Note

These sizes are ± 1%. This is due to variations in the manufacture of the lens. If you are close to one of the endpoints you should verify with your unit that the image is the proper size at the proper distance.

The image can be shifted up or down without distortion (keystoning) by turning the Image Shift Control knob on the top of the projector.
