• 📺 Screen duplication – The external device displays an exact copy of what you see on your phone (ideal for presentations or viewing photos).
• 🎮 Screen extension – the phone is used as a remote and only content is shown on the TV (e.g. video or game).
• 🔄 Backcasting is a rare mode where the phone acts as a receiver (for example, to output an image from a camera or other device).

On Xiaomi smartphones, the broadcast is implemented through several protocols:

• 📶 Miracast – wireless video transmission standard without a router (works on Wi-Fi Direct).
• 🌐 Google Cast (or Chromecast) – streaming via router, supports streaming content from apps (YouTube, Netflix).
• 🔌 HDMI — wired connection via an adapter (e.g, USB-C to HDMI).
