Xiaomi’s modern smart TVs make it possible to turn a normal media viewing experience into a full-fledged multimedia experience. The ability to duplicate the screen of a mobile device on a large diagonal opens up access to high-resolution games, movies and presentations. Users often look for ways to quickly and wirelessly transmit images from a smartphone.
There are several proven methods, each with its own features and software requirements, and the choice of the specific method depends on your TV model, the version of the Android operating system or MIUI, and the type of content being broadcast. In this article, we will discuss in detail all available synchronization options.
You don't need to buy expensive cables or adapters, because most of the features are built into the system by default, just make sure that both devices are on the same LAN, and we'll look at both the standard system tools and third-party utilities for specific tasks.
Network and device preparation requirements
A fundamental condition for successful wireless data transfer is a stable connection. Both devices must be connected to the same Wi-Fi network. If your router supports two frequency bands, make sure that both the phone and the TV work in one of them, preferably in the 5 GHz band to reduce latency.
⚠️ Note: Using a guest Wi-Fi network or customer isolation on a router can block devices from being discovered by each other, even if they are connected to the same access point.
Check the software version on both devices. Miracast and Google Cast require up-to-date security updates and system patches to work properly. Go to Settings → About TV → System Update and check for new firmware.
💡
If the broadcast is running late, try temporarily disabling other devices consuming heavy traffic, or reboot the router to clear the buffer.
It’s also worth making sure that the TV is activated, depending on the Xiaomi Mi TV or Redmi TV model, this option can be called differently, but it’s usually turned on by default when you have a network connection.
Use of the built-in function Wireless monitor
The most common method that doesn’t require additional software is based on Miracast technology, which in the Xiaomi ecosystem is often called a Wireless Monitor or a Wireless Display, which allows you to completely clone an image from your smartphone onto your TV screen.
To start the process, on the TV remote, click the signal source button, which is usually indicated by the square icon with an arrow or an Input signature. In the menu that opens, select "Wireless Monitor." The screen will display a wait for connection.
☑️ Checking Miracast's connection
Now, to the smartphone settings, open the notification curtain and find the "Translation," "Smart View" or "Wireless Monitor" icon. After scanning the network, your Xiaomi TV should appear on the list. Click on it to establish a connection.
The quality of the image in this mode depends on the power of the Wi-Fi module and the distance to the router, there may be small delays of the cursor or sound, which is normal for this protocol of compression of the video stream in real time.
Broadcasting via Google Home and Chromecast
Most modern Xiaomi TVs run on Android TV or have built-in support for Chromecast technology.This allows you to stream content from specific applications (YouTube, Netflix, Chrome browser) directly without loading the phone’s processor with full screen duplication.
Google Home is the perfect way to manage this process. Download it from the Play Market if it hasn't already been installed. Open the app and it will automatically find available devices online. Select your TV from the list.
| Parameter | Miracast | Chromecast built-in | Third-party annexes |
|---|---|---|---|
| Delay. | Medium/High | Low. | Depends on the software. |
| Battery consumption | High-pitched | Low. | Medium. |
| Sound quality | Synchronization varies | Great. | Good. |
| Working in the background | No (screen active) | Yes. | Partially. |
In the Google Home app, click the "Cast my screen" button, and the system will warn you that all actions on your phone will be visible on your TV, and confirm the action by clicking "Start now".
Application of third-party broadcasting applications
In some cases, the regular tools may not work properly because of the specifics of codecs or Android versions, and then specialized utilities come to the rescue. One of the most popular is AirScreen, available in the app store on the TV.
Install the app on your TV via the Google Play Store, and when it launches, it will prompt you to turn on the services you need (AirPlay, Google Cast, Miracast) and follow the instructions on the screen to activate the receiver.
⚠️ Note: Free versions of third-party apps may display ads on the TV screen, and removing them often requires buying premium access within the app.
For iPhones that don’t natively support Miracast, using apps like AirScreen is the only wireless way to display an image via the AirPlay protocol.This makes Xiaomi’s ecosystem compatible with Apple devices.
Another option is to use the LocalCast app or Web Video Caster, which allows you to send video files stored in your phone’s memory or stream video from your browser directly to your TV, bypassing system restrictions.
Video and photo broadcast from the gallery
If your goal is to show friends photos from your last vacation or a video shot on camera, you don't have to duplicate the entire screen.The standard MIUI gallery and Google Photos have a built-in casting feature.
Open the photo or video you want in the gallery. Find the Translation icon (the rectangle with the waves in the corner) or click Share and select your TV from the list of available DLNA/Chromecast devices.
This method is particularly useful because it allows you to control playback from your phone, pause or rewind while the TV is watching video, and you can use the phone for other tasks without interrupting the display.
Why can't the video be played?
This is also ideal for viewing presentations or documents, and it will scale to the resolution of the TV array, providing a clear picture without black bars at the edges.
Troubleshooting and troubleshooting
Even if you follow all the instructions, there may be technical failures. If the TV is not visible in the list of available devices, the first thing you do is check the firewall settings on the router. Sometimes the antivirus software on the phone blocks local connections.
Try resetting network settings on both devices. On the TV, you can do this through the Settings menu → Network → Reset. On the phone, select Network Resets in the System Settings section. This will not delete your data, but update the connection configuration.
⚠️ Note: If after resetting the network settings, the TV stopped connecting to the Internet, you will need to re-enter the password from Wi-Fi using the virtual keyboard on the remote control.
A common problem is desynchronization of sound and image, which is treated by changing the buffering in the settings of the translation application or by reducing the quality of the stream in the settings menu of the wireless display.
💡
Rebooting the router solves 80% of device detection problems on the local network, as it updates DHCP-leases and the ARP table.
If nothing helps, use a wired connection via a USB-C to HDMI adapter.This is guaranteed to give a stable picture without delay, although it will deprive you of the convenience of wireless control.
