Projection distance for 4:3 aspect ratio screen
(ET-D75LE1/D75LE2/D75LE3)
Unit: feet
Unit: millimeters
•
The value for L (distance to screen) varies slightly depending on the zoom lens characteristics.
•
At the shortest projection distance, the zoom lens characteristics may cause slight image distortion.
•
When vertical keystone correction is used, the image is corrected in the direction that reduces its projected size.
NOTE: When the fixed-focus lens is mounted, the optical lens shift function cannot be used.
