast from iPhone and iPad (AirPlay on Xiaomi)
For equipment owners Apple Don't worry: modern Xiaomi TVs support the protocol AirPlay 2This allows you to mirror your iPhone or iPad screen as easily as on an Apple TV. No additional receivers are required; everything works via the TV's built-in Wi-Fi module.
To get started, make sure iOS is updated to the latest version. Open Control Center (swipe down from the top right corner or up from the bottom, depending on your model), tap Screen Mirroring, and select your TV. The image will instantly appear on the big screen.
What to do if AirPlay isn't working?
Make sure AirPlay support is enabled on your TV in the settings. Sometimes a TV firmware update is required. Also, check that your router's antivirus software isn't blocking local connections between Apple and Android TV devices.
The AirPlay feature on Xiaomi often requires confirmation via a code that appears on the TV screen upon initial connection. This is a security measure to prevent unauthorized access to your screen by unauthorized people in private homes or offices.
Third-party apps for advanced streaming
Built-in system tools aren't always ideal: they may not support certain video formats or have resolution limitations. In such cases, third-party apps available in the store come to the rescue. Google Play Store on the TV itself. The leaders in this niche are AirScreen, Receiver for Chromecast And ApowerMirror.
The AirScreen app, for example, emulates AirPlay, Google Cast, and Miracast receivers simultaneously, making it a versatile solution for a mixed ecosystem (when you have both Android and iOS devices). After installing it on your TV, simply launch the app and follow the on-screen instructions to connect your phone.
| Application | Supported protocols | Paid version | Peculiarities |
|---|---|---|---|
| AirScreen | AirPlay, Cast, Miracast, DLNA | Yes (Pro) | High stability, 4K support |
| Receiver | Chromecast built-in | No | Simple interface, only for Cast |
| ApowerMirror | Proprietary protocol, AirPlay | Yes (Premium) | Control your phone with a remote control, record your screen |
| LocalCast | DLNA, Chromecast | Yes (Pro) | Better work with local files |
Using third-party software may slightly increase the load on your TV's system. If you notice that the interface Android TV If your TV starts to slow down while streaming through a third-party app, try closing other running background processes on your TV.
Transfer photos and videos via DLNA
To simply view photos or videos stored in your phone's memory, you don't need to duplicate the entire screen. Technology DLNA Allows you to stream media files directly to your TV's player. This frees up your smartphone, allowing you to use it for other tasks while watching.
Most modern Android galleries and video players have built-in DLNA support. Open the video, tap the "Cast" button (the TV icon), and select your Xiaomi TVThe TV will act as a renderer, playing the file, while the phone serves only as a remote control.
This method is especially useful when viewing large video files (4K HDR), which a phone may not be able to handle in real time with full screen mirroring, but which a TV can decode using hardware. In this case, the image quality will be maximized, without compression artifacts.
⚠️ Please note: The DLNA protocol does not support the transmission of Dolby Atmos or DTS:X audio to some TV models without the appropriate license. In such cases, audio may be converted to stereo or not play at all.
Solution and troubleshooting
Despite the simplicity of the technology, users may encounter difficulties. The most common issue is that the TV isn't visible in the device list. In 90% of cases, this is resolved by rebooting the router, as discovery protocols (SSDP) can become stuck when network equipment is running for a long time.
Another common cause is using a guest Wi-Fi network. Routers isolate guest network clients from each other for security reasons, so a phone and TV connected to the "Guest" network simply can't see each other. Switch to your main network.
☑️ Connection diagnostics
If there's a picture but no sound, check the audio output settings on your smartphone. Sometimes the system defaults to audio on the phone, even when the video is playing on the TV. The issue could also be with audio codec formats that the TV doesn't support.
Frequently Asked Questions (FAQ)
Is it possible to broadcast a screen without the Internet, only via a Wi-Fi router?
Yes, Miracast and Wi-Fi Direct don't require internet access; devices connect directly through a router or create their own network. However, for Chromecast and AirPlay, an active internet connection on the TV is critical for the protocol to work.
Why is there a lot of lag when streaming a game?
Wireless video streaming always introduces latency (from 100ms to 1 second). This isn't a big deal for turn-based strategy games, but for shooters or racing games, a wired HDMI connection via a USB-C adapter is better.
Is the sound transmitted to external speakers connected to the phone?
When using Miracast, audio is typically transmitted to the TV. When using Chromecast, audio also goes to the TV. To keep audio on your phone, you need to select the appropriate device in the Bluetooth or audio output settings, but this depends on the specific app.
Does Xiaomi TV support 4K screen mirroring?
Yes, if your router supports the 802.11ac (Wi-Fi 5) or ax (Wi-Fi 6) standard and your smartphone has a powerful processor. However, a very strong Wi-Fi signal is required for stable 4K video.
