Xiaomi’s modern Smart TVs offer a wide range of multimedia content options, but users often want to stream images directly from their mobile device or laptop. The screen duplication feature, also known as Miracast or Screen Cast, allows you to display everything that happens on the smartphone’s display, whether it’s watching photos, videos or even mobile games, which turns the TV into a full-fledged entertainment center without the need for additional cables.
The setup process can vary depending on the version of the Android TV or PatchWall operating system installed on your device, as well as the model of the smartphone itself. In some cases, the system works automatically, while in others it requires manual activation of services or installation of specialized software. Understanding the principles of wireless data protocols will help avoid typical connection errors.
In this guide, we will take a look at all the synchronization methods available, from built-in system tools to the use of third-party software. You will learn how to ensure a stable connection, what Wi-Fi settings are critical and how to solve problems if the TV does not see your device. To properly work Miracast function, both devices must be on the same Wi-Fi router subnet.
Built-in streaming tools on Android TV and PatchWall
Most Xiaomi Mi TVs run Android TV, which has built-in support for Google Cast technology.This means that it is enough to simply click on the appropriate icon within the app to transfer images from many apps, such as YouTube or Netflix. However, system functions must be used to completely duplicate the screen (mirror) of the smartphone interface.
Xiaomi TV remotes often have a button with a smartphone image or Cast label on them, and if you don't have one, you'll need to go to the main menu, select the App section, and find a system application called Wireless display or Broadcast, and launch this app and put the TV in compatible device search mode.
Android smartphone owners should open the Quick Settings Panel (curtain) and find the Broadcast, Smart View (for Samsung) or Projection. After scanning the network, your TV should appear on the list. On iPhone or iPad devices, the situation is a little more complicated, since native AirPlay support is not available on all Xiaomi models, but new firmware versions often include this protocol.
⚠️ Note: When using built-in broadcasting tools, make sure that the TV does not run heavy background processes that can cause image delay (lag) during games or watching dynamic video.
Use of Xiaomi Mi Remote and third-party services
If standard methods don’t work or require finer tuning, the official Xiaomi Mi Remote app or its MI Remote analogue, available on the Google Play Store, comes to the rescue. This tool allows you not only to control the TV as a remote control, but also to initiate the process of mirroring the screen. Once you install the application on your smartphone and connect to the same Wi-Fi network as the TV, the program automatically detects available Xiaomi devices.
For users whose devices do not support native Miracast or have limitations, installing third-party apps from the Google Play store on the TV itself is a great solution. Popular options are AirScreen, Receiver for AirPlay & Cast or ApowerMirror. These programs emulate the reception of signals from various protocols, making the TV visible for iOS and Android devices.
The process of installing third-party software is simple: you need to open the Google Play Store on your TV, enter the name of the application in search and click Install. QR-the code or device name to select in the smartphone settings. Some applications require input PIN-security code that prevents unauthorized access to your screen.
- 📲 AirScreen – Supports AirPlay, Google Cast, Miracast and DLNA, Perfect for iPhone owners.
- 📺 Cast to TV — simple application for fast broadcast of video files and photos from the gallery.
- 🎮 ApowerMirror – allows you to control your smartphone from the remote and has a low latency for games.
- 🔗 Web Video Caster – specializes in transferring video from browsers to the big screen.
💡
To reduce latency when playing mobile games on your TV, use a cable connection of your smartphone to the router via a USB-Ethernet adapter if the router is far from the TV.
Connecting Windows and macOS: Wired and Wireless Methods
Duplication of the computer screen on the Xiaomi TV may be required for presentations or viewing content in high resolution. Windows 10 and Windows 11 support Miracast technology. To connect, just press the Win + K key combination, then the Connect panel will appear on the right side of the screen. Your TV should be displayed in the list of available devices if it is running signal reception mode.
Mac OS users can use AirPlay technology if the TV model supports this protocol natively or through an installed emulator application (for example, the same AirScreen). In the AirPlay menu, accessible through the menu bar or control center, you need to choose a Xiaomi TV. It is important to note that stable operation in 4K resolution requires support for HDCP 2.2 and a fairly high speed Wi-Fi network.
If the wireless connection is unstable or the maximum picture quality without compression is required, you can use a cable connection. For modern Xiaomi laptops and TVs with an HDMI port, a conventional cable is enough. If the ports do not match (for example, only USB-C on a laptop), you will need an appropriate adapter. When connected with a cable, the TV will automatically switch to the selected signal source.
☑️ Checking before connecting the PC
When using wireless on Windows, there is sometimes a cursor delay problem, which is solved by switching projection mode. Press Win + P and select "Second Screen Only" if you want to fully transfer the image, or "Repeat" if you want to see the same thing on both devices. Expand mode will turn the TV into a second monitor, which is convenient for working with windows.
Setting up Wi-Fi network and eliminating interference
The quality of screen duplication depends on the state of the wireless network. Miracast and Google Cast transmit real-time video streaming, which requires stable channel bandwidth. If the router is running in an overloaded 2.4 GHz band, artifacts, image jerks or sound desynchronization can be observed. The optimal solution is to use the 5 GHz band.
It is important to consider the physical location of the devices. The router, TV and broadcast device should be in line of sight or through a minimum number of walls. Microwave ovens, baby monitors and other household appliances can interfere with the Wi-Fi frequency range, which negatively affects the transmission of the video signal. Rebooting the router before the start of the broadcast session often helps to clear the buffer and choose a free channel.
In the settings of the router, it is recommended to disable the function AP Isolation, if active, is designed to be secure on public networks and prevents devices within the same network from communicating with each other, making it impossible for a smartphone to detect a TV. It is also worth checking whether the speed limit is worth the specifics. MAC-address.
| Network parameter | Recommended value | Impact on broadcasting |
|---|---|---|
| Frequency range | 5 GHz | High speed, less interference |
| Security protocol | WPA2/WPA3 | Stable connection without breaks |
| Channel width | 40/80 MHz | Increases throughput capacity |
| AP Isolation | Disconnected. | Allows communication between devices |
What if the router does not support 5 GHz?
Solving Connection and Delay Problems
The most common problem is when the TV is simply not displayed in the list of available devices on the smartphone.The first thing to make sure that both gadgets are connected to the same network. Often users confuse the guest network with the main one or use different bands (2.4 and 5 GHz), which the router can display as different SSIDs, although modern routers often combine them under the same name.
If devices see each other but the connection is reset or the image is severely slowed down, try lowering the output resolution. In the streaming settings on your smartphone, you can sometimes choose 720p quality over 1080p or 4K. It also helps to close the background apps on the phone that can consume traffic or processor resources needed to encode the video stream.
In some cases, network resets are required. On a Xiaomi TV, you can do this through the Settings menu → Network → Network Reset. On a smartphone, a similar feature is in System → Settings Reset → Reset Wi-Fi, mobile Internet and Bluetooth. After this procedure, the device must be reconnected to Wi-Fi.
⚠️ Note: If after all the manipulations, screen duplication works with a strong delay, check whether the router is QoS (Quality of Service) mode with priority on other devices that can “clog” the channel by downloading torrents or updates.
Specifics of working with different smartphone manufacturers
Different smartphone manufacturers implement screen duplication in different ways, using their own shells and names. For example, on Samsung devices, the feature is called Smart View and has advanced aspect ratio settings. On Huawei and Honor smartphones, it is called Projection and often requires confirmation through the HiShare or Huawei Share app, which sometimes needs to be installed on the TV.
Xiaomi, Redmi and Poco smartphone owners can use the Broadcast function in the notification curtain. The MIUI or HyperOS shell has a convenient multimedia control panel where you can not only duplicate the screen, but also control the playback on TV. Activation sometimes requires you to turn on the Mi Share service in the connection settings.
As mentioned earlier, not all Xiaomi TVs have built-in AirPlay support out of the box (usually Android TV 9.0 or higher or special versions). If native support is not available, installing a receiver app on TV is a prerequisite for successful Apple app connectivity.
💡
Protocol compatibility (Miracast for Android/Windows and AirPlay for Apple) is a key factor in successful connectivity, so the choice of method depends on the ecosystem of your smartphone.
