INSTALLATION AND SETUP
Figure 2.7. Maximum Vertical Offsets (ZOOM LENSES)
NOTES: 1) If you cannot raise or lower the image enough using
mechanical vertical offsets, try adjusting V-Position in the Size
and Position menu (see 3.6, Adjusting the Image). 2) If the image
becomes keystoned or exhibits uneven brightness, the projector
may simply be too high or low in relation to the screen.
3) Recommended offset ranges can be exceeded, however this may
affect image quality. 4) Simultaneous horizontal and vertical
offset limits the adjustment range of each.
THE HORIZONTAL POSITION of the image can be offset-that is, shifted left or right of lens center-by
turning the bottom screw on the front of the projector (the top screw if the projector is ceiling mounted). The
maximum horizontal offsets for the lenses designed for this projector is shown in Figure 2.8. For this projector,
this value expresses the maximum percentage of the image that can be projected to one side of the lens center
(roughly 80%, depending on the lens).
