Modern Xiaomi TVs, which run on Android TV or PatchWall, offer ample opportunities for multimedia content. However, many users have difficulty in trying to display images from a smartphone or laptop to a large screen without using cables. Wireless data transfer allows you to enjoy movies, photos and games in high quality, eliminating the need to search for adapters.
In this article, we will take a look at all the ways you can connect, from standard system functions to third-party apps, how to activate Miracast mode, configure live streaming via Google Chromecast, and even connect Apple devices via AirPlay. Understanding how these protocols work will help you avoid delays and desynchronization of sound.
Before you start setting up, make sure your router supports 5GHz Wi-Fi standards, as this greatly improves the stability of the video stream. It is also worth checking whether the TV firmware is updated to the latest version, since developers regularly make improvements to wireless modules.
Preparation of equipment and network
The first and most important condition for successful wireless broadcasting is to have all devices on the same local network. Your smartphone (whether Android or iOS) and Xiaomi TV must be connected to the same router. If you have a dual-band router, make sure that both devices use the same frequency, preferably 5 GHz, to ensure sufficient channel bandwidth.
Check the date and time settings on both devices. Time zone mismatch or different times can lead to authorization errors when trying to connect via DLNA or Cast. This is an often overlooked nuance that causes problems for beginners, although solved by elementary synchronization over the Internet.
For stable operation, it is recommended to disable the client isolation function (AP Isolation) on the router if it is activated, this security setting prevents devices within the network from communicating with each other, making it impossible for the phone to detect the TV.
⚠️ Note: If your router is giving away two networks with the same name (2.4 GHz and 5 GHz) and uses Smart Connect, try temporarily splitting them or forcefully switching your TV to 5 GHz to reduce latency.
Using the built-in Cast feature on Android
The most common way to transmit images is to use Google Cast technology, which is built into most Android smartphones. On Xiaomi Mi TVs, this module is also active by default. You don't need to install additional apps if both devices are running the Google ecosystem.
To start the broadcast, lower the notification curtain on your smartphone and look for the Broadcast or Cast icon (the rectangle with the waves in the corner). Once you click, the system will start looking for available devices. Your TV should appear on the list, often labeled as Android TV or a TV model, such as MI TV 4S.
- 📱 Make sure your phone is Bluetooth enabled and geolocated, they help in device detection.
- 📺 On some TV models, you need to confirm the connection by accepting the request on the TV screen.
- 🔄 If the device is not found, try restarting the Google Home app or the TV itself.
Once you've successfully connected, your smartphone's screen will appear on your TV. It's important to understand that Mirror doesn't sleep and your battery is used up faster. You'd better use the Cast button inside the apps themselves, like YouTube or Netflix, so you can control playback from your phone without spending your resources encoding videos.
💡
Use the horizontal orientation of the phone screen before connecting so that the image immediately occupies the entire TV screen without black fields.
Streaming from iPhone and iPad via AirPlay
Owners of Apple appliances may face the question of compatibility, as the iOS ecosystem uses its AirPlay protocol. Fortunately, modern Xiaomi TVs with Android TVs often have built-in AirPlay 2 support. If your TV model is released after 2019, chances are that feature is already present in the system.
To check the availability of the feature, go to your TV settings. You need to find the section related to connecting Apple devices. The path may vary depending on the version of the PatchWall shell, but it's usually hidden in the app menu or network settings. If there's no built-in support, you can install the AirScreen app from the Google Play Store on your TV.
The process of connecting to the iPhone is as simple as possible:
- Open the Control Point on your smartphone (swipe down from the upper right corner or bottom up for models with a button).
- Press the screen repeat button (two rectangles).
- Choose your Xiaomi TV from the list.
⚠️ Note: When you first connect your iPhone to your TV, a 4-digit code may appear on your TV screen. Enter it on your smartphone to confirm pairing.
AirPlay transmissions are usually better than Miracast, thanks to better video stream compression, but for games this method may not be suitable due to input lag, which can be anywhere from 100 to 300 ms. For watching movies, this is completely invisible, but in dynamic shooters you can feel the dissynchrone.
Miracast (Wireless Monitor)
Miracast is the standard for mirroring screens on Android and Windows devices. Unlike Chromecast, it creates a direct Wi-Fi connection between devices, allowing you to stream an image even without Internet access, as long as the router supports Wi-Fi Direct mode.
On Xiaomi TVs, the feature is often called Wireless Monitor or Wireless Display. To activate signal reception, you need to run the corresponding app on the TV. It can be located in the Apps folder or displayed on the top menu. After you start, the screen will wait for the connection.
On a Xiaomi smartphone (MIUI) or other Android device:
- 📡 Go to the settings -> Connection and sharing -> Broadcasting.
- 🔍 Turn on the switch and wait for your TV name to appear.
- 📲 Click on the TV name to start mirroring.
For Windows 10 and 11 users, the process is even easier. Press the Win + K keyboard. On the right side of the screen, you'll see the Connect panel where you want to select your TV. The system will automatically install the virtual display drivers.

Comparison of connection methods
The right method depends on your goals: whether you want to just show photos to friends, play a mobile game on a big screen or watch a movie in 4K. Each protocol has its own technical features, advantages and disadvantages.
The table below compares the main features of the available technologies for Xiaomi TVs:
| Characteristics | Google Cast | Miracast | AirPlay 2 |
|---|---|---|---|
| Stability | Tall. | Medium | Tall. |
| Delay (Latency) | Low (in annexes) | Medium/High | Low. |
| Image quality | Up to 4K HDR | Depends on the signal. | Up to 4K HDR |
| Battery consumption | Minimum | High-pitched | Medium. |
As you can see from the table, the best way to view content from the Internet (YouTube, online cinemas) is to use the native Cast function inside apps, which broadcasts not the phone screen, but a link to the video stream that the TV plays itself, which frees the smartphone and provides the best quality.

Solution and optimization
Even with the right setup, there can be situations where the TV can't see the phone or the connection is constantly cut off. Often the problem lies in the router settings. Make sure you don't have the access point isolation that I mentioned earlier. Also try changing the Wi-Fi channel in the router settings to a less busy one, such as 1, 6 or 11 for 2.4 GHz.
If you use third-party broadcast apps like Web Video Caster or AllCast, make sure they are given all the necessary permissions on the Android system.Blocking background activity can cause the broadcast to stop once you turn off the smartphone screen.
In some cases, network resets help. On a Xiaomi TV, you can do this through the Settings menu -> About -> Reset. Don't worry, your apps and accounts will stay in place if you choose to reset only network settings, however, on some firmwares only a full reset is available.
⚠️ Note: When you completely reset your TV, all installed apps and logins will be deleted. Use this method only if other methods have not helped.
💡
The stability of wireless broadcasting is 90% dependent on the quality of the Wi-Fi signal and the absence of interference in the air, not on the power of the TV itself.
