Notes: 1) “Factory” refers to the throw distance used at the factory for optical setup and testing.
2)All diagonal screen sizes are based on a 4:3 aspect ratio. “W” in the throw distance formula represents horizontal screen width. All dimensions are in inches.
3)Calculated values are for reference only. It is good practice to simulate the setup to determine the necessary throw distance.
