Evaluate for distance by image size
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 76
calculating the appropriate position.
*** "A" is based on maximum lens shift offset position 55%
LU9255
The screen aspect ratio is 16:10 and the projected picture is 16:10.
Note:
To optimize the projection quality, we suggest to project images in an area without grayscale.
