Modern TVs of the brand Xiaomi, working on the Android platform TV PatchWall, or PatchWall, are powerful multimedia centers that perfectly complement the mobile ecosystem, and the ability to instantly stream content from your smartphone to the big screen makes watching photo albums, presentations, or online videos a comfortable experience for the whole family. Users no longer need to look at the display of the gadget, when you can display the picture in high resolution 4K.
There are several proven ways to broadcast the screen, each with its own features and software requirements, depending on your TV model, the version of the Android operating system, and which smartphone you use, whether it is Android or iOS. In this article, we will discuss in detail all available options for syncing devices.
To get started, you will need a stable connection, as real-time video streaming requires good channel bandwidth. Wi-Fi router should support 802.11n or higher standards to ensure a smooth picture without delays and compression artifacts. If the network is overloaded with other devices, image quality may decline, so it is recommended to use a frequency of 5 GHz.
Device preparation and network setup
The first and most critical step is to ensure that both devices share a single network space, meaning that both the phone and the TV must be connected to the same router. If you have a dual-band router, make sure that both devices are on the same subnet, even if one is connected to 2.4 GHz and the other to 5 GHz.
On a Xiaomi TV, you need to activate the signal reception function. Depending on the firmware (Global or China version), this module can be called differently. It is usually built into the system and does not require additional software, but you need to find it on the menu.
- 📡 Make sure that both devices have Wi-Fi enabled.
- 🔒 Check that devices see each other on the LAN (turn off customer isolation on the router if it is active).
- 🔄 Update your TV firmware to the latest version via the Settings menu → On TV. → System update.
- 📱 On your smartphone, allow access to geolocation, as in Android it is required to find devices nearby.
⚠️ Note: If you are using a guest Wi-Fi network or corporate Internet with authorization through a web page, a direct connection may not be established.
Once connected to the network, check if the router is activated with AP Isolation, a security feature that prevents devices from communicating with each other on the network, making it impossible for the phone to detect the TV, and you can turn it off in the router settings via the web interface.
Use of the built-in Chromecast feature
Xiaomi’s Google-certified TVs officially support Chromecast built-in technology. This is the most stable and energy-efficient way to transfer content, since the TV itself downloads video streams from the Internet, and the phone acts only as a remote control. You do not need to keep the smartphone screen on while watching.
To start the broadcast, open an application that supports this feature, such as YouTube, Netflix or Google Chrome. Find the icon of the rectangle with waves in the corner (usually in the upper or lower right corner of the interface).
☑️ Checking before launching Chromecast
If you're streaming a Chrome tab, you can display an entire site or a specific video, and the quality of the image will depend on the Internet connection speed of the TV itself, not the phone, which is a huge plus, because the battery of the smartphone is minimal.
- 🎬 Open the supported application on your smartphone.
- 📺 Click on the broadcast icon and select your Xiaomi name TV.
- ⏯️ Use your phone as a remote: adjust volume, pause or rewind video.
It’s important to understand the difference between casting (broadcasting content from an app) and mirroring (copying the entire screen). Chromecast is primarily designed for the former. If you need to show a desktop, settings, or game that doesn’t support video output, this method may not work.
Screenplay via Miracast (Wireless Display)
Miracast technology allows you to create a direct connection between screens by transmitting a video signal in real time. On Xiaomi devices, this feature is often hidden in the Translation or Wireless Display app. Unlike the Chromecast, here the phone encodes an image and sends it to TV, which creates a minimal latency, ideal for demonstrating the interface.
To start the process, look for the Wireless Display or Broadcast app on the main TV screen. After you start, the screen will wait for connection. On your Android smartphone, go to the settings, Connected Devices → Connect to the device (the name may vary depending on the MIUI or HyperOS shell).
Your TV should appear on the list of available devices. Once paired, the smartphone image will appear on the big screen. The resolution will adjust automatically, but you can change it in the phone settings to achieve better definition.
| Parameter | Miracast (Translation) | Chromecast (Casting) |
|---|---|---|
| Type of transmission | Screen mirroring (screencast) | Linked streaming |
| Dependence on the phone | High (screen burns, battery goes down) | Low (the phone works like a remote) |
| Delay (Latency) | Minimum | Notable (several seconds) |
| Quality. | Depends on the power of the phone. | Maximum (up to 4K HDR) |
What to do if the TV is not on?
It is worth noting that when using Miracast, the phone can heat up, since the processor actively encodes the video stream. 1080p or 4K screen resolution requires significant computing resources. It is recommended to keep the smartphone charged or connect it to a power source.
Third-party apps for Android and iOS
If the built-in tools are unstable or your TV model does not support the right protocols out of the box, third-party solutions come to the rescue. For the Android TV platform, there are many receiver applications available in the Google Play Store that emulate the work of AirPlay or Miracast.
One of the most popular solutions is the AirScreen app, which allows you to stream images from iPhones (via AirPlay) and Android devices to Xiaomi TVs, and once you install the app on TV, it will appear on the list of available output devices.
- 📲 Install a receiver application (such as AirScreen or TV Cast on TV via Google Play.
- 🔗 Launch the app and wait for it to appear QR-code.
- 📶 On the phone, select the broadcast mode and find the name specified in the app on TV.
For iPhone owners, AirPlay technology is native, but Xiaomi TVs (except the newest models with Apple certification) often require emulator installation. Once you install such an emulator on TV, you can use the standard feature "Screen Replay" in the iOS control center.
💡
To reduce latency when playing mobile games on your TV via broadcast, turn off background downloads on your phone and close the unnecessary applications, which will free up the CPU resources to encode the video stream.
There are also phone client apps like Google Home or Mi Remote, which allow you to not only stream media files from your device’s memory (DLNA), but also control your TV. The screen throw feature in the Google Home app works on most Android smartphones and is a versatile tool.
Transfer of photos and videos over DLNA and local area network
When you don't have to live stream the entire screen, but you just have to show a birthday photo or a video taken on camera, you can use DLNA, which doesn't put a strain on the phone's processor, because it sends a file that's already there.
On Xiaomi TV, run the Media Player or Gallery app. From the signal sources, select your computer or smartphone. From the gallery phone, select the photo or video you want, click Share, and select the Translate or TV icon option.
Files will be buffered and played on the TV, and the advantage of this method is that it's a high quality source file without the additional compression that inevitably occurs when you mirror the screen, and you can continue to use the phone for other tasks while the video is played on the big screen.
Solving Connection Problems
Despite the simplicity of the technology, users often face difficulties, and the most common problem is that the TV is not visible on the list of available devices, which almost always indicates a problem with the network or the router's security settings.
If you have a connection, but the picture is twitching or falling into squares, you don't have enough bandwidth. Try to get closer to the router or switch to the 5 GHz band. Also, the reason may be overheating of the smartphone, which causes the system to reduce the frequency of the processor.
⚠️ Attention: When in use VPN On a smartphone, the local network may become undetectable. VPN-services before attempting to connect to the TV.
In some cases, resetting the network settings on the TV helps: Go to Settings → Network and Internet, select your network and click Forget. Then reconnect by entering the password. This will clear the network settings cache and can fix protocol errors.
