Modern technology makes it possible to turn any Smart TV into a powerful multimedia center, and Xiaomi TVs are no exception. Users often wonder how to broadcast the contents of their smartphone screen on a large diagonal to comfortably view movies, photos or play games. The answer lies in the ability to wirelessly transfer data over a local Wi-Fi network, which is built into the shell of PatchWall or Android TV.
The main advantage of this approach is that there are no wires at all, which eliminates the need to pull HDMI cables across the room. However, to ensure that the connection works consistently and without delay, you need to comply with a number of technical requirements and properly configure both devices. In this article, we will discuss in detail all available methods, from built-in system functions to third-party applications.
Whether you have a Samsung, Honor, Realme or iPhone, the algorithm will be similar, although it has its own nuances in the interface. It is important to understand that the quality of the picture depends on the speed of the router and the distance between the devices.
Network requirements and device compatibility
The first and most critical condition for a successful broadcast is to have both devices on the same local network.This means that your smartphone and Xiaomi Mi TV must be connected to the same router. If you have a dual-band router that broadcasts 2.4 GHz and 5 GHz networks, make sure that both devices use the same frequency range to minimize latency.
Modern Xiaomi TVs support Miracast (for Android) and AirPlay 2 (for iOS), as well as the DLNA protocol for transmitting media. The built-in Wi-Fi module in a TV usually runs at 5 GHz, which provides high bandwidth for streaming video in 4K.
⚠️ Note: If your router is set up in guest network mode or customer isolation is enabled (AP Isolation, devices won't see each other. To properly work the screen broadcast function, you need to turn off the isolation in the router settings.
It’s also worth checking that both devices have a wireless module enabled. Sometimes the system can block detection if power saving mode is on. Make sure the TV software is updated to the latest version through the Settings menu → About TV → System Update.
Use of the built-in Screen Mirroring function
The easiest way to duplicate the screen is to use the native Screen Mirroring (or Wireless Monitor) feature. On Xiaomi TVs, this feature is often already active by default and waiting for a connection. You don't need to install additional apps if your smartphone is running Android.
To start the process on the TV remote control, find a button with a smartphone image or an icon "Mi Remote". By clicking on it, you will be taken to the signal source selection menu, where you need to select the option Wireless Monitor or Miracast.
On a smartphone, the action will depend on the model:
- 📱 Nana Xiaomi/Redmi/POCO: Open the notification curtain and select "Translation" or "Projection".
- 📱 On Samsung: the feature is called “Smart View” and is located in the Quick Settings Panel.
- 📱 Nana Huawei/Honor: This option is called a “projection” or “wireless projection".
- 📱 On other Android: Look for Translation, Cast, or Smart View in your connection settings.
Once the network is scanned, the phone will detect your Xiaomi TV. Click on its name in the list and the image will instantly appear on the big screen. Latency in this mode is minimal, allowing you to use the phone as a remote for games or presentations.
☑️ Checking before connection
Broadcasting via Google Home and Chromecast
Since Android TV is based on Google products, the most stable method is the use of Chromecast built-in technology.This method is ideal for transferring videos from YouTube, Netflix or Chrome apps, since it broadcasts not a screen, but a stream link, which reduces the load on the phone.
To manage this process, you will need the Google Home app, which can be downloaded from the Play Market. Once installed and logged in through your Google account, the app will automatically find all compatible devices on the network. Find your Xiaomi TV in the list and click on the Translate screen button.
The advantage of this method is that it supports high-resolution and Dolby Audio audio tracks, and you can control playback from your phone without fear that an incoming call will interrupt the movie, since the stream goes directly from the server to the TV.
| Method | Delay. | Quality. | Dependence on the phone |
|---|---|---|---|
| Miracast | Low. | Depends on the signal. | High (screen duplicated) |
| Chromecast | Minimum | Stable HD/4K | Low (remote only) |
| DLNA | No. | Original file | Medium (media only) |
💡
When using Chromecast, you can roll the app on your phone or even block it – the video on your TV will continue to play, saving you battery power.
Broadcast from iPhone and iPad (AirPlay)
Apple owners can take advantage of the built-in AirPlay feature, which is supported by many Xiaomi TV models. If your TV model does not have official AirPlay 2 support, it is not a problem - just install the AirScreen or ApowerMirror app from the app store on the TV.
The connection process is as simple as possible: open the Control Point on your iPhone (swipe down from the top right corner or bottom up on older models) and click on the Screen Replay icon (two rectangles).
When you first connect to your TV, you may have a confirmation code that you need to enter on your iPhone, which is designed to be safe, so that outsiders can't stream content to your screen without permission, and then pair it with high quality, with minimal compression.
⚠️ Note: To operate AirPlay in high quality (4K HDR) It requires a very stable 5GHz Wi-Fi signal. If the signal is weak, the system will automatically lower the resolution to 5GHz. 720p or 1080p, avoiding the jerking of the image.
Video and photo transfer via DLNA
If your goal is to show friends photos from your vacation or run a downloaded movie that is not supported by online services, the best protocol is DLNA. It allows you to transfer media files directly from your phone’s memory to the TV decoder, avoiding duplication of the system interface.
To implement this method, the phone must have a DLNA-enabled media player, such as a VLC for Android, MX Player or a standard gallery. Open the file you want, click the Translation button (usually looks like a rectangle with waves), and select a Xiaomi TV from the render list.
The TV will take the signal as an external source and open up the built-in player to play back, freeing up the smartphone's processor and allowing it to be used for other tasks, and supporting virtually all popular video and audio formats.

Solving Connection and Quality Problems
Despite the simplicity of the technology, users may face difficulties, and the most common problem is that the TV is not on the list of available devices, 90% of the time it is due to the fact that the devices are connected to different networks (for example, one to the main, another to the guest) or used the 2.4 GHz band instead of 5 GHz.
Another reason could be the blocking of ports by antivirus on your phone or the settings of the router firewall. Try temporarily turning off mobile internet on your smartphone, leaving only Wi-Fi so that the system does not try to prioritize cellular data.
If there is an image but no audio, check the audio output settings in the app from which the broadcast is coming. Sometimes the sound stays on the phone if you select Screen Only mode, not Media mode. Also make sure that the TV does not have Video Only mode.
- 🔄 Reboot the router and both devices – this solves most software failures.
- 📶 Get closer to the router to prevent loss of data packets.
- 🔌 Turn it off. VPN on the smartphone, as it changes the local IP-address and hide the device from the network.
💡
The stability of the connection over Wi-Fi depends on the absence of interference in the air and the loading of the channel by neighboring routers. In apartment buildings, it is better to use a wired connection or a dedicated 5 GHz band.
