Adjusting Projected Image Position Using Shift
The Shift 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.
Shift is a unique system that provides lens shift while maintaining a much higher ANSI contrast
ratio than traditional lens shift systems.
Adjusting the vertical image position
The vertical image height can be adjusted between 50% and -10% (XGA) of offset position. 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 image position is at maximum. Please consult the Shift Range diagram
below for further clarification.
