How it works

A real extra screen, not a mirror.

macOS thinks you plugged in a monitor. It shows up in System Settings → Displays, and only what you put on it goes to the TV.

Your Mac grows a new screen

A 1280×720 display appears, ready for windows.

CGVirtualDisplay

Only that screen is filmed

Your main screen stays private.
