Adjusting The Vertical Image Position - Optoma EX785 Manual

The PureShift 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.
PureShift 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 100% and -10%
for XGA, 105% and -15% for WXGA of image height. 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
PureShift Range diagram below for further clarification.
