Positioning the Projector

The projector lens should be between 18 to 30 inches (47 to 76 cm)
from the screen. Use the illustrations and tables below to help you
determine approximately how far to place it based on the screen size
you're using and the aspect ratio of the image. Image size can vary
depending on how you adjust the zoom and other settings.
You can also use the Image Size Calculator on the Epson website.
