Obtaining a preferred projected image size
The projected image size is determined by the distance from the projector lens to the screen, and the video format. The data in the table below is
based on a normal projection method and not the result of adjusting the projection angle (1-15 degrees).
Projection dimensions
Use the illustration and tables below to help you determine the projection distance.
