14 Positioning your projector
Obtaining a preferred projected image size
The distance from the projector lens to the screen, the zoom setting, 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
For example, if you are using a 120-inch screen, the recommended projection distance is 3500
mm.
If your measured projection distance is 300 cm, the closest match in the
"Distance from screen
(mm)"
column is 2914 mm. Looking across this row shows that a 100'' (about 2.5 m) screen is
required. The projected image will be slightly higher/lower than the lens centerline with 125
mm vertical offset.
• *The vertical offset value is the vertical distance from the bottom edge of the image (when the projector
is placed 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.
