Today’s users rarely use built-in apps on their TVs, preferring to stream content directly from their smartphones. Xiaomi Mi TV 4S features a powerful Android TV operating system that makes it easy to display images from their mobile device to the big screen, giving them access to thousands of movies, games and photos that are more convenient to watch in high resolution.
The setup process may seem complicated at first glance, but it actually takes only a few minutes. You don't need additional cables or complex adapters, because everything works over a wireless Wi-Fi network. The main thing is to understand the difference between the data protocols that your particular TV model supports.
In this article, we will look at all the available methods of connection, from standard system functions to specialized applications. We will also look at the typical errors that occur when syncing devices and how to quickly fix them. Careful follow the instructions will help you enjoy multimedia content without technical problems.
Preparation of equipment and Wi-Fi network
The foundation of stable wireless data is a quality network. Before you try to connect your smartphone and TV, make sure that both devices are connected to the same access point. If you have a dual-band router, you better use a 5 GHz network, as it provides higher bandwidth for video streaming.
A common mistake is connecting your phone to 4G/5G mobile internet while your TV is running over Wi-Fi, which is impossible to detect, and it’s also worth checking if the router is running customer isolation mode, which prevents devices from seeing each other.
⚠️ Note: If your router gives away two networks with the same name (2.4 GHz and 5 GHz), some older smartphones may not see the TV.
Make sure both devices are updated to the latest version. On the Xiaomi Mi TV 4S, you can check this in Settings → About TV → System Update. On a smartphone, updates usually come via Google Play or the App Store. Older versions of firmware may contain bugs that block Miracast protocol.
💡
Use the Wi-Fi Analyzer app on your phone to check for channels loading. If the channel is congested by neighbors, switch the router to a free channel to improve broadcast stability.
Use of the built-in Chromecast feature
Since the Xiaomi Mi TV 4S runs on Android TV, the most native and convenient feature is the built-in Chromecast.This protocol is developed by Google and allows you to transfer content from supported applications with one touch. You do not need to duplicate the entire screen of the phone, which saves battery life.
To get started, open an app you want to show content from, like YouTube, Netflix, or VK Video. Find the broadcast icon, which is a rectangle with waves in the corner. After you click, the system will prompt you to select a device. Your Mi TV 4S should appear in the list.
- 📱 Make sure the app supports Cast (usually popular streaming services).
- 📡 Check that the phone and TV are in the same subnet (the same). IP-router).
- 🔋 Close the background apps on your phone to free up resources to code the flow.
If the stream icon doesn't appear, Google Play services on your TV may need an update. Go to the Google Play Store on your TV, go to your profile and select App and Device Management.
Screen broadcast via Miracast (Wireless Monitor)
When you want to bring to the big screen exactly what is happening on the display of the phone, including menus and games, Miracast technology is used. On Xiaomi TVs, this feature is often called “Wireless Monitor” or “Wireless Display.” Unlike the Chromecast, it does full mirroring.
To activate the mode on the Xiaomi Mi TV 4S, go to the app menu and find the Wireless Monitor shortcut. If it is not on the home screen, it can hide in the My Apps folder or in the Tools section. After you run, you will see a wait for the connection on the screen.
On Android smartphones, the path to function may differ depending on the manufacturer’s shell:
- 📲 Xiaomi (MIUI): Control panel → Broadcasting.
- 📲 Samsung: Curtain panel → Smart View.
- 📲 Huawei/Honor: Control panel → projection.
After you search for your devices, select your TV from the list. You may see a request for permission to connect on your TV screen — confirm it with the remote control; the image from the phone will appear on the full screen. It is important to understand that when you use Miracast, the phone does not go out, but continues to work in active mode.
☑️ Checklist of successful Miracast connection
Connecting Apple devices (iOS) to Xiaomi TV
iPhone and iPad owners often face difficulties, as Apple’s ecosystem uses the AirPlay protocol, which is not native to Android TV. However, the Xiaomi Mi TV 4S model has built-in support for AirPlay 2 or is compatible with it through system services, which allows you to stream videos and photos without installing additional software.
To turn on the stream, open Control Point on your iPhone (swipe down from the top right corner or bottom up on older models). Click Screen Replay (two rectangles). Select your TV from the list. If the TV requires a code, it will show up on the screen and you will need to type it into your iPhone.
⚠️ Attention: For stable operation of AirPlay on Xiaomi Mi TV 4S Sometimes you need to activate the appropriate module in the settings of the TV. → General. → Apple AirPlay and convince!
The image quality is usually higher when using AirPlay than with standard Miracast, thanks to the optimization of Apple codecs. However, the input lag can be noticeable, so playing dynamic shooters through this method is not recommended.
Third-party applications for enhanced capabilities
If standard methods don't work or additional features like file transfer or computer management are required, third-party apps come to the rescue.The Google Play store on the TV offers a variety of solutions, but not all are equally useful and safe.
One of the most popular solutions is the TV Cast app or Web Video Caster, which allows you to send video files directly from your phone's browser to your TV without having to download to your TV device itself, which is especially true for models with a small amount of internal memory.
Also worth mentioning is Xiaomi Mi Remote, which is designed to manage, but sometimes helps connect devices in the same ecosystem. For advanced users, there are utilities like LocalCast that can work with NAS network storage.

Solving Connection and Delay Problems
Even with the right setup, users can encounter artifacts, audio desynchronization, or no image at all, most often due to congestion of the Wi-Fi channel or insufficient speed of the smartphone processor when encoding real-time video.
If the image twitches or is low resolution, try to lower the flow quality in the source application settings. Also helps is rebooting the router and clearing the cache of the Wireless Display app on your TV. To do this, go to Settings → Apps → Wireless Monitor → Clear the cache.
In some cases, the antivirus on your phone or the firewall on your router can block the ports required for DLNA or Miracast. Temporary shutdowns will help diagnose the problem. If everything works after that, add the devices to the exceptions.
💡
90% of broadcast problems are solved by restarting the router and checking that both devices are in the same frequency band (2.4 or 5 GHz).
