Modern Xiaomi smartphones have powerful screens, but to view content on a large diagonal often requires broadcasting the image on the TV. This may be necessary to show photos, watch videos from unverified sources or conduct presentations. Owners of MIUI and HyperOS devices have several built-in tools to accomplish this task without installing third-party software.
The synchronization process depends on the type of TV you have and the protocols you support. If you want to bring your Xiaomi screen to your TV, the first thing you need to do is make sure that both devices are connected to the same Wi-Fi network. It's the shared LAN that is the foundation for wireless data technologies like Miracast or Google Cast.
In this guide, we’ll cover all the current techniques, from standard system features to the use of specialized applications, and you’ll learn how to set up a connection in a couple of minutes and enjoy content on the big screen.
Preparation of devices for wireless connection
Before you start setting up, it’s important to get the hardware properly prepared.Make sure your Smart TV supports Miracast technology (often called Screen Mirroring, Wi-Fi Direct or simply “Translation”).Most modern models from Samsung, LG, Sony and Philips have this feature out of the box.
On Xiaomi smartphones, the process may vary slightly depending on the shell version. In newer versions of HyperOS, the interface may have changed, but the logic remains the same. Open the notification curtain and find the Translation icon. If it's not on the visible panel, click on a pencil or three menu editing dots and add this widget.
⚠️ Warning: Make sure the TV doesn’t turn on Guest Network or customer isolation, or devices won’t see each other on the LAN.
Also check that the TV does not run heavy applications that can overload the Wi-Fi module. the stability of the connection depends on the quality of the router signal.
Use of the built-in Translation (Miracast) function
The easiest way to do this without having to install additional software is to use Miracast, which is built into the Android core and allows you to duplicate the screen with minimal latency. First, activate the search mode on your TV. On Samsung models, this is often done by choosing the source of the Screen Mirroring signal, on LG, by launching the Screen Share app.
On a Xiaomi smartphone, go to the Translation menu. The system will start searching for available devices. Once you see your TV name on the list, click on it. A request for confirmation of connection may appear on the TV screen — agree with it using the remote.
- 📱 Open "Settings» → «Connection and sharing» → «Broadcasting».
- 📺 Enable Miracast on your TV via the signal source menu.
- 🔗 Click on the name of your TV in the list on your smartphone.
- ✅ Confirm the connection on the TV screen if required.
Once paired successfully, the image from the phone mirrors itself completely onto the big screen, so you can switch apps, play games, or flip through the gallery, but you should also consider that when you're using your smartphone, the image may twitch if the Wi-Fi signal is unstable.
☑️ Checking before connection
Google Home (Chromecast built-in)
If your TV is running Android TV or has built-in support for Google Cast, it is better to use the official Google Home app.This method provides a more stable video stream and allows you to stream content from specific applications without loading the phone processor with full screen duplication.
Download the Google Home app from the Play Market if it hasn't already been installed. Open it and log in to your Google account.The app will automatically find Chromecast devices or Cast-enabled TVs on the same Wi-Fi network.
Select your TV from the device list. In the control menu that opens, click the "Cast screen" button. The system will warn you that your audio and video will be broadcast to the TV. Confirm the action.
| Method | Delay. | Quality. | Battery consumption |
|---|---|---|---|
| Miracast | Low. | High. | Medium. |
| Google Cast | Medium | Maximum. | Low. |
| HDMI cable | Absent. | Maximum. | Charging. |
Why is Google Cast Better for Video?
Broadcast via the Mi TV app (for Xiaomi TVs)
Xiaomi ecosystem owners can use the Mi TV app (or Xiaomi TV+) to provide deep integration between the smartphone and the TV, allowing not only duplicate screens, but also transfer files, use the phone as a remote control and manage the media library.
Run the app on your smartphone. It scans the network and finds compatible devices. Select your TV from the list. To start the broadcast, click on the Translation icon in the upper right corner or select Screen Translation from the menu.
The functionality of the application allows you to display photos and videos from the gallery in high resolution 4K, which is especially important for owners of TVs with HDR support. The interface is adapted for horizontal mode, which is convenient for control from the sofa.
⚠️ Attention: When using the Mi application TV Make sure that the TV also runs the appropriate app or the Mi signal reception function is enabled. Drop/Mi Share.
If the automatic search does not give results, try entering PIN-code that can be displayed on a TV screen, in the appropriate field on a smartphone, which increases security and prevents unauthorized access to your screen.
Wired connection via HDMI and USB-C
Wireless technology is convenient, but it doesn’t always provide perfect stability, especially in games. For minimal latency (input lag), it’s better to use a cable connection. However, there’s an important caveat here: not all Xiaomi smartphones support video output via a USB Type-C port.
The technology is called MHL or DisplayPort Alt Mode. If your flagship (like the Mi series or Xiaomi older models) supports video output, you'll need a USB-C to HDMI adapter. Connect the cable to your TV and phone.
Settings → Connection and Sharing → HDMIIn some cases, you need to manually switch the signal source on the TV to the appropriate HDMI 1 or HDMI 2 port. The image should appear automatically. If this does not happen, it is likely that your smartphone does not support video output through the charging port.
- 🔌 Use a high-quality adapter with support HDCP 2.2 4K content.
- 🔋 A cable connection can quickly discharge the battery if you do not use a rechargeable adapter.
- 🎮 Ideal for games where reaction is important, such as shooters or racing.
💡
Use the USB-C Hub adapter with a charging port, which will allow you to simultaneously stream the image to the TV and charge the smartphone, since the video output mode consumes a lot of power.
Broadcasting through DLNA and third-party applications
If standard methods don't work, aggregator applications like Web Video Caster or BubbleUPnP come to the rescue. They use the DLNA protocol, which is supported by almost any Smart TV, even the old one, in which case it doesn't broadcast the entire screen, but a specific file or video stream from the browser.
Install the app on your smartphone and, if required, a server app on your TV (although a built-in media player is often enough). Open a video file or website link in the caster app. Select your TV as your playback device.
This method is great for watching videos from sites that don’t have official TV apps. You can control playback, pause, and rewind directly from your phone.
⚠️ Note: When broadcasting through DLNA Some subtitles may not display correctly.We recommend using embedded subtitles or formats. SRT.
The advantage of this method is that it's versatile, and even if you don't have a Smart TV, but a regular Android console, these apps can find the device online and play it.
💡
DLNA is ideal for playing a media library, but is not suitable for games or displaying application interfaces, as it only transmits content, not a desktop image.
Troubleshooting and troubleshooting
Often, users find that the TV is not visible on the list of available devices. First of all, check whether the antivirus or firewall on the router blocks the local connection. Sometimes it helps to simply restart the router and both devices.
If there is an image but no sound, check the audio settings in Android. In broadcast mode, the sound can stay on the phone. Press the volume button and select the output to an external device or Bluetooth headset if the TV does not support an audio codec.
If you have severe delays (lags), try lowering the resolution in your phone’s settings or getting closer to the router, and closing background apps that may be consuming traffic.
