Adjusting Projected Image Position Using Lens Shift
The Lens 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.
Note:
Do not rotate lens shift knob further under click sound and lightly press the knob to rotate back.
Adjusting the vertical image position
The vertical image height can be adjusted between 55% and -15% 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.
