Positioning the Projector

Before connecting the projector, you need to decide where to place it.
If the projector isn't already installed in the room you're using, you
can place it on a table in front of the screen. This lets you stand in the
front of the room, face the audience, and control the projector.
Ideally, you should place the projector between 26 to 48 inches (66 to
122 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.
