Adjusting Projected Image Position Using Shift
Note:
Suggest to loosen the screw before lens
shift adjustment and tighten up after
finished adjustment.
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 110% and -30% 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.
