Obtaining a preferred projected image size
The distance from the projector lens to the screen, the zoom setting, and the video format each factors in the projected image size. BenQ has provided separate tables of dimensions for both 16:9 and 4:3 screen ratios to assist you in determining the ideal location for your projector.
1.Determine the aspect ratio of your screen, (16:9 or 4:3)?
2.Select the Screen Size you desire from the 16:9 ratio screen dimension table or 4:3 ratio screen dimension table below, according to which screen aspect you have. Install the projector at a distance from the screen corresponding to between the Min. and Max. Projection Distance values in the table.
3.Decide the exact height of your projector.
