Horizontal Lens 

Shift Lever

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.

Vertical Lens 

Shift Lever

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.
