Adjusting Projected Image Position
Using PureShift
The PureShift feature provides a lens shift function that can be
used to adjust the position of the projected image either horizontally
or vertically within the range detailed below. PureShift is a unique
system that provides lens shift while maintaining a much higher ANSI
contrast ratio than traditional lens shift system.
Adjusting the vertical image position
The minimum vertical image offset is fixed at 5% of the image
height above the centre of the projector lens. This can not be
changed. The vertical image height can be adjusted between 5%
and 30% of the image height. Note that the maximum vertical
image height adjustment can be limited by the horizontal image
position. For example it is not possible to achieve the maximum
vertical image position height detailed above if the horizontal im-
age position is at maximum. Please consult the PureShift Range
diagram below for further clarification.
