Modern smartphones Xiaomi, Redmi and Poco have powerful multimedia capabilities that allow you to broadcast content to a large screen TV without the use of unnecessary cables. Miracast technology, built into the shell of MIUI and HyperOS, allows you to duplicate images from a mobile device to any compatible display in seconds, this is especially convenient for watching movies, photos or presentations in the office.
However, users often have difficulty finding a feature that can be called differently depending on the firmware version or region. In some cases, the menu is hidden, and in others, additional settings are required to be activated. In this article, we will discuss in detail how to find and run a wireless display, and also eliminate typical connection errors.
It's critical to synchronize successfully, that both devices are on the same LAN or have a direct Wi-Fi connection. It works at the Wi-Fi Direct protocol level, so a router isn't always mandatory if the TV supports a direct connection. Let's look at the algorithm for different use cases.
Preparation of devices for wireless connection
Before trying to find the settings of the broadcast, you need to make sure that the network equipment works correctly. The smartphone and the TV should “see” each other on the air. If you use a home router, check that both gadgets are connected to the main network, and not to the guest, since customer isolation can block the transmission of the video stream.
Note the software version of your TV. Older Smart TV models may not support the modern video coding standards used by newer Xiaomi phones. In such cases, you may need to update the firmware of the TV itself through its system menu.
Also worth checking is the battery power of your smartphone. streaming video in high resolution 1080p or 4K significantly increases the power consumption of the processor and Wi-Fi module. It is recommended to keep the device on charge or make sure that the charge level exceeds 50%.
⚠️ Note: When you first connect, Android security may ask permission to record the screen. This is the standard behavior required to capture the image, and it does not mean the presence of viruses.
Make sure the app is running on the TV. On Samsung devices, it could be Screen Mirroring, on LG, it could be Screen Share, and on Android TV, it could be a built-in Cast receiver. Without active standby on the TV side, the phone wouldn't be able to detect the target device.
Search for Wireless Display Function in MIUI and HyperOS
Depending on the version of the shell, the path to the desired option may differ: in modern versions of HyperOS and recent builds of MIUI, the function is often renamed or moved for the convenience of users.
Swipe down from the top right corner of the screen to open the control panel. Find an icon called Translation or Cast. If the icon is not on the visible part of the screen, click on the edit button (usually three dots or a pencil) and drag the desired widget to the active zone.
An alternative way to search is through system settings. Go to Settings menu → Connection and Sharing → Broadcast. Here you can activate the function forcefully and see a list of available devices in range.
☑️ Checking before connection
If you're using a global firmware version, the name of the feature might be Wireless Display. In Chinese versions (CN), it's often called Wireless Monitor. It's important not to confuse this feature with Google Home, although they have similar operating principles, but the protocols for data transfer may differ.
Algorithm of connecting a smartphone to a TV
Once the function is activated, the smartphone will automatically search for available receivers, the scanning process can take from 5 to 15 seconds, and the list will display all devices ready for pairing, including TVs, Chromecast consoles and projectors.
Select the name of your TV from the list. The TV screen may be prompted to confirm your connection. Use the remote control to agree to the action. After that, the image from the smartphone will be duplicated on the large screen.
To ensure a stable connection, follow the simple rules:
- 📶 Get closer to the router if the Wi-Fi signal is weak to avoid delays.
- 📱 Close heavy applications in the background to free up RAM.
- 🔋 Turn off energy saving while watching high-quality video.
In some cases, it may be necessary to enter PIN-Enter the combination of numbers on your smartphone to complete the pairing. This is a measure of protection against unauthorized access to your screen.
| Parameter | Requirement | Recommendation |
|---|---|---|
| Wi-Fi frequency | 2.4 GHz / 5 GHz | Use 5 GHz for 4K video |
| Distance | Up to 10 meters. | Direct router visibility |
| Android version | 4.2 and above | Up-to-date version of MIUI |
| Video format | H.264 / H.265 | Depends on TV support |
What to do if the list of devices is empty?
Customization of image and sound quality
Once you've successfully connected, you may find that the image doesn't take up the entire screen or the sound comes only from your phone. Xiaomi's broadcast settings often have the option to change the orientation of the screen. If the picture is reversed, block the autorotation on your phone or use the corresponding button in the broadcast menu.
To adjust the audio, make sure that the output device is the TV. Often when you connect through Miracast, the sound switches automatically, but applications like YouTube or Netflix may have their own audio output settings. Check if the phone is silent, as system sounds can interfere with the perception of content.
If you notice audio and video (lipsync) desynchronization, try to reduce the quality of the stream in the source application settings, and switching the router’s Wi-Fi channel frequency to a less loaded one can also help to reduce signal interference.
⚠️ Note: When broadcasting protected content (DRM) And through some apps, the TV can display a black screen instead of a video, which is a restriction of copyright policy, not a malfunction of the phone.
Some TVs allow you to adjust the aspect ratio (Aspect Ratio). If there are black stripes on the sides of the screen, use the TV remote to stretch the image to 16:9 or Just Scan, excluding the edge trimming.
Use of third-party broadcasting applications
Xiaomi’s built-in tools work well, but not always perfect.If the standard Wireless Display feature doesn’t find your TV or isn’t working smoothly, you can use the proven third-party solutions from Google Play.
The popular Web Video Caster app allows you to stream video directly from your phone’s browser, bypassing system limitations, often addressing video format playback problems that are not supported by the native TV player.
Another powerful tool is LocalCast, which can stream not only video files, but also photos, music and even documents, and it supports subtitles and allows you to control playback from your phone, which is very convenient.
- 📺 AllConnect is a universal player for DLNA AirPlay devices.
- 🎬 TV Cast – specializes in streaming from online cinema sites.
- 🖥️ ApowerMirror – allows you not only to broadcast, but also to manage your phone from a PC.
When using third-party software, make sure you give the necessary permissions to access the local network. Without this right, the application simply will not be able to detect devices on your Wi-Fi network.
💡
For low latency games, use Game mode in the broadcast settings, if available.This prioritizes the video stream, reducing input lag, although picture quality may decrease slightly.
Solving Typical Connection Problems and Errors
The most common problem is that the phone sees the TV, but the connection breaks down after a few seconds. This almost always indicates a weak Wi-Fi signal or a congestion channel. Try moving the router closer to the viewing area or switch to 5 GHz.
If the image is twitching or low resolution, check if the phone is running traffic saving mode, and also make sure that the TV is not running heavy background processes, such as system updates or downloading torrents.
In case the “Translation” function is completely absent from the menu:
- Check the region in your phone settings (for some regions, the feature is hidden).
- Install the Mi Remote app or update Google’s system components.
- Use the command via ADB to activate hidden features if you are an advanced user.
adb shell settings put global wifi_display_on 1This command, entered through a computer with an ADB installed, can force the Wi-Fi Display module on the system if it has been disabled by the manufacturer software.
⚠️ Attention: Use of teams ADB Misty input of parameters can lead to unstable operation of the network modules of the smartphone.
💡
The key to stable broadcasting is using 5GHz and the minimum distance between the router and the receiving device, which eliminates 90% of lag problems.
