Displaying and Adjusting the Image
Positioning the Projector
If the projector isn’t already installed in the room you’re using, you’ll
probably want to place it on a table in front of the screen. This lets
you stand in the front of the room, face the audience, and remain
close enough to the equipment to be able to control it. Try to leave as
much space as possible between the projector and the screen to get a
good-size image.
Use the illustrations and tables below to help you determine
placement. Image size increases with distance, but can vary depending
on how you position the zoom ring and whether you’ve adjusted the
image with other settings.
You can also use the Image Size Calculator on the Epson website.

note
You can mount the projector
on the ceiling, or place it
behind a translucent screen
for rear projection. See
page 151 for details.
