Projection Distance and Screen Size
• This projector uses 1.3x manual zoom lens for projection.
• The range of projection for good focus is approximately 1.6m to approximately 12m when the aspect ratio of the screen is 4:3.
Install the projector within this range.
• If the KEYSTONE is adjusted, the screen becomes smaller. ( ☞ page 29)

4:3 and 16:9 Screen
16:9 aspect-ratio picture is projected based
on the width of the range in which a 4:3 as-
pect-ratio picture is projected. The diagonal
length of a 16:9 aspect-ratio screen is about
91.8% that of a 4:3 aspect-ratio screen.
