Modern multimedia devices allow you to turn a regular TV into a powerful entertainment center, and one of the key use cases is the display of images from your smartphone to the big screen. Owners of the Xiaomi ecosystem often wonder how to establish a high-quality and stable wireless broadcast between a mobile device and the Mi Box or TV Stick. This opens up access to viewing photos, videos, presentations and even games on a diagonal of 50 inches or more without loss of quality.
The setup process can seem complicated only at first glance, since there are several data protocols, each of which has its own characteristics. You do not need to be a technical specialist to understand the nuances of the Mi TV Cast, Miracast or Google Cast. The main thing is to understand what tools to use for your particular operating system, whether it is Android or iOS, and properly prepare the network.
In this article, we will take a look at all the synchronization methods available, from built-in system functions to third-party solutions for complex cases. You will learn how to avoid image delays, why the console may not see the phone, and what router settings affect the speed of video streaming. The key to most methods is to find both devices on the same local Wi-Fi network, which is often overlooked.
Preparation of equipment and Wi-Fi network
Before you start setting up the software, you need to make sure that the hardware is physically ready. Wireless data transfer requires a stable communication channel, so using a guest Wi-Fi network or client isolation networks will lead to failure. Make sure your router supports 802.11n or higher, preferably in the 5 GHz band for high-definition video.
Check that Xiaomi and its smartphone have the latest available system updates.Manufacturers regularly release patches that improve network modules and protocols. DLNA It is also worth rebooting the router if it has been running non-stop for a long time, as this will clear the cache of network spreadsheets and eliminate possible conflicts. IP-address.
⚠️ Note: If your router is giving away two networks (2.4 GHz and 5 GHz) with different names, make sure the phone and console are connected to the same frequency, although in most modern routers with Smart Connect function this is not a critical requirement.
You can use Android built-in tools or third-party snails to test the ping speed to the gateway to diagnose the connection. Low latency is critical for games and interactive applications, whereas standard speed is enough for viewing photos. Don't ignore this stage, because 90% of the connection problems lie in the network infrastructure.
Use of the built-in Mi TV Cast function
The most native way to stream content to Xiaomi devices is through the proprietary Mi TV Cast protocol, which is built directly into the Android TV shell that the Mi Box and TV Stick are equipped with. The app is often already available to run the process on the home screen, or the feature is activated via the Quick Settings menu.
On the smartphone side, you'll need to open a control menu or notification bar and find the Translation, Smart View or Wireless Monitor button. The name may vary depending on the phone manufacturer (Samsung, Xiaomi, Honor, etc.) After scanning the network, your phone should find the Xiaomi Mi TV console in the list of available devices.
☑️ Checking before connection
Once you select a device, you may have a request to confirm your connection on your TV screen, which is a security measure to prevent unauthorized access to your screen, and when you accept the request, you will get a full mirror copy of your smartphone screen, in which mode the phone does not turn off its display, which can lead to increased battery consumption.
| Parameter | Meaning/Description | Impact on broadcasting |
|---|---|---|
| Protocol | Mi TV Cast / Miracast | High compatibility with Android |
| Permission | Up to 1080p/4K | Depends on the power of the console. |
| Delay. | Low/Mediocre | Important for games |
| Sound. | It's synchronous. | It requires a good Wi-Fi signal. |
Google Home (Chromecast built-in)
Because Xiaomi is Android TV-based, it has built-in support for Google Cast technology. This is one of the most stable methods that allows you to stream content from apps that support this feature (YouTube, Netflix, Spotify, etc.), without loading the phone's processor. Unlike mirroring, here the phone acts only as a remote control.
To set up, make sure your smartphone has the Google Home app installed and updated. Open it and find your console in the list of devices. If you want to stream the entire screen, not just content from a particular app, click on the device name and select the "Cast screen" option.
Why does the sound disappear during broadcast?
The advantage of the method is that it can use the phone for other tasks while video is played on the TV, and Chromecast technology provides better picture quality and lower latency than Miracast. However, it requires Google services to work, which can be a limitation in some regions or on modified versions of firmware.

To stream Chrome browser contributions to your TV, click on the three dots in your browser menu and select Translate, then select the tab or the entire desktop.
Broadcast from iPhone and iPad (AirPlay)
Apple device owners should not despair, as modern Xiaomi consoles support the AirPlay 2 protocol.This allows you to stream content from an iPhone, iPad or Mac to a TV without having to buy an Apple TV. The feature is often built into system software, but in some regions may require the installation of an additional receiver application from the Google Play Store on the console.
To start streaming, open Control Point on your iPhone (swipe down from the top right corner or up from the bottom, depending on the model). Click on Screen Replay icon (two rectangles) and select your Xiaomi console from the list. If the devices are on the same network, the connection will be established automatically.
In some cases, you may need to enter a four-digit code that will appear on the TV screen, which is a standard procedure for authorizing a new device, and once confirmed, the smartphone screen will fully appear on the TV, allowing you to show presentations, photos or videos from the gallery.
⚠️ Warning: If the built-in AirPlay support doesn't work, install the "AirScreen" or "AirPin" app on Xiaomi from the app store. They emulate the AirPlay receiver with high accuracy.
Third-party applications for enhanced capabilities
Staff funds are not always enough, especially if you are faced with format incompatibility or want to access the file system of the console. APK-You can install powerful tools such as LocalCast, AllConnect or Web Video Caster.
These apps allow you to stream video files stored in your phone’s memory or on cloud drives (Google Drive, Dropbox) directly to the console, bypassing buffer constraints. They often have their own player that better copes with subtitles and audio tracks of various formats.
- 📱 LocalCast: Ideal for video and photo transfer with support for a wide range of codecs and the ability to control playback from your phone.
- 🌐 Web Video Caster: Allows you to open web pages with video on your phone and send a video stream directly to the console, saving traffic and battery.
- 📂 X-plore File Manager: A powerful file manager with a feature DLNA-server that allows you to share folders of the phone for access from the TV.
Using third-party software provides flexibility, but requires careful permission settings. When you first run the application will request access to media files and the local network — these permissions must be granted, otherwise broadcasting will not be possible. Some applications may contain ads that can be disabled in paid versions.
💡
Third-party apps often solve codec problems that are not supported by standard Android TV tools, ensuring smooth playback of heavy files.
Solving Connection and Delay Problems
Even with the right setup, you can have technical difficulties, and if the console can't see the phone, try temporarily disabling the frequency splitting function on the router, or conversely combining them. IP-addressing both devices so that they are guaranteed to be in the same subnet segment.
Image delays (lag) are often associated with congestion of the Wi-Fi channel by neighboring networks. Use Wi-Fi analysis apps on your smartphone to find the least loaded channel and switch the router to it. Also make sure there are no thick walls or metal structures between the console and the router that shield the signal.
⚠️ Attention: When in use VPN On the phone, the local broadcast may stop working because traffic is going through a virtual tunnel. VPN before the broadcast session.
If the image twitches or crumbles into squares, reduce the output quality in the phone settings (for example, from 4K to 1080p). Also close the background applications on the smartphone, which can consume network resource or CPU time required to encode the video stream in real time.
