Buying a modern set-top box is only the first step towards creating the perfect home theater. Xiaomi Mi TV Box S (second generation) is based on the Android TV operating system, which provides huge capabilities but requires a competent initial configuration. Without the right setup, the user may face desynchronization of sound, poor interface performance or the inability to play certain video file formats.
In this article, we will take a look at the whole process, from initial on-line to deep technical optimization, and learn how to circumvent regional constraints, adjust audio transmission through external acoustics, and turn a console into a powerful media center. The correct configuration is able to extend the life of the device and ensure stable operation even with heavy loads. 4K-file.
It's worth noting that the Android TV interface is updated periodically, changing the location of some menu items, but the basic principles of the file system and network protocols remain unchanged. We'll look at the current 2026 customization methods, eliminating the broken ways. Get ready to turn your regular TV into a smart entertainment center.
Primary activation and configuration of the interface
The process of familiarizing yourself with the device begins immediately after connecting HDMI cables and power. When you first turn on, the system will suggest choosing a language and connecting to a Wi-Fi network. Here, it is important to choose a 5 GHz network if the router supports dual-band mode, this will provide the necessary bandwidth for streaming high-resolution video without buffering.
This is a mandatory step to access the Google Play Store, and if you don't have an account, you can create it in advance on your smartphone so you don't have to enter a password from the remote, and then the system will prompt you to update the software once you log in.
⚠️ Warning: Don't miss the upgrade phase when you first start up. New security patches and codecs are often critical to the stability of the video decoder.
Android TV is built on a horizontal series of recommendations. For comfortable use, it is recommended to immediately disable unnecessary notifications and personalization of advertising in the privacy settings. This will not only speed up the interface, but also preserve your privacy. It is also worth checking the keyboard layout if you plan to connect a physical keyboard or mouse.
Application management and installation of third-party software
The official Google Play store contains many applications, but not all of them are optimized for remote control. To install programs that are not in the store, you need to activate the developer mode. Go to Settings → About TV → Build and click on “Assembly” seven times in a row before the activation message appears.
After that, a new section "Developers" will appear in the settings menu. USB" (ADB Debugging) and "Installation from unknown sources." This will allow you to install APK-files directly from the flash drive or through the network.
- 📦 File Commander is the best file manager for navigating internal memory and USB-accumulator.
- 🌐 Send Files to TV — utility for fast wireless transmission APK-smartphone files.
- 🎬 VLC For Android – a universal player that reproduces almost all existing codecs and container formats.
When installing third-party launchers (shells), be careful. Replacing the standard interface can cause voice search or home buttons to work unstable. If you decide to change the shell, make sure it has an Android TV version, not a tablet version.
How to remove system applications?
Optimizing video and sound playback
Picture and sound quality are the main parameters for a media player. → The device → Preferences → Screen and sound should be manually issued permission 3840x2160 and refresh rate of 60 Hz (or 50 Hz for PAL-regions, even if there is a mode "Auto", this will eliminate the jerks when switching sources.
If your TV supports HDR10 or Dolby Vision, make sure that the format is chosen in the Xiaomi settings. For older TVs without HDR, it is better to force SDR to avoid looking faded or overly saturated.
| Parameter | Recommended value | Commentary |
|---|---|---|
| Permission | 4K 60Hz | Maximum clarity of image |
| Color format | RGB 8-bit / YCbCr 4:4:4 | For the best color rendering of the text |
| Dynamic range | Auto (or HDR) | Depends on TV support |
| Sound exit | Pass-through | For external receivers |
In the audio section for home theater owners, it is critical to set up a digital output, select Digital Output and set the Pass-through value, allowing an external receiver or soundbar to decode the Dolby Digital Plus and DTS formats on its own, providing full surround sound.
💡
Use an HDMI cable labeled "High Speed" or "Ultra High Speed." Cheap cables can keep the 4K HDR signal out over long distances, causing interference or a black screen.
Working with network storage and NAS
Built-in tools may not be enough to view heavy content stored on a network storage (NAS) or computer, but it is recommended to use specialized players such as Kodi or Nova Video Player, who are able to correctly display movie covers, download metadata and build a library.
The current version of Android (starting with version 11) has SMBv2/v3 enabled by default, whereas older NAS can only work on SMBv1. If the folder is not visible, check your storage security settings.
- 📁 Create a separate account on NAS Read-only rights for media content.
- 🔒 Use static. IP-Address for the console so that the paths to the files do not change after the router restarts.
- ⚡ For files over 20 GB, use a wired connection via USB-LAN Adapter as Wi-Fi may not be able to handle bitrate.
⚠️ Note: When connecting network drives, avoid using ports USB 3.0 for hard drives without power. The console port may not produce enough current, which will damage the disk file system.
If you use Kodi, set up the memory cache. By default, it may be too small for you to use. 4K-High bitrate video. Increase buffer in configuration file advancedsettings.xml It can also be used even in an unstable network.
☑️ Checking the network connection
Advanced settings through ADB
Advanced users can access system settings via the Android debugging bridge (ADB), which allows you to change hidden settings that are not available through the standard menu, and you can use the Remote ADB Shell app directly on the console or connect it to your computer to connect to it.
One useful command is to change the density of the interface (DPI), which can be useful if you use a set-top box with a projector or a monitor with a non-standard resolution, and through ADB you can turn off unnecessary system services, freeing up RAM.
adb shell wm density 240Executing this command will change the scale of the interface. The standard value is usually about 320 dpi. Reducing the value will make the interface elements smaller, allowing more content to fit on the screen.
💡
Using ADB gives you complete control over the system, but it requires caution. Changing system files can lead to the need for a full reset.
Frequent problems and their solution
During operation, users may experience overheating of the device. Xiaomi Mi TV Box S has passive cooling, so placing in a closed niche of the nightstand can lead to trottling (reduced performance) and departures of applications.
Another common problem is desynchronizing audio and video, often by switching the audio output from Automatic to Always PCM settings or vice versa, depending on how your TV is capable, and switching frame rates in the display settings also helps.
- 🔄 Reset the settings. HDMI: Turn off and turn on the cable while the device is on.
- 🧹 Clean the app cache regularly through the Storage menu".
- 🔌 Use the original power supply, as a lack of voltage causes unstable operation of the Wi-Fi module.
