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.
Suspending from the ceiling
A screen in a high location
Projector situated to the side so that the screen can be viewed sitting right in front of it
Projector situated on a shelf, etc.
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 dials can be used to position the image and is especially useful when using the projector in the
following locations. p.16
This is the height from the centre of the lens to the bottom of the
projection images. It can be changed by the vertical lens shift
setting.
If the projector is placed at an angle to
the screen, then the projected image will
be distorted.
