ELI5: How does a video projector cast dark/black light?

I feel as though I'm on par or better with intelligence, I realize how easy it would be because of contrast if we are talking about spots of darkness when a movie plays. But I'm in a room with some lighting, projector on, no connections, and a bright wall except for the whole projecting frame, black/dark grey saying, "no connection".
