Xiaomi’s current Android TVs offer users a wide range of multimedia capabilities. One of the most popular features is the ability to stream a smartphone or tablet image to a large screen without wires. This technology, known as Miracast, is embedded in most models’ software, but its location on the menu may not be obvious to beginners. Users often search for a separate app or button, unaware that the system uses different names for this feature.
In this article, we will look at exactly where the wireless display is hidden in different versions of firmware. You will learn how to prepare devices for pairing, what system requirements you need to meet and what to do if standard search does not produce results. Wireless image transmission is becoming a key element of the home theater, allowing you to show photos, videos and presentations in high resolution.
It is worth noting that the interface of TVs may vary slightly depending on the year of the model and the version of MIUI for TV. However, the general principles of the protocol remain unchanged. We will consider both standard methods of activation through the signal source menu, and more advanced methods through the system settings. Understanding these nuances will help you avoid typical errors when you first start the function.
What is Miracast and how does it work on Xiaomi TV?
Miracast is a standard for wirelessly transferring multimedia content between devices. Unlike Chromecast, which requires the use of applications that support this technology or the Chrome browser, Miracast works at the system level, broadcasting an exact copy of what is happening on the screen of your smartphone. On Xiaomi TVs, this feature is often implemented through the Wi-Fi Direct protocol, which allows you to create a direct connection between the gadget and the TV without having to connect to a single Wi-Fi network, although having a router can simplify the detection process.
It’s important to understand that in different markets and different versions of firmware, this feature can be called differently. In global versions of Android TV, it is often integrated into the “Translation” or “Cast” function, while the Chinese versions of PatchWall firmware use the term “Wireless Display” or “Wireless Display.” The data protocol provides low latency, which makes it possible not only to watch videos, but also to launch mobile games on the big screen.
⚠️ Note: When using Miracast, the smartphone and TV create a direct connection, which can temporarily reduce the Internet speed on the connected mobile device if it switches to using Wi-Fi Direct channel.
For the technology to work, both devices must support Wi-Fi Direct. Current Xiaomi Mi TVs and Redmi TVs have a built-in module that does not require the purchase of additional adapters. Image quality depends on the power of the TV's Wi-Fi module and the distance between devices. In ideal conditions, video can be transmitted in 1080p and even 4K resolution, but high bitrate requires a very stable signal.
Technical details of the protocol
Search function in the signal source menu
The fastest way to find and activate the signal reception mode on a Xiaomi TV is to use a remote control. On most models, regardless of the version of the operating system, there is a dedicated button or menu to select the source of the video signal. By clicking on the button with the login icon (often designated as an arrow square or Input), you will see a list of available HDMI ports and embedded applications.
You need to find a item on this list that might be called Wireless Display, Wireless Display, Miracast or Translation, depending on the regional version of the firmware. For example, on TVs destined for the Chinese market, this item is often at the bottom of the list or allocated to a separate category of applications. Once you select this item, the TV will go into standby mode, displaying a message on the screen that the device is ready for connection.
- 📺 Find the “Input” or “Input” button on the remote control.
- 🔍 In the menu that opens, scroll through the list to the end in search of wireless options.
- 📡 Select “Wireless Display” or “Wireless Display” to activate the mode.
- 📱 Make sure there is a connection waiting window on the TV screen.
If you don't see that item in the main login menu, it may be hidden in the Apps folder on the Android TV home screen. Look for an icon called Wireless Display. In some cases, the system may require permission to access the network on its first run, which must be verified. This is the standard security procedure for the Android operating system.
💡
If you use the broadcast feature frequently, add the Wireless Display app to your favorite on the Android TV home screen to run it with a single click.
Activation through the system settings of the TV
The second method of search is relevant for those cases when fast access through the login menu does not work or the function is disabled in the depth of the system. On Xiaomi TVs with Android TV shell, wireless settings are often integrated into the general network configuration menu. To access them, you need to go to the settings section using the gear in the upper right corner of the main screen or the menu button on the remote.
Inside the settings menu, you're interested in the network connection section, which can be called Network & Internet, Connections, or just Network. Inside this section, you should look for Screen or Translation. There's a switch that activates the visibility of the TV to external devices. Without this switch, your smartphone simply won't be able to "see" your TV in the list of available devices for Miracast.
In newer versions of MIUI for TV firmware, the path could be: Settings → Preferences → Screen → Broadcast. In this menu, you can not only enable the feature, but also configure the name of the device that will appear on your smartphone when you search, and you can also have the option to require confirmation of connection, which increases the security of your home networks.
☑️ Checking system settings
Note that some upgrades may rebrand the feature as Google Cast or integrate with Google Home services. If you don’t find the classic Miracast, try looking for options related to Chromecast built-in, as modern smartphones often use this standard as a higher priority.
Instructions for connecting a smartphone to a TV
Once you have found and activated a feature on your TV, you need to pair with your smartphone. The process may vary depending on the manufacturer of your mobile device, as menu names in Android and iOS vary. The basic requirement is that both devices should be in the zone of confident reception of Wi-Fi signal, and ideally be connected to the same network, although for Wi-Fi Direct this is not always strictly necessary, but desirable for stability.
On Xiaomi smartphones (MIUI shell), the feature is called Translation, and you can find it by opening the notification curtain and selecting the appropriate icon, or through the Settings menu → Connection and Sharing → Broadcast. Once you turn on the search, the phone will start scanning the space. When your Xiaomi TV name appears on the list, click on it to start the connection.
For devices of other brands, the names may be as follows:
- 📱 Samsung: Smart View feature in notification curtain.
- 📱 Huawei/Honor: The "Projection" or "Wireless Projection" function».
- 📱 OnePlus: Translation or Screencast».
- 📱 iPhone: AirPlay feature if the TV supports AirPlay 2.
When you connect, you may see a request for permission on your TV screen, use the remote to select "Allow" or "Accept." Then the image from your smartphone should appear on the big screen. If you see a delay or artifacts, try to move the router closer or reduce the distance between your phone and your TV, and the stability of the connection depends on the quality of the radio channel.
⚠️ Warning: When connected via Miracast, the smartphone screen will burn constantly, which can lead to accelerated battery discharge and device heating.
💡
Successful connectivity depends not only on the correct settings, but also on the absence of interference in the 2.4 GHz Wi-Fi band, which is often overloaded with neighboring routers.
Use of the built-in Chromecast app
Because Xiaomi TVs are powered by Android TVs, they have built-in support for Google Chromecast technology.This is an alternative and often more convenient way to stream content that doesn’t require finding a separate Miracast menu, in which case you’re not streaming the entire screen of your smartphone, but a specific video or photo from the app, saving battery life and providing better picture quality.
To use this method, make sure that the TV and smartphone are connected to the same Wi-Fi network. Open the application from which you want to show the content (for example, YouTube, Netflix, Google Photos or Chrome browser). Find the broadcast icon (rectangle with waves in the corner).
The advantage of this method is that the TV takes over decoding the video stream directly from the Internet, unloading the smartphone. You can turn the app down or even turn off the phone screen, and the playback on the TV will not be interrupted. This is especially convenient when watching long movies or listening to music. However, this method requires an active Internet connection at the TV itself.
If the built-in Chromecast doesn't work, you may need to upgrade your Google Cast Receiver service. You can do this through the Google Play Store on the TV itself. Find the Chromecast built-in or Google Cast app and check for updates. The current version of the software ensures compatibility with new versions of mobile apps.
Comparison of translation methods and problem solving
Users are often confused about the many options available: Miracast, Chromecast, DLNA, AirPlay. To understand which method is best to use in your situation, consider the comparative table of characteristics relevant to Xiaomi TVs.
| Characteristics | Miracast (Wi-Fi Direct) | Chromecast built-in | DLNA |
|---|---|---|---|
| Type of transmission | Screen cloning | Streaming | Translation of files |
| Dependence on the phone | High (screen should be on) | Low (can be rolled) | Low. |
| Network requirement | Not necessarily (Direct) | Definitely (uniform Wi-Fi) | Definitely (uniform Wi-Fi) |
| Video quality | Depends on the power of the phone. | Maximum (decodes TV) | Original |
If you encounter connectivity issues, the first step should be to reboot both devices.Often temporary disruptions to Xiaomi's network modules TV It is possible to simply turn off the TV from the outlet on 10-15 It's also worth checking if the router is insulating customers (AP Isolation, which prevents devices on the local network from seeing each other.
Another common problem is codec incompatibility or an outdated version of Wi-Fi drivers on a smartphone, in which case resetting network settings on a mobile device can help. On a TV, you can try to remove the device from the trusted list (if such an option is available in the Bluetooth menu and devices) and perform pairing again. Hardware reset TV should only be used as a last resort if other methods do not help.
