Modern tech owners often wonder how to display images from a mobile device to a large screen without unnecessary wires. Miracast technology has become the standard for wireless broadcasting, allowing you to duplicate the screen of a smartphone or tablet on a TV in real time. In Xiaomi devices, this feature is built deep into the Android TV or PatchWall operating system, but its location is not always obvious at first glance.
Many users get lost in the abundance of icons and settings, not understanding why their phone can’t see the TV. Often the problem lies not in the lack of support for the standard, but in the wrong name of the feature in the menu or hidden mode. Understanding exactly how the Miracast protocol is renamed in the shell of Xiaomi is the key to quickly configuring the multimedia system.
In this article, we will discuss in detail the algorithms for finding a function, the features of working in different versions of firmware, and the nuances that can prevent stable connection, you will learn how to activate the broadcast mode and what alternatives exist if the standard method for some reason does not work.
Search for Miracast function in the TV interface
The first thing to know is that you will rarely find the direct name "Miracast" on Xiaomi TVs. The company's engineers prefer to use more user-friendly terms such as "Wireless Screen," "Translation" or "Wireless Display." Search should start from the main menu using the remote control.
Click the menu button on the remote and go to the settings section. Usually the icon looks like a gear. Inside the Settings section, you will need to find a subsection related to network connections or external devices. Depending on the version of the PatchWall shell or pure Android TV, the path may vary slightly.
If you're using the current version of the software, the system might suggest that you turn on the function automatically when you try to connect from an external device. However, manual start-up is often more reliable. Go to Settings → Device → Wireless connections (or similar). This is where the switch that activates the signal reception is hidden.
Why can a function be called differently?
In some models, especially budget or older versions, the feature can be brought to a separate app on the home screen.Look for an icon called Wireless Display or Cast. Launching this app puts the TV in standby mode.
Activation of the broadcast mode through network settings
It's not enough to find a menu to connect successfully, you need to configure network settings correctly. Miracast's technology is powered by Wi-Fi Direct, which means connecting devices directly without the router, although both devices often need to be on the same local network for an initial handshake.
Go to the network settings section of your TV. Make sure that the Wi-Fi module is active. Even if you use an Ethernet cable connection, the wireless module must be turned on to run Miracast. In the Network and Internet menu, check the connection status.
💡
For maximum 4K image stability, try to connect both the TV and smartphone to the 5GHz Wi-Fi range, as long as your router supports dual-band operation.
Next, you need to find the point responsible for the visibility of the device, which can be called "Screen Translation", "Projection" or "Connected devices." When activated, the TV starts sending out detection packets, allowing the smartphone to see the Xiaomi Mi TV in the list of available displays.
Importantly, newer versions of Android TV firmware 9.0 and higher have made the process even more automated, and the system itself determines the type of device to be connected and suggests the appropriate protocol, but if automation fails, manually running through the settings menu remains the most reliable way.
☑️ Checking connection readiness
Setting up a smartphone to connect to Xiaomi TV
Once the TV is ready to receive the signal, you need to configure the source of the image – your smartphone. The process may vary depending on the phone manufacturer (Samsung, Xiaomi, Huawei) and the version of the Android operating system.
In Xiaomi smartphones with MIUI or HyperOS shells, the feature is called Translation. It is in the notification curtain (control menu) or in the screen settings. Click on the icon and the phone will start searching for available devices within range.
Samsung devices use Smart View technology, you have to open the menu curtain, find the appropriate icon, and select your TV from the list. Other brands may use the names "Projection", "Translation" or "Connect".
- 📱 Open screen settings or quick actions on your smartphone.
- 📡 Make sure that Wi-Fi is on and active.
- 🔍 Click "Device Search" or "Translation".
- ✅ Choose your Xiaomi TV from the list that appears.
When you first connect to your TV, you may see a confirmation request, use the remote to agree to the connection, and then the image from your smartphone will be broadcast to the big screen with minimal latency.
Use of the built-in Chromecast app
In addition to native Miracast, Xiaomi TVs feature built-in support for Google Cast (Chromecast built-in) technology, an alternative and often more stable way to stream content, especially for videos from apps like YouTube or Netflix.
Unlike Miracast, which duplicates the entire screen of a smartphone, Chromecast allows you to stream specific content directly from the app using the TV’s Internet channel.This reduces the load on the phone’s battery and often provides better picture quality.
To use this feature, make sure your TV runs the Chromecast built-in app (often built-in) or simply has standby mode on. In apps on your phone, look for the rectangle icon with the waves in the corner.
💡
Chromecast often works more stable than Miracast when watching online video, as the TV loads the stream independently, regardless of the power of the smartphone’s processor.
If you want to broadcast a screen (for example, for presentations or games), then in the Google Home app on your smartphone, you can select your TV and click on the Translate screen button. This uses the Cast protocol, but the visual result is similar to Miracast.
Solving Device Detection Problems
The situation when the Xiaomi TV is not visible in the list of available devices is one of the most common, most often due to network security settings or outdated software.
Check if the router is enabled with AP Isolation, which prevents devices on the same Wi-Fi network from communicating with each other, making it impossible for Miracast to work. Also make sure that the antivirus or firewall on your smartphone does not block local connections.
| Problem. | Possible cause | Decision |
|---|---|---|
| TV not found | Different Wi-Fi networks | Check the SSID network on both devices |
| Lags and delays | Weak Wi-Fi signal | Get closer to the router or use 5GHz |
| No sound. | Incorrect audio output | Select HDMI/CEC or Bluetooth in the audio settings |
| Black screen | Codec incompatibility | Update the source app or TV software |
Another important factor is the version of the Wi-Fi module drivers in the TV. Manufacturers regularly release updates to fix data protocol errors. Go to Settings → About TV → System Update and check for a new version of the software.
⚠️ Note: If you use a guest Wi-Fi network, devices can be isolated from each other at the router level. To work Miracast, be sure to connect your phone and TV to the main network.
Alternative ways of connecting and applications
If the built-in tools don’t work or the functionality isn’t enough, the Android ecosystem offers a host of third-party solutions, and aggregator apps can provide compatibility with even very old TV models or specific file formats.
A popular solution is to install the AirScreen or Receiver for Chromecast app directly on your TV through the Google Play Store.These programs emulate different reception protocols, making your Xiaomi TV visible to Apple devices (AirPlay) or other brands.
- 📺 AirScreen: Great for iPhone (AirPlay) and Android device owners.
- 🎮 GameStream: Specialized applications for low latency games.
- 📂 LocalCast: To stream files from the phone’s internal memory.
For advanced users, a USB or ADB debugging method is available to install system components that improve wireless interfaces, but this requires a computer and some technical knowledge.
⚠️ Note: When installing third-party receiver applications on your TV, pay attention to the permissions requested. Some programs may require access to the microphone or file system without an explicit need to.
