Projection Distance
The distance at which you place the projector from the screen determines the approximate size of the
image. The image size increases the farther the projector is from the screen, but can vary depending on
the zoom factor, aspect ratio, and other settings.
Use the tables here to determine approximately how far to place the projector from the screen based on
the size of the projected image. (Conversion figures may have been rounded up or down.)
