Many users of Xiaomi, Redmi and POCO smartphones often face the need to display images on the big screen, but can not find the usual “Miracast” feature in the settings. This is due to the fact that in modern versions of the MIUI and HyperOS shell, Xiaomi has abandoned the use of the term Miracast in favor of a more modern name “Translation” or “Cast”.
In fact, the technology hasn’t gone away, it’s just been renamed and integrated into system services to make it easier to work with smart homes and TVs. Screen broadcasting now works on Wi-Fi Direct protocol, which provides more stable connectivity and less latency. Understanding how Xiaomi implemented this functionality will help you quickly start sharing content with friends or watching movies on TV without unnecessary wires.
In this article, we will take a look at where to look for this feature in different versions of firmware, how to set up a connection correctly, and what to do if the phone can’t see the TV. You will learn about hidden settings that can improve image quality, and get answers to the most common questions that arise when trying to sync devices.
From Miracast to Broadcast: The Evolution of the Title in MIUI and HyperOS
Historically, the wireless media protocol was called Miracast, and in early Android versions it often appeared under that name. However, with the development of the Xiaomi ecosystem and the introduction of deep integration with Chromecast built-in, the developers decided to unify the names. Now on the settings menu you will find the terms "Translation", "Cast" or "Wireless display", which is actually the very feature you are looking for.
The change is driven not only by marketing considerations but also by technical necessity: Modern Smart TVs support many protocols, and Xiaomi is committed to ensuring compatibility with all popular standards. The renaming helps avoid confusion among users who may be looking for a feature to duplicate screens, not just stream videos from apps.
It's important to understand that not having the word "Miracast" in a search doesn't mean that it's broken or missing a feature. It's just a new interface to get used to. If you move from another Android brand, finding the right item may take a while, but the way things work is the same.
⚠️ Note: If you are using a very old version MIUI (for example, MIUI 9 or 10), the function may be called “Wireless Display” and may be located in the “Additional Features” section. MIUI 12, 13, 14 and HyperOS search for Translation».
Where to look for the translation function: step-by-step instructions
There are a number of ways to find the tool to display the image, and the method depends on your firmware version and your personal preferences in managing your smartphone. The easiest and fastest way is to use the notification curtain. Swipe from top to bottom across the screen to open the control center, and find an icon called Translation, or an icon that resembles a wave screen. If there is no icon, click on a pencil or edit button to add it to the active switches.
The second way is through the standard settings menu. The path may vary slightly depending on the model, but most often it looks like this: go to Settings → Connection and Sharing → Broadcast. In some regions or on global firmware, this item may be hidden under the Connected Devices section. Once the slider is activated, the phone will start searching for available devices on the Wi-Fi network.
The third option is for those who like voice control or are afraid of getting confused in the menu. Just call the Google Assistant or Xiao AI (if you are configured) and say the phrase "Enable the broadcast." The system will automatically open the desired settings section, which is especially convenient if you do not want to search for the feature manually.
- 📱 Through the curtain: swipe from top to bottom → Icon "Translation».
- ⚙️ Through Settings: Settings → Connection and sharing → Broadcasting.
- 🔍 Through Search: Enter “Translation” in Search by Phone Settings.
Remember that to work properly, both devices must be connected to the same Wi-Fi network, a critical condition without which the phone simply will not detect the TV or console.
Configuring the connection to the TV and consoles
Once you’ve found the feature, the next step is to connect to the signal receiver correctly. Modern Smart TVs from Samsung, LG, Sony and other manufacturers have built-in support for the protocols used by Xiaomi. When you turn on the Translation feature on your smartphone, a request for connection permission may appear on the TV screen, which must be confirmed by the remote.
If you have an old TV without a smart one TV, But if you have an Android set-top box or a Mi Box, the process will be the same. Make sure that the set-top box is on live stream standby or open-source. In some cases, you may need to manually enter. PIN-code that will be displayed on the TV screen to ensure connection security.
It is worth noting that the quality of the connection depends on the power of your Wi-Fi router and interference in the air. To view video in high resolution (4K), it is recommended to use a 5 GHz network, as it provides more bandwidth and is less susceptible to interference from neighboring networks and household appliances.
⚠️ Warning: Some antivirus apps or firewall settings on the router may block the local connection between your phone and your TV. If device search doesn't work, try temporarily disabling protection.
☑️ Checking before connection
Comparison of methods of image output
Users often confuse different technologies for content transfer, considering them the same. However, there are significant differences between “Translation”, Chromecast and DLNA, which affect the usability and quality of the picture. Understanding these nuances will help you choose the best way for your task.
Built-in Translation (formerly Miracast) completely duplicates the screen of the smartphone. Everything that happens on the phone is displayed on the TV, including notifications, calls and the desktop interface. Chromecast, on the contrary, works differently: the phone acts as a remote, sending a link to the stream that the TV plays itself, which saves the battery of the phone.
DLNA is another standard often used in applications like Mi Video or VLC, which allows you to only transfer media files (photos, videos, music) stored in the device’s memory, but does not duplicate the system interface.
| Characteristics | Broadcast (Miracast) | Chromecast built-in | DLNA |
|---|---|---|---|
| Screen duplication | Complete (100%) | Only the content of the application | Media files only |
| Dependence on the phone | High (screen on fire) | Low (can be rolled) | Low. |
| Image quality | Depends on the Wi-Fi signal. | Maximum (streaming) | Original file |
| Sound. | It's on TV. | It's on TV. | It's on TV. |
Broadcasting content from apps (YouTube, Netflix)
Special attention should be paid to the broadcast from specific applications, such as YouTube, Netflix or online cinemas, in which case you do not need to enable the system function “Translation” in the phone settings, just open the video in the application, click on the icon Cast (rectangle with waves in the corner) and select your TV.
This is preferable because it doesn't load the smartphone processor or drain the battery. Videos are buffered directly by the TV, so even if you fold the app or lock the phone, the playback won't stop. It's perfect for watching movies.
However, if the app doesn’t support built-in Cast (like pirated online cinemas or a browser), then you’ll have to resort to full screen duplication through the system’s Translation. In this case, Mi Video (Mi Player) also has a built-in feature that can find devices not visible by standard Android tools.
- 🎬 YouTube: Click the Cast icon in the video player.
- 🎞️ Gallery: Open the photo/video → Share button or Translate button».
- 🌐 Browser: Some browsers (Chrome) allow you to broadcast the entire tab.
Remedy: The phone doesn't see the TV
The most common problem is when you start searching for devices, but the list is empty. First of all, check if Bluetooth is on on your smartphone. Although the transmission is over Wi-Fi, the device discovery protocol often uses Bluetooth Low Energy to find neighbors. Without Bluetooth enabled, the search may not work.
A second common reason is router frequency separation: If your phone is connected to a 2.4 GHz network and your TV (or set-top box) is running on a 5 GHz network, they may not be able to "see" each other even if the router is one. Try combining networks or temporarily switching both devices to the same frequency.
It's also worth checking the date and time settings. If the phone and TV have very different times, security certificates can block the connection. Set up automatic time synchronization in the Date and Time settings on both devices.
⚠️ Note: When using Guest Wi-Fi in public places or offices, the broadcast will not work, as these networks isolate devices from each other for security reasons.
Hidden Opportunities and Engineering Menu
For advanced users, there is an opportunity to improve the quality of the broadcast through the engineering menu or ADB-For example, you can change the resolution of the transmitted stream or the priority of the codecs. MIUI Usually optimal for 95% of users.
Some firmware versions have a hidden option called “Wi-Fi Accelerate” or “Game Turbo” for broadcasting, which will reserve bandwidth for video transfer, disabling background downloads. Check Game Turbo settings by adding the Translation or Mi Video app there, if such an option is available in your version.
If you're a developer, you might be interested in Wi-Fi debugging, but it's not necessary for the average user, but it's about having a stable signal and setting the router right, and remember that Xiaomi is constantly updating the software, and the functionality can change with the release of new versions of HyperOS.
