Modern multimedia systems make it easy to stream content from mobile devices to a big screen, and Miracast technology, built into the MIUI TV interface, makes this process incredibly simple. You don't need additional cables or complicated adapters if your smart TV and smartphone are on the same network. This gives you access to high-definition movies, games, and presentations right from the palm of your hand.
However, despite the apparent simplicity, users often encounter signal delays or the inability to locate the device. In this article, we'll cover all the nuances of setup, from basic steps to solving complex data protocol compatibility issues. You'll learn how to control your smartphone screen with a remote and enjoy content without restrictions.
Wireless Broadcasting Technologies: Which One to Choose?
Before you begin setting up, it is important to understand that video transmission protocols The standards vary depending on your gadget's operating system. Xiaomi TVs typically support multiple standards simultaneously, ensuring cross-platform compatibility. The main players here are Miracast for Android and AirPlay for Apple devices.
Miracast technology creates a direct Wi-Fi connection between devices, transmitting images in real time without compression, which is critical for image quality. DLNA, on the other hand, only allows you to stream media files, not the entire screen. The choice of method depends on your goals: sharing photos with friends or playing a game on a larger screen.
- 📱 Miracast — a standard for mirroring Android screens to Android TV.
- 🍏 AirPlay 2 — Native support for iPhone and iPad in new Mi TV models.
- 🌐 Chromecast built-in — allows you to "cast" content from YouTube or Netflix apps directly.
It is worth noting that Xiaomi Mi TV Stick and built-in Smart TVs may have different firmware versions, which can affect connection stability. If one technology is intermittent, it might be worth trying an alternative data transfer option.
Preparatory stage: network setup
The foundation for the stable operation of any wireless system is a properly organized local network. Both devices—the smartphone and the TV—must be connected to the same routerA common mistake is using a guest Wi-Fi network or different frequencies if the router doesn't combine them into a single subnet.
It's recommended to use the 5 GHz band for heavy video streaming, as it's less congested and provides higher throughput. If your router broadcasts 2.4 GHz and 5 GHz networks under different SSIDs, make sure your devices are connected to one of them, preferably the faster one.
⚠️ Important: If AP Isolation is enabled on your router, devices will not be able to "see" each other. Check your router's security settings and disable this feature for your home network.
Also, before starting the procedure, make sure that the module is enabled on both devices. Wi-Fi and activated Bluetooth, which is often used for the initial handshake between devices. Restarting the router before configuration will help clear the connection cache and avoid IP address conflicts.
☑️ Network readiness check
Instructions: Connecting Android via Miracast
For Android smartphone owners, connecting to a Xiaomi TV typically doesn't require installing any additional software, as the feature is built into the system. Depending on the version of MIUI or stock Android, the function name may differ, but the operating principle is the same.

Stream from iPhone and iPad (AirPlay)
Apple device owners can use the native "Screen Mirroring" feature, as modern Xiaomi TVs support the AirPlay 2 protocol. This ensures high picture quality and minimal latency, which is essential for watching fast-paced video.
The process is as simple as possible: just call Control center on your iOS device and tap the corresponding icon. The TV must be turned on and in Smart TV mode, preferably with a signal-receiving app running if automatic detection fails.

Frequently Asked Questions (FAQ)
Is it possible to connect a phone to a Xiaomi TV without the Internet?
Yes, you can. Miracast and Wi-Fi Direct technologies create a direct connection between devices without requiring an external network. The main thing is that the Wi-Fi modules on both devices are active.
Why is there sound but no picture when streaming video from a phone?
This may be due to DRM content protection. Some streaming services block screen mirroring, requiring the use of a built-in TV app or Chromecast.
Does phone connection affect internet speed?
Using Miracast doesn't consume internet access, as the traffic is transmitted locally. However, the Wi-Fi channel itself may become overloaded, which could theoretically reduce speeds for other devices on the network.
How do I turn off the broadcast?
The easiest way is to press the "Stop" button in the streaming menu on your smartphone, or simply turn off the phone's screen if you're using mirroring mode. You can also switch the input source on your TV.
