Modern smart home ecosystems require seamless integration of devices, and pairing an Android smartphone with a Xiaomi TV is one of the most popular configurations. Users often look for ways to display images from their mobile screen on a large panel to watch movies, show photos or run mobile games in high definition. Technology Miracast, built into the MIUI TV shell, allows you to implement this task without the use of additional adapters, ensuring stable transmission of the video stream.
However, the synchronization process does not always go smoothly the first time due to differences in firmware versions or router settings. In this material we will analyze in detail all available connection methods: from the standard “Broadcast” function to the use of third-party utilities and cable connections. You will learn how to set up Wi-Fi Direct, what hidden settings you may need and how to eliminate common connection errors.
Preparing equipment and network
Before starting setup, make sure that both devices - your smartphone and TV Xiaomi Mi TV - are connected to the same wireless network. This is a fundamental requirement for the operation of most wireless data protocols. If your router supports dual-band, it is recommended to use network 5 GHzas it provides the higher bandwidth needed to stream 4K video without lag.
Check that the software on both gadgets is up to date. Outdated Wi-Fi module drivers may cause connection interruptions or inability of devices to be detected by each other. On the TV, go to menu Settings → About TV → System update and install the available packages. A similar procedure should be carried out on the phone in the system updates section.
⚠️ Attention: If your router isolates client devices (AP Isolation function), the TV and phone will not see each other even on the same network. Disable this option in the router settings.
You should also make sure that the signal reception mode is activated on the TV. In the interface PatchWall or the standard Android TV shell, this function may be called differently, but it is usually available through the quick access panel or the main application menu.
Standard broadcast via the built-in function
The easiest way to mirror the screen is to use the native Android function, which is often called “Cast”, “Smart View” or “Wireless projector” depending on the smartphone manufacturer. The TV interface Xiaomi automatically scans the broadcast for requests from mobile devices if the corresponding service is running.
Open the quick settings panel on your phone by swiping from top to bottom and find the broadcast icon. After clicking, the system will begin searching for available receivers. When the name of your TV appears in the list (for example, MI TV 4S 55), select it to initiate the connection.
- 📱 Make sure that the phone screen is unlocked while searching for a device.
- 📺 A request to confirm the connection may appear on the TV - accept it with the remote control.
- 🔄 If the connection is not established, try restarting the Wi-Fi module on both devices.
After successful pairing, the image from the mobile display will appear on the TV screen in real time. It is worth considering that this method uses a protocol Miracast, which duplicates the entire screen, including notifications and the navigation bar. To watch the video in landscape orientation, simply rotate the phone.
Using the Google Home application
If the standard function of your smartphone does not see the TV or is unstable, the official application Google Homewill be an excellent solution. It uses the Chromecast built-inprotocol, which is supported by most modern Xiaomi models based on Android TV. This method often provides a more stable picture and allows you to stream content from specific applications, rather than the entire screen.
Install the application from the store Google Play and sign in to your account. The app will automatically scan the local network and display available smart home control devices, including your TV. Click on the TV icon in the list of devices to open the control panel.
At the bottom of the interface you will find the “Cast Screen” button. Clicking on it will start the process of capturing an image and sending it to a large panel. Unlike Miracast, here the latency may be slightly higher, but compatibility with various applications is much wider.
To save battery power during a long broadcast, connect the phone to a charger, since transmitting the video stream heavily loads the processor and Wi-Fi module.
⚠️ Attention: Some applications (for example, Netflix or banking services) may block screen casting for security or copyright reasons (DRM). In such cases, the image will be black, although the sound can be transmitted.
Broadcasting video from specific applications
Many popular video services have a built-in casts button, which allows you to send a video stream directly to your TV without duplicating the entire smartphone screen. This frees up your mobile device for other tasks and saves energy, since video decoding is done by the TV's processor.
Open an application, for example, YouTube, and look for the rectangle with waves icon in the corner of the video player. When clicked, a list of devices will appear. Select your Xiaomi TVand the video will start playing on the big screen, and the phone can be used as a remote control.
| Application | Broadcast type | Features |
|---|---|---|
| YouTube | Chromecast | Supports 4K HDR, the phone works like remote control |
| Netflix | Chromecast | Requires DRM support on TV |
| VLC Player | DLNA / Cast | Playing local files from the phone |
| Google Photos | Chromecast | Demonstrating a slide show from an album |
This method is especially convenient if you want to show a presentation or a photo album to friends, without being distracted by instant messenger notifications that inevitably pop up when the screen is completely duplicated. The picture quality when broadcasting live from an application is often higher than with screen mirroring.
Wired connection via USB-C to HDMI
For users who are critically important to minimal signal latency (for example, gamers) or connection stability regardless of the quality of Wi-Fi, there is a wired option. It requires a port on your smartphone. USB Type-C with standard support MHL or DisplayPort Alt Mode on your smartphone.
You will need a special adapter or USB-C to HDMI cable. One end connects to the phone, the other to a free port HDMI on the back of the TV. After connection, the TV will automatically detect the new signal source and switch to it.
☑️ Checking cable compatibility
Not all smartphones support video output via USB. Budget models often have USB 2.0 ports, which are intended only for charging and data transfer, but not video signals. Before purchasing an adapter, be sure to check the specifications of your phone model on the manufacturer's official website.
⚠️ Attention: When using long, low-quality cables, artifacts may appear in the image or periodic signal loss. Use certified cables up to 2 meters long.
Solving problems with connection and delays
If you are faced with the fact that the TV does not see the phone or the connection is constantly disconnected, the problem most often lies in the network settings. Try forgetting the Wi-Fi network on both devices and reconnecting by entering the password. Sometimes changing the router's broadcast channel to a less busy one helps.
A high delay (lag) between the action on the phone and the display on the screen is typical for wireless methods. This is due to the time it takes to encode and decode the video stream. To reduce lag, close background applications on your smartphone that consume traffic or processor resources.
In rare cases, you may need to reset the network settings on your TV. Go to Settings → Network and Internet and select reset network settings. This will delete saved Wi-Fi passwords, but may resolve software conflicts of the communication module.
What to do if there is sound but no picture?
This is a common problem when resolutions are incompatible. Go to your phone's settings, "Screen" section, and try manually changing the resolution or frame rate to lower values (for example, 720p 60Hz), then try connecting again.
Frequently asked questions
Can I connect my phone to a Xiaomi TV without Wi-Fi?
Yes, this is only possible using a wired connection via a USB-C to HDMI adapter. Wireless technologies (Miracast, Chromecast) require a shared local network or a direct Wi-Fi connection between devices.
Why is the Xiaomi TV not displayed in the list of available devices?
Make sure that the “Broadcast” application or a similar signal reception service is running on the TV. Also check whether client isolation is enabled on the router and whether the devices are on the same subnet.
Does broadcasting affect the quality of the video on the phone itself?
When using Miracast, the phone simply duplicates the picture, so the quality does not change, but the interface can be rotated. When broadcasting from applications (YouTube), the phone can turn off the screen to save energy, since processing is carried out by the TV.
Does Xiaomi support audio transmission to external speakers during broadcasting?
Yes, sound is transmitted along with the video stream. If a sound system is connected to the TV via Optical or HDMI ARC, the sound will be played through it. The volume is controlled by the TV remote control.
The stability of the wireless connection is 90% dependent on the quality of the router and the absence of interference on the air, so using the 5 GHz band is a priority for comfortable viewing.
