Projector Placement

Standard throw projectors need 15.0-20.0 feet from the screen. Consider a short-throw projector if space is limited.

🎬

Screen Selection

For a 120" setup, invest in a fixed-frame screen for the flattest surface. ALR (Ambient Light Rejecting) screens help if you can't fully darken the room.
