14 Positioning your projector
Obtaining a preferred projected image size
The distance from the projector lens to the screen, the zoom setting (if available), and the video format
each factors in the projected image size.
Projection dimensions
• The screen aspect ratio is 16:10 and the projected picture is in a 16:10 aspect ratio
For example, if you are using a 120-inch screen, the recommended projection distance in the "Average"
column is 4171 mm.
If your measured projection distance is 4500 mm, the closest match in the "Average" column is 4519
mm. Looking across this row shows that a 130'' (about 3.3 m) screen is required.
