Modern televisions Xiaomi Mi TV While smartphones are powerful multimedia centers, there's often a need to display content from a smartphone on a larger screen. This might be necessary for showing a presentation, viewing photos from a gallery, or playing games with a mobile controller. Wi-Fi wireless data transfer technology eliminates unnecessary cables and allows you to enjoy high-definition content without lag.
The process of synchronizing devices is based on standards Miracast And Google Cast, which are built into the operating system Android TV, used on most Xiaomi TVs. The user doesn't need to be a networking expert to establish a connection, as the interface is extremely simplified. The main requirement is that both devices be on the same local network, which ensures stable data packet exchange.
In this article, we'll cover all connection methods in detail, from built-in system tools to third-party apps. You'll learn how to avoid common pairing errors and why your phone sometimes doesn't detect your TV. We'll also cover the specifics of working with devices based on iOS, as the Apple ecosystem requires a slightly different approach to setup.
Preparatory stage and network requirements
Before you begin setup, you need to make sure your equipment is ready for use. A working router and a stable Wi-Fi signal are essential. If the router is broadcasting at a frequency 5 GHz, the video stream transmission speed will be significantly higher, which is critical for watching 4K video.
Check what's on your TV Xiaomi and the smartphone has the latest software versions installed. Manufacturers regularly release patches that improve the compatibility of data transfer protocols. Go to Settings → About TV → System update and perform the check.
⚠️ Attention: Some routers have a "Guest Network" feature or AP client isolation. If this option is enabled, devices on the same Wi-Fi network will not be able to "see" each other. Make sure both devices are connected to the primary SSID.
It's also worth paying attention to your mobile device's battery. Screen mirroring consumes power, and your phone may drain faster than usual. It's recommended to keep your device close to a charger or use wireless charging, if supported.
Using the built-in "Broadcast" function (Miracast)
The easiest way, which doesn't require installing any additional software, is to use a native Android feature. On Xiaomi, Redmi, and Poco smartphones, it's often called "Broadcast" or "Wireless Monitor." This technology is based on the standard Miracast, which provides a direct connection between screens.
To activate it, open the notification shade on your phone and find the "Broadcast" icon. If it's not in the quick access menu, go to Settings → Connection and Sharing → BroadcastEnable the feature and wait while it searches for available devices.
On the TV side Xiaomi Mi TV You may also need to launch the appropriate application. Depending on the firmware version (PatchWall or pure Android TV), it may be called "Wireless Display," "Miracast," or "Cast." After launching the app on your TV, your smartphone will find it in the list of available devices.
☑️ Checklist for a successful connection
Once connected, the phone's image will be fully mirrored on the TV screen. You can switch between apps, and the image will change in real time. Latency in games is minimal, but depends on the router's signal quality.
Streaming via Google Home and Chromecast
An alternative to Miracast is the technology Google Cast, which is deeply integrated into the Android ecosystem. To use it, you'll need an app. Google Home, which is often pre-installed on smartphones. This method is considered more stable for streaming video from apps.
Launch the application Google Home on your phone. It will automatically scan the network and find your TV. XiaomiClick the device icon to open the control panel. In the bottom menu, select "Cast my screen."
The system will warn you that the image will be broadcast with sound. Confirm the action, and in a few seconds, your phone's screen will appear on the TV. Unlike Miracast, control is handled through Google's cloud servers, which can sometimes reduce latency in poor Wi-Fi conditions.
Why might image quality deteriorate?
When streaming via Google Cast, the video stream is often recompressed to save data. If you notice compression artifacts, try lowering the resolution in the streaming settings or switching to a direct Miracast connection, which transmits a raw video signal without heavy compression.
It's important to note that some apps block the output of protected content (HDCP) via third-party methods, but the official Cast protocol usually works without problems. This is ideal for YouTube, Netflix, and other streaming services.
Features of connecting Apple devices (iOS)
iPhone and iPad owners are faced with the fact that the native AirPlay function does not always work correctly with Android TVs out of the box. However, modern models Xiaomi Mi TV often have built-in AirPlay 2 support. Check for this feature in your TV settings under Settings → AirPlay.
If there is no built-in support or it is unstable, you will need to install a proxy app on your TV. In the store Google Play Store On your TV, find and install the "AirScreen" or "AirPin" app. These programs emulate an Apple receiver.
After installing the app on your TV, open Control Center on your iPhone (swipe down from the upper-right corner) and tap "Screen Mirroring." Your TV should appear in the list. Select it to start mirroring.
| Connection method | Compatibility | Latency | Image quality |
|---|---|---|---|
| Miracast (Standard) | Android | Low | High (no compression) |
| Google Cast | Android / iOS | Average | Optimized |
| AirPlay (via app) | iOS | Low/Medium | High |
| DLNA (via player) | All | No (files only) | Original |
It is worth considering that when using AirPlay emulators on a TV, the load on the processor Xiaomi Mi TV increases. If the interface starts to lag, close other background apps on the TV.
Streaming video from specific apps
Often, users don't need a full screen copy, but just a video preview. Apps like YouTube, Twitch, and online movie theaters have their own broadcast button. Find the icon in the player interface. Cast (rectangle with waves).
Click on it and select yours Xiaomi TV from the list. In this case, the phone acts only as a remote control, and the TV downloads the video directly from the internet. This frees up smartphone resources and allows you to minimize the app or turn off the phone screen without interrupting playback.
For local files stored in your phone's memory, use video players that support DLNA/UPnP, such as VLC for Android or MX PlayerIn the player settings, select "Renderer" or "Playback on Device" and select the TV.
The advantage of this method is that picture quality depends only on the TV's internet speed, not the phone's Wi-Fi network. However, if the router is weak, buffering may still occur.
Solving typical problems and errors
Despite the simplicity of the technology, users often encounter situations where the phone doesn't detect the TV. One of the most common reasons is the use of different Wi-Fi frequencies. Make sure both devices are connected to the same frequency (e.g., both to 2.4 GHz or both to 5 GHz), although modern routers should correctly route traffic between them.
Another issue could be firewall or antivirus settings on your router that block ports needed for device discovery (multicast). Try temporarily disabling packet filtering or the "Network Protection" feature in your router settings to troubleshoot.
⚠️ Attention: The Xiaomi TV menu interface may differ depending on the region (Global, China, EU) and PatchWall version. The layout of settings items may vary, but the operating logic remains the same.
If the connection keeps dropping, try rebooting your router. Running it for long periods of time without powering it down can cause the router's memory buffer to overflow, causing packet loss when streaming video.
Third-party apps for advanced features
Sometimes the built-in functionality isn't enough. For advanced users, there are apps that allow screen sharing with additional settings. For example, Web Video Caster Allows you to send videos from any website directly to your TV, bypassing browser restrictions.
For gamers who want to stream the game with minimal lag, you can try the app ApowerMirrorIt requires installation of the client on both the phone and the TV (via APK file if there's no TV version available in the store). The app allows you to control the phone with a remote, making it convenient for navigation.
Utilities for streaming your PC desktop to a TV via your phone are also worth mentioning, but this requires a cascaded connection and can introduce a noticeable latency. For office presentations, it's better to use a direct laptop connection via HDMI or Wi-Fi Direct.
Why is there no sound during the broadcast?
Most often, the problem is that the source app isn't streaming audio via Miracast, or the wrong audio source is selected on the TV. Check your Android audio settings: Settings → Sound → Sound Output and select a Bluetooth/Wi-Fi device. Also, make sure that the sound on the TV itself isn't muted or in "Video Only" mode.
Is it possible to screencast in audio-only mode?
Yes, if you use apps like YouTube or Spotify, they automatically switch the TV to audio player mode with a screensaver. There's no separate "audio-only" mode for full-screen system streaming, as the video stream is required. However, you can simply turn off the phone's screen backlight, and the audio will continue to play through the TV speakers.
Does broadcasting affect internet speed?
When using Miracast and Wi-Fi Direct, you may not use any internet connection at all, as the data is transferred locally. However, when using Google Cast or online video streaming, the TV consumes data directly, and your internet speed on other devices may decrease, especially when watching 4K content.
