Positioning your projector 17
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
Refer to "Dimensions" on page 68 for the center of lens dimensions of this projector
before calculating the appropriate position.
MS535/MX535/MS535A
The screen aspect ratio is 4:3 and the projected picture is 4:3
For example, if your projector is MS535/MX535/MS535A and using a 120-inch screen, the
average projection distance is 5270 mm and with a vertical offset of 110 mm.
If your measured projection distance is 5.0 m (5000 mm), the closest match in the
"Projection distance (mm)" column is 5270 mm. Looking across this row shows that a 120''
(about 3.0 m) screen is required.
