Installing the Projector

Projection Distance and Screen Size

This projector uses 1.3x manual zoom lens for projection.

The range of projection while retaining 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 30)

4:3 and 16:9 Screen

 

 

 

16:9 aspect-ratio picture is projected based

Screen

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.
