Adjusting the Screen Image
12
The lens shift function can be used to adjust the position of projected images when the projector has been set
up in places such as the following.
When the projector is suspended from a ceiling
When the screen is higher than the projector
When the projector is at an angle to the screen so that people can sit directly in front to view the screen
When the projector is on top of a desk or similar
The lens shift function can move the lens horizontally and vertically to adjust the image position without
causing keystone distortion. Use the two lens shift dials to adjust the position of the projected images.
* At the time of shipment from the factory, the vertical lens shift position is set to the lowest position, so
move it to the center position before carrying out adjustment.
* The dotted lines indicate the projection range from the lens center position.
* The lens cannot be shifted to the maximum vertical and horizontal positions at the same time.
Adjustment procedure
Turn the two lens shift dials to adjust.
When the lens shift dial is turned, a point of
resistance will be felt. This indicates the
approximate center point for the range of
adjustment. In addition, if the lens shift dial
becomes hard to turn further and the image
position stops changing, no further adjustment is
possible.
Projection image position adjustment (Lens shift)
If the projected images are tilted horizontally, use the left and right front adjustable feet to
adjust the projector so that it is level.
