Modern multimedia systems demand flexibility, and the ability to instantly stream content from a mobile device to a large screen has become a quality standard. TV owners Xiaomi Mi TV 4S People often look for ways to eliminate unnecessary wires by harnessing the power of built-in Wi-Fi to transmit video, photos, and audio. This isn't just convenient for browsing family archives, but also essential for presentations or gaming on a large display.
The process of synchronizing gadgets into a single ecosystem may seem complicated due to the variety of operating systems and data transfer protocols. However, if you understand the basic principles of operation Miracast And DLNAThe procedure will only take a couple of minutes. In this article, we'll cover in detail all available methods applicable to the latest Android TV firmware versions.
It's worth noting that connection stability directly depends on the quality of your home network. Before setting up, make sure your router supports 802.11n or higher and that the signal in the room you're receiving is strong. Any interference can cause image desync or audio lag.
Preparatory stage and network requirements
The foundation of successful wireless streaming is a properly configured local network. The first and most important rule: your smartphone and TV. Xiaomi Mi TV 4S must be connected to the same Wi-Fi network. If you have a dual-band router, it's recommended to use the 5 GHz band for transmitting heavy high-definition video streams.
Check your router settings, as some models isolate client devices from each other by default for security purposes. This feature is often called AP Isolation or "Access Point Isolation." If enabled, devices simply won't "see" the TV in the list of available devices for casting.
⚠️ Note: If you're using a guest Wi-Fi network on your router, streaming may not work due to local resource access restrictions. Switch both devices to the main network.
Also, make sure your TV has the latest software version. Manufacturers regularly release updates that improve the stability of wireless protocols. To check, go to the settings menu and select Settings → About TV → System Update.
Using Chromecast Built-in
The Android TV operating system that powers it Xiaomi Mi TV 4S, has built-in support for Google Chromecast technology. This is the easiest and most reliable way to stream content, especially if you use Google services or apps that support this feature.

Google Home or the corresponding media apps (YouTube, Netflix, Twitch). Open the app on your phone and look for the broadcast icon—a rectangle with waves in the corner.
After clicking the icon, the system will prompt you to select a target device. Your device should appear in the list. Xiaomi TVClick it, and the content will begin playing on the big screen. In this case, control is performed using your phone, which acts as a remote control.
- 📱 Make sure Bluetooth is enabled on your smartphone for initial device detection.
- 🌐 Both devices must be in the same subnet (same gateway IP address).
- ▶️ For YouTube, simply click the broadcast button inside the video itself.
- 🔒 When you connect for the first time, a confirmation code may appear on the TV screen.
Screencasting via Miracast (Wireless Display)
If your goal is to display exactly what is happening on the smartphone display (desktop, browser, games), you will need technology MiracastOn TV Xiaomi This feature may be called "Wireless Display" or "Screen Mirroring".
To activate the mode on your TV, go to the main menu and find the application Wireless Display or similar. Once launched, a connection screen will appear. On an Android smartphone, go to Settings, select "Connection and Sharing" (or "Cast"), and enable the feature.
Apple devices (iPhone, iPad) use the AirPlay protocol, which is also supported by many models XiaomiIn this case, open Control Center on iOS, tap "Screen Mirroring," and select your TV from the list. Picture quality with this method depends on the phone's processor power and Wi-Fi speed.
| Parameter | Android (Miracast) | iOS (AirPlay) | Chromecast |
|---|---|---|---|
| Delay | Average | Low | Minimum |
| Quality | Depends on the signal | High | Adaptive |
| Phone battery | It is consumed quickly | It is consumed quickly | It saves money |
| Game support | Yes | Yes | Only in apps |
☑️ Check before screencasting
Third-party apps for advanced features
Built-in tools don't always provide the desired functionality, especially when transferring files of specific formats or enabling remote control. In such cases, specialized apps available in the store come to the rescue. Google Play Store on the TV itself.
One of the most popular solutions is the application Xiaomi Mi Remote or universal analogs like TV CastThey not only allow you to mirror your screen but also transfer files directly to your TV's memory. Installation is done by searching for apps on your TV or downloading an APK file.
After installing the app on your TV, you need to install a similar program on your smartphone. Syncing usually happens automatically if the devices are on the same network. Simply select a file or the "Screen Cast" function in the app interface.
⚠️ Note: Some free versions of apps may display full-screen ads or have session time limits. Please read the terms of use carefully before installing.
For advanced users, there are tools like AirScreen, which emulate AirPlay and Chromecast receivers at the software level, increasing compatibility with older or non-standard devices. This can be a lifesaver if standard protocols are unstable.
Should I install DLNA client apps on my TV?
Installing a DLNA server on your phone and a client on your TV (or vice versa) is a great way to view large files without compression. However, for simple YouTube streaming, this is overkill, as the TV will automatically download the video from the internet.
Solving common connection problems
Even if you follow all the instructions, technical issues may still occur. Most often, the problem lies in the network service cache or temporary DNS errors. If the TV stops detecting your phone, try a full reboot: unplug both devices from the power outlet for 30 seconds, then plug them back in.
Another common cause is using a VPN on your smartphone. When a virtual tunnel is enabled, the phone accesses the global network through a different IP address and "doesn't see" local devices. Be sure to disable any VPN services before attempting to connect.
If the image is choppy or intermittent, reduce the stream quality in the app settings or move the router closer to the TV. Wireless transmission protocols are very sensitive to data packet loss.

Settings → Network. - 📡 Check if your Wi-Fi channel is overloaded by neighboring routers.
- 📱 Update the app you are using to broadcast.
- 🔌 Try connecting your phone to a different access point (for example, sharing Wi-Fi from another phone) for diagnostics.
Comparison of wired and wireless connections
Despite the popularity of Wi-Fi, sometimes a wireless connection can't provide the necessary stability, especially for 4K gaming or VR content. In such cases, it's worth considering alternatives, although this article focuses specifically on wireless methods.
Wired connection via adapter USB-C to HDMI Guarantees zero lag and maximum picture quality. However, this reduces mobility and requires additional accessories. Wireless offers convenience but sacrifices absolute signal reliability.
The choice of method depends on your priorities. Wi-Fi is ideal for viewing photos, YouTube, or presentations. For eSports gaming or professional video editing, a cable or specialized gaming streaming devices are better.
Is it possible to connect a phone to a Xiaomi TV 4S without Wi-Fi?
Yes, this is possible using an HDMI cable and the appropriate adapter for your smartphone (USB-C to HDMI or Lightning to HDMI). Some models also support USB connection, but only for media playback, not screen mirroring.
Why is there only sound but no image?
Most often, this is a codec or content format issue. Make sure the source app supports video output. Also, try changing the screen resolution in your phone settings or updating the app on your TV.
Does broadcasting affect internet speed?
Yes, when using Chromecast or DLNA, traffic goes through the router but doesn't load the smartphone's bandwidth. When mirroring your screen (Miracast), traffic goes directly between devices (Wi-Fi Direct), saving internet bandwidth but loading up the Wi-Fi airtime.
How to improve picture quality during wireless broadcasting?
Use a router that supports 5 GHz, place it within direct line of sight of the TV, and close background apps on your smartphone that consume data.
