Obtaining A Preferred Projected Image Size - BenQ Home Entertainment Series User Manual

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 16:9 and the projected picture is in a 16:9 aspect ratio

Vertical Offset (A)*
• *The vertical offset value is the vertical distance from the bottom edge of the image (when the projector is on a
table, diagram on the left), or top edge of the image (when the projector is ceiling mounted, diagram on the right)
to the centerline of lens.
• Due to the lens optical characteristics, every projector has its vertical offset ratio. The vertical offset value
normally gets larger while the projection distance increases.
