for reference. After the projector is roughly positioned, picture size and vertical picture positioning can be finely
adjusted with the powered zoom lens and lens shifting mechanism.

SH : Height of the image
SW : Image width
H : Vertical distance between the lens centre
level and the bottom edge of the projected
image
For PT-D7700E: H = 0 to SH
For PT-DW7000E: H = -0.18 x SH to 1.18 x SH
