Broadcasting your smartphone screen to Xiaomi’s big TV opens up new possibilities, from watching high-resolution movies to showing presentations or running mobile games on a wide display. However, many users face difficulties in setting up a connection — especially when it comes to compatibility of devices of different brands or outdated models. In this article, we will discuss all the current ways of projecting the screen, including wireless technologies (Miracast, Wi-Fi, Google Cast) and wired solutions (HDMI, USB-C), and also explain how to avoid typical errors.
It’s important to understand that the way you connect depends on your Xiaomi TV model (e.g. Mi TV 4S, Mi TV Q1, Redmi Smart TV) and the Android version on your smartphone. So, Android TVs (e.g. Xiaomi Mi TV Stick or Mi Box) support more protocols than PatchWall models with a proprietary shell. We tested all methods on 2020-2026 devices and highlighted the only one-size-fits-fits-all method that works even on budget TVs without Smart features.
1. Wireless streaming via Miracast (for Xiaomi TVs on Android TV)
Miracast is a wireless screen standard built into most modern Xiaomi Android TVs (e.g. Mi TV A2 43" or Xiaomi TV Q2 55"), and does not require an internet connection, as it creates a direct connection between the phone and TV via Wi-Fi Direct.

- ⚡ Low latency – suitable for gaming (latency) ~30-50 ms).
- 🔋 Phone battery consumption: ~15-20% per hour.
- 🚫 Does not work on Xiaomi TVs with a proprietary PatchWall shell (e.g. Mi). TV 4A).
2.Using Google Cast (Chromecast) for PatchWall TVs
If your Xiaomi TV is powered by a PatchWall shell (such as the Mi TV 4X or Redmi Smart TV X), Miracast may not be available, and Google Cast technology integrated with apps like YouTube, Netflix or Google Photos will help.
