Position the projector on a flat surface at a right angle to the screen. The
projector must be at least 4.9 feet (1.5m) from the projection screen.
•
Position the projector within 10 feet (3m) of your power source and within 6
feet (1.8m) of your video device (unless you purchase extension cables). To

The image exits the projector at a given angle. IN1110a image offset is 115%;
IN1112a image offset is 112.4%. This means that if you have an image 10’
high, the bottom of the image will be 1.5' (IN1110a) and 1.24' (IN1112a) above
the center of the lens.
