Adjusting the projection size
Lens shift adjustment
When the projector is further away from the screen, the projection image size are larger.
While referring to the table below, position the projector so that the images are projected onto the
screen at the optimum size.
The values should be used as a guide for setting up the projector.
When the projector is suspended from the ceiling
When the height of the projector does not match with that of the screen
When the projector is set up to the side so that the screen can be viewed sitting right in front of it
When positioning an image using the lens shift dial, hardly any deterioration of the image occurs because the lens
shift correction is adjusted optically. However, for optimal image quality the lens shift function should not be used.
The lens shift can be used to position the image and the feature is especially useful under the following conditions.

Set up so that the projector is parallel to
the screen. If the projector is set up at
an angle to the screen, distortion of the
images will occur.
