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 hori-
zontally 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 verti-
cal 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 image position is at maximum. Please consult the
PureShift Range diagram below for further clarification.
