Modern multimedia set-top boxes are turning a regular TV into a full-fledged entertainment center, making it easy to stream content from mobile devices. Output from your phone to the big screen through the Xiaomi Mi Box has become the standard for watching movies, presentations and mobile games. Users often look for quick ways to share photos from the gallery or launch videos from a streaming service without getting confused in the wires.
The Android TV ecosystem, which is the foundation of the Mi Box S and newer models, offers a variety of native synchronization tools. You don’t need to be a tech person to customize high-resolution images. In this article, we’ll look at all the current techniques, from the built-in Cast feature to using third-party apps that provide minimal latency.
The quality of the data transfer depends on the stability of the wireless connection and the version of the console software. Before you start setting up, make sure that your Xiaomi device is connected to a Wi-Fi network with sufficient bandwidth. This is a critical point, since streaming video in 4K requires a significant amount of traffic for smooth playback without buffering.
Preparation of equipment and network for stable operation
The foundation of successful broadcasting is the correct organization of the local network: both devices — smartphone and media player — must be on the same subnet, that is, be connected to the same router. If you are using a guest Wi-Fi network or 2.4 GHz band in the presence of 5 GHz, the data rate may not be sufficient for the user to use the mobile phone. HD-content.
Check the firmware on your Xiaomi Mi Box. Manufacturers regularly release updates that improve Miracast protocols and fix connection errors. To check, go to the system settings menu and select the software update. Outdated software often becomes the reason why the phone does not see the console in the list of available devices.
⚠️ Note: Using mobile hotspots (spreading internet from your phone) to connect the console may not work for the screen broadcast function, as some operators block ports necessary for local device detection.
Also worth paying attention to the screen resolution that your TV supports. Xiaomi Mi Box automatically determines the best settings, but in rare cases requires manual adjustment in the display section. Properly exposed settings will ensure a clear picture and no black fields at the edges of the image.
Broadcasting through the built-in Chromecast feature
The simplest and most common way is to use Google Cast technology, which is built into the console operating system. Most modern Android smartphones have this feature at the system level, which allows you to display an image without installing additional software.
When choosing a broadcast device, your Xiaomi Mi Box should be displayed on the list. After pressing, the pairing process will begin, and the smartphone screen will be duplicated on the TV. This method is ideal for watching videos from YouTube, Netflix or showing presentations, since the load falls on the console, and the phone acts only as a remote control.
💡
If the broadcast icon doesn’t appear, make sure that geolocation and Bluetooth are enabled on the phone, as these are used to initially detect devices on the network.
Importantly, when using Chromecast, some applications can block the display of protected content (DRM) on the external screen, showing only a black background with sound. This is normal behavior of licensed services, and it cannot be circumvented by standard means.
Use of the wireless display function (Miracast)
Miracast is the best choice for full screen cloning, including phone menus and games. In the Android TV interface, this feature is often called Wireless Display or Translation. Unlike Chromecast, it streams live video streaming, which can create a small but noticeable delay in management.
To activate the signal reception mode on Xiaomi, you need to go to the settings and find the corresponding section. On some versions of the firmware, it is hidden in the application menu or requires activation through the developer settings. Once you turn on the standby mode, the phone will begin to search for available displays.
☑️ Checking before connecting Miracast
On Xiaomi smartphones, this feature is called “Translation” or “Wireless Monitor” in the notification curtain. On Samsung devices, it may be called Smart View, and on other brands, Screen Mirroring. Once you select the console, you will start mirroring, allowing you to control the phone lying in your pocket directly from the sofa.
Configure DLNA for Multimedia Files
If your goal is to play back video files stored in your phone’s memory, DLNA is the most efficient solution: it doesn’t broadcast the entire screen, but only the media stream, which saves battery life and ensures maximum picture quality, and for this, the Xiaomi Mi Box should have a media player that supports the network, such as a VLC or an embedded video player.
When you run a player app on your TV, go to the sources section and select Local Network or Neighborhood. Your phone should be visible as a media server. If it doesn't show up, you may need to install a media server app on your smartphone that will make files available to the network.
| Protocol | Delay. | Quality. | Battery charge |
|---|---|---|---|
| Chromecast | Low. | High (up to 4K) | Economical |
| Miracast | Medium | Depends on the network. | High-end spending |
| DLNA | Absent. | Original file | Minimum |
The advantage of DLNA is that it supports subtitles and various audio formats that may not play when you live stream the screen.You can safely use the phone for calls or other tasks while the video is played on the TV via the Xiaomi set-top box.
Broadcast from iPhone and iPad (AirPlay)
Apple owners may be faced with the question of how to bring an image from iOS to Android. Fortunately, the Xiaomi Mi Box ecosystem supports the AirPlay 2 protocol either through built-in features or through intermediary applications, which allows you to stream photos, videos and the entire screen of the iPhone without buying an expensive Apple TV.
To get started, make sure the console has an AirScreen app or similar if the built-in support is not active. Once you start the app on your TV, open Control Point on your iPhone and click Screen Replay. Your Mi Box will appear in the device list.
⚠️ Note: When broadcasting from the iPhone in horizontal mode, black stripes on the sides may occur if aspect ratio_ The video doesn't match the resolution of the TV, and that's solved by zooming in the receiver app on the console.
AirPlay transmissions are usually very high, with minimal image compression. However, a very good Wi-Fi signal is required to work reliably, because the protocol is sensitive to interference. If the image twitches, try to get closer to the router or switch to the 5 GHz band.
Solution: lags, black screen and cliffs
Even with the right setup, users can face technical problems, most often due to overloading of the Wi-Fi channel with neighbouring routers or physical obstacles. If the image on the Xiaomi Mi Box crumbles into pixels or freezes, try restarting the router and disabling other devices consuming traffic.
A black screen when playing video often indicates a problem with codecs or access rights, in such cases, it helps to clean the cache of the application through which the broadcast is being transmitted, or update the codecs in the player, and it is worth checking whether the phone is not on power saving mode, which can limit the operation of the Wi-Fi module.
The Secret to Stability
In some cases, resetting the network settings on both devices helps, remove the Wi-Fi network from the phone's memory and consoles, then reconnect by entering your password. IP-Addresses and resolves addressing conflicts in the local network.
💡
Connection stability is more important than maximum speed: 25 Mbps is enough for 4K broadcasting, but ping should be minimal, and packet losses should be zero.
