Types of Projectors

• Long Throw (Ratio 2.0+): Installed in the back of large halls or cinemas.
• Standard Throw (Ratio 1.3 - 2.0): Most home theater projectors. Placed behind the seating area or on the ceiling.
• Short Throw (Ratio 0.4 - 1.0): Placed on a coffee table or ceiling closer to the screen.
• Ultra Short Throw (Ratio < 0.4): Sits directly below the screen on a TV stand (Laser TVs).
