Xiaomi’s modern smart TVs, which run on Android TV or PatchWall, offer a wide range of multimedia capabilities. One key feature is wireless image broadcasting technology, often referred to as Airscreen or Miracast, which allows you to display the contents of your smartphone, tablet or laptop screen on a large diagonal without using extra wires.
Users often confuse different data protocols such as Chromecast, AirPlay, and Miracast, however, in the context of Xiaomi devices, the term Airscreen usually refers to the native wireless display protocol. This solution is ideal for showing presentations, viewing photos from the gallery or running videos from applications that do not support direct output to the Internet. DLNA-server.
In this article, we will discuss the process of activating the function, setting quality parameters and how to eliminate common connection errors. Understanding the principles of wireless display will help you to maximize the potential of your technology.
What is Airscreen Technology in Xiaomi Ecosystem
The technology behind the Airscreen name in Xiaomi TVs is based on the Wi-Fi Direct standard. Unlike the Chromecast, which requires a controller app and an active Wi-Fi network to control the flow, Airscreen creates a direct connection between devices, which means that your smartphone and TV share video stream directly, bypassing the router, although for the initial handshake they often need to be on the same local network.
The main advantage of this method is low latency and versatility. You do not need special applications on the phone when it comes to Android devices, since the feature is built into the system. iPhone owners also have support through the AirPlay protocol, which in the new Xiaomi TV models is integrated into the same signal reception module.
⚠️ Attention: The quality of the broadcast depends on the power of the Wi-Fi signal of the modules of both devices. The presence of thick walls or a working microwave oven can cause artifacts on the screen.
It's important to understand that Airscreen is broadcasting exactly what's happening on your gadget's screen, and if you switch the app on your phone, the image will change on your TV, which is different from DLNA, where the TV downloads the file over the network and the phone is just a remote control.
Equipment preparation and network requirements
Before you start setting up, you need to make sure that your hardware meets the minimum technical requirements, primarily the version of the operating system and the status of the wireless module. Outdated firmware may not contain the necessary drivers for the stable operation of the Miracast protocol.
Both your Xiaomi TV and your smartphone must be connected to the same Wi-Fi network. This is a critical point, since the device detection protocol works within the local subnet. If your router distributes networks at 2.4 GHz and 5 GHz with different names, make sure that the gadgets are connected to the same ones.
- 📺 Xiaomi TV should be on and running on the current version MIUI TV Android TV.
- 📱 The smartphone should support the function of “Wireless display”, “Translation” or “Smart View».
- 📶 Stable Wi-Fi connection without router-level restrictions (e.g., customer isolation) AP Isolation must be disabled).
It's also worth checking if the link is congested, and if you have dozens of devices that are actively uploading torrents or watching 4K video at the same time, you may not have enough bandwidth to transmit a picture in high resolution, and then you may have delays and desynchronization of the sound.
💡
For maximum stability, it is recommended to connect the Xiaomi TV to a 5 GHz network, as this range is less congested and provides a higher data rate.
Activation of the feature on the Xiaomi TV
The process of enabling reception on Xiaomi TVs may vary slightly depending on the version of the operating system installed. In most cases, you do not need to run a separate application, since the service runs in the background, but access to the menu is necessary for the initial setup.
On the remote, click the app menu button or go to the settings section. You need to find the external device connection item. Depending on the regional version of the firmware, it can be called differently. Often the name is Wireless Connection or Projector.
After entering the menu, you will see a waiting screen with the name of your TV and, possibly, the screen, PIN-If you see the word "Waiting for Connection," it means that the Wi-Fi Direct module is active and ready to pair.
Settings → Device → Wireless display (or Miracast)Some models allow you to configure security settings, you can set a requirement to confirm your connection from the remote or set a static code, which is a useful feature if you use a TV in an office or public place so that outsiders can not display the image on your screen.
☑️ Checking before connection
Instructions for connecting an Android smartphone
Android device owners have the most options to implement the connection. The interface may differ from manufacturer to manufacturer (Samsung, Huawei, Pixel), but the logic of action remains the same. You need to find the quick settings or menu feature broadcast screen.
Open the swipe notification curtain from top to bottom and find the Translation, Smart View, Cast, or Wireless Projector icon. If it's not in the curtain, click on the edit button (usually three dots or a pencil) and add a widget from the list of available ones. Once launched, you'll start looking for available devices within range.
The list of devices found should show the name of your Xiaomi TV. Click on it. The TV screen may have a request for confirmation of connection — use the remote to agree. In a few seconds, the image from the phone will appear on the big screen.
- 🔍 Open your phone settings and search for “Translation” or “Cast».
- 📡 Wait until the system finds your Xiaomi TV in the list of available devices.
- ✅ Confirm the connection on the TV screen if required.
It is worth noting that when connected via Wi-Fi Direct, the phone can temporarily lose access to the Internet if it does not support the simultaneous operation of two Wi-Fi channels. In modern flagship models, this problem is solved, but on budget devices, the Internet can disappear until the connection with the TV is broken.
⚠️ Attention: When the screen is broadcasting, the smartphone battery discharges much faster due to the high load on the processor and radio module.
Broadcast from Apple devices (iOS and macOS)
Users of the Apple ecosystem may find that the standard Miracast protocol is not supported out of the box on iPhones.However, modern Xiaomi TVs often have built-in AirPlay 2 support. If your TV model is fresh, you don't need additional apps.
To check, make sure that the TV is enabled with AirPlay. This is usually a separate switch in the settings or the AirPlay app in the list of programs. After turning on the iPhone, you need to open the Control Point (swipe from top to bottom on FaceID models or from bottom to bottom on models with a button) and click on the Screen Replay icon (two rectangles).
Select your Xiaomi TV from the list. If the devices are on the same network, the connection will be established automatically. An image from an iPhone or iPad will be duplicated on the TV. For Mac laptops, the action is similar: through the menu in the status bar, select the display and specify the TV.
What if AirPlay doesn’t work on Xiaomi?
However, latency may still be present, making this method not ideal for dynamic gaming, but great for viewing photos and videos.
Setting up image and sound parameters
Once you've successfully connected, you might notice that the picture doesn't take up the entire screen or has black fields around the edges, because of the difference in resolution and aspect ratio between the smartphone and the TV. Most TVs today automatically scale the image, but sometimes manual adjustments are required.
Go to the settings on the TV during the broadcast. Find the option "Screen shape" or "Special aspect ratio." Select "Screen size", "16:9" or "Original" to remove stretching. It is not recommended to choose "Zoom" or "Wide" mode, as this will lead to cropping of the edges of the image.
| Parameter | Recommended value | Impact on quality |
|---|---|---|
| Permission | 1920x1080 or 4K | Clearness of picture |
| Frequency of personnel | 60 Hz | Smoothness of movement |
| HDR mode | Auto/On | Color reproduction and contrast |
| Sound. | PCM/Auto | No audio delay |
Sound deserves special attention. Sometimes the audio stream may not be transmitted to the TV, remaining on the speaker of the phone. In the broadcast menu on your smartphone, check the selection of the output device and specify the TV. If the sound wheezes or interrupts, try to reduce the audio quality in the settings. Bluetooth/Wi-Fi module, if such option is available in the engineering menu.
💡
The optimal ratio of quality to performance is achieved at 1080p resolution and 60Hz frequency, which reduces the load on the network and minimizes the lag.
Solution: Problems and ways to eliminate them
Even with the right setup, users can face difficulties, and the most common problem is that the TV can't see the phone, and 90 percent of the time, it's solved by rebooting the router, because the detection protocols could be stuck in the router's ARP table.
If there is an image but no sound, check the mixer settings on the TV. Sometimes the system mistakenly switches the output to a Bluetooth headset if it was paired before. Turn off the extra devices in the Settings → Sound → Exit menu.
If you're constantly out of communication or croaking, you might be getting a weak signal, you might be closer to your router or your TV, you might want to try to free up your Wi-Fi channel by disconnecting devices that aren't currently in use, or at least reset your TV settings to the factory.
- 🔄 Reboot both devices and router – it solves most software conflicts.
- 📶 Make sure that the router does not include filtering by MAC-address.
- 📉 Reduce the resolution of the broadcast in the phone settings if the network is congested.
⚠️ Note: If the problem persists after all the manipulations, it is possible that the antivirus on the smartphone or firewall on the router will block the ports necessary for Miracast to work (usually ports 7236, 7250).
