Xiaomi’s modern smartphones have powerful screens that allow users to consume content and display it on a large display. Wireless image duplication has become the de facto standard for presentations, movie watching and even mobile games. Users often look for a way to stream the contents of their gadget screen to the TV without the need for extra cables and adapters.
In the Android ecosystem, this feature is known by different names: Miracast, Wireless Monitor, Translation or Cast. Despite the variety of terms, the principle of operation remains the same: creating a direct Wi-Fi connection between the output device and the smartphone. On Redmi and POCO devices, the setup process can have its own nuances, depending on the version of the MIUI shell or HyperOS.
In this article, we will discuss all the available methods of activating the function, from standard system settings to using third-party utilities. You will learn how to fix common connection problems and why your TV may not see your phone.
What is Miracast Technology and How Does It Work?
Miracast is a wireless media standard developed by the Wi-Fi Alliance. Unlike Chromecast, which requires the Internet and Google servers to manage the flow, the technology creates direct media. P2P-Peer-to-Peer connection – This means your Xiaomi and TV are communicating directly, bypassing the router, although for an initial handshake, devices often need to be on the same network.
The principle of operation is to compress the video stream in real time and transmit it over the Wi-Fi Direct protocol. The smartphone encodes the image from the screen, and the receiving device (television, projector or set-top box) decodes it and displays it, while the delay is minimal, which allows you to use the connection not only for video, but also for the demonstration of games.
⚠️ Attention: The quality of the transmitted image depends on the power of the Wi-Fi modules of both devices and the presence of interference in the air. If you are near a microwave oven or a powerful router at the same frequency, artifacts are possible.
It is important to understand the difference between built-in system function and aggregator applications. Xiaomi owners often confuse the system broadcast screen with the function of “Translation” in applications like YouTube. System Miracast duplicates absolutely everything that happens on the screen, including notifications, desktop and menus, while DLNA or Chromecast only transfers a specific media file from the application.

Miracast creates a direct Wi-Fi Direct connection without consuming mobile Internet traffic or loading the router’s local network with heavy traffic.
Checking the compatibility of devices before connecting
Before you start setting up, you need to make sure that both devices support the required standard. Virtually all modern TVs with Smart TVs (Samsung, LG, Sony, Philips, Xiaomi Mi TV) have a built-in signal receiver. However, older models may require an external adapter, such as a Microsoft Wireless Display Adapter or similar dongle device.
On the smartphone side, Xiaomi has built support for the technology into the Android core since version 4.2, but the management interface can be hidden by the manufacturer. In the MIUI shell, the functionality is often renamed Translation or Wireless Monitor. Make sure your TV has a signal reception feature that is differently called Screen Share, Anyview Cast, Smart View or simply Miracast.
For successful connectivity, it is critical that both devices are within a safe signal reception zone, the distance should not exceed 5-7 meters without obstacles, and also make sure that the TV does not run heavy background processes that can prevent the creation of a new Wi-Fi Direct connection.
| The device | Name of function | Location on the menu | Required version of the software |
|---|---|---|---|
| Xiaomi / Redmi | Broadcast / Wireless monitor | Control Panel / Settings | Android 4.2+ |
| Samsung TV | Screen Mirroring | Source (Source) | Tizen OS |
| LG TV | Screen Share | Home menu | WebOS |
| Sony / Philips | Screen duplication | Entrances/Applications | Android TV |
If your TV is old and doesn’t have a smart TV TV, Don't be too upset. The market offers a lot of things. HDMI-And these are adapters that add this function. They're inserted into the port. HDMI and eat from USB, Turning a regular monitor into a signal receiver.
Standard method of activation through the control panel
The fastest way to enable screen duplication on Xiaomi is to use notification curtains. However, in the newer versions of HyperOS and MIUI 14, the icon can be hidden by default. To activate it, you need to deploy the swipe control panel down from the upper right corner (or top down, depending on the settings).
Find an icon called Translation, Wireless Monitor, or arrow screen icon. If you don't see the item visually, click on the edit button (usually a pencil icon or a tripod). In the list of available widgets, find the one you want and drag it to the active area, and then it becomes available for quick access.
☑️ Translation Including Algorithm
Once the button is activated, the phone will start scanning the available devices. Make sure your TV is put in standby mode (often you need to run the Screen Share app on the TV itself). When your TV name appears on the list on your smartphone, just tap it. A request for connection permission may appear on the TV screen, which must be confirmed by the remote.
⚠️ Warning: If you see a message saying "Devices not found" after pressing the button, check if the Wi-Fi on your smartphone is on. Although the Internet is not mandatory, the wireless module must be active.
Configure through the system menu "Settings"
If the fast access doesn't work or the interface is changed, you can use deep system settings. The path may vary depending on the firmware version, but the logic remains the same. You need to open the main settings menu and find the section responsible for connecting external displays.
Go to Connect and Sharing (or “Additional Features” in older versions) and look for “Translation” or “Wireless Display” where some MIUI builds for the global market may call this item Cast, and clicking on it will get you into the device search menu.
This menu also often provides a device name setting, and by default, the phone can be called “Xiaomi” or a device model (e.g., “Redmi Note”). 12»). For easy identification in the general network, it is better to rename the gadget into something recognizable, for example, «Phone_LivingRoom». This is especially true if you are in an office or public place.
Hidden Developer Settings
Once you select the TV, you'll start pairing. The screen of the smartphone may go out for a few seconds, after which the image will appear on the large display. Note that the orientation of the image (portrait or landscape) will change automatically depending on the position of the phone, unless you have a lock on the rotation.
Use of Mi Remote and third-party utilities
Xiaomi’s ecosystem preinstalled Mi Remote (Mi Remote) app, although its primary focus is on managing the IR port, in some versions it is integrated with smart home features and can help detect devices, but live screen broadcasts are more likely to use specialized apps if the standard feature fails.
A popular solution is Web Video Caster or LocalCast, which allows you to broadcast not only the entire screen, but also specific video, photo or music files with support for subtitles and audio track selection, which is a great option if the built-in Miracast is unstable or does not support a certain audio codec format.
For advanced users who want to stream a computer screen to their phone or vice versa, there is a Scrcpy program, but it requires a USB connection and debugging settings. For wireless transmission from a PC to Xiaomi, you can use the built-in Windows 10/11 “Project to this PC” feature, which is also based on the Miracast protocol.
It’s worth noting that third-party apps can add latency, which is not critical to watching movies, but it’s better to use native system tools for games, and some apps require a server-side set to the TV, which is not always convenient.
The solution to the problem: the phone can’t see the TV
One of the most common problems is when devices are on the same network but can't see each other. Often the reason lies in router settings. If you have a dual-band router, make sure both devices are connected to the same frequency (either both at 2.4 GHz or both at 5 GHz).
The second common reason is that AP Isolation is enabled in the router settings, which prevents devices on the network from sharing data with each other, allowing only Internet access. Miracast requires that this feature be disabled in the router's admin panel to work.
Problems can also arise from outdated Wi-Fi drivers. Check for system updates in the About Phone section. Sometimes it helps to simply restart network settings: go to Settings → Connection and Sharing → Reset Wi-Fi, mobile networks and Bluetooth.
⚠️ Note: When you reset your network settings, all stored Wi-Fi passwords and Bluetooth pairs will be deleted. Make sure you remember passwords from your networks before performing this operation.
If nothing works, try creating a hotspot on another phone and connecting to it, but this rarely helps in the case of Miracast, since the technology requires Wi-Fi Direct, not just a shared network. HDMI-Type-C Cable Adapter to HDMI It will be a guaranteed, though wired solution.
The effect of broadcasting on battery and performance
High-resolution active video streaming is a resource-intensive process. The video encoder loads the processor, and the constant operation of the Wi-Fi module to transmit data quickly consumes battery power. During long broadcast sessions, the phone can significantly heat up, leading to trotting (reduced processor frequency) and a drop in FPS in games.
To minimize heat, it is recommended to reduce the brightness of the smartphone screen during broadcast, since the image on the phone itself may still not be necessary.
💡
If you plan to watch a movie over a long time via Miracast, connect your smartphone to the charger, and use the original charger to avoid overheating from poor-quality current.
The resolution of the image being transmitted also plays a role. In the broadcast settings (if available in your version of MIUI), you can try to reduce the quality from Full HD to HD if you notice the twitching of the image, which will reduce the load on the transmission channel and the processor.
