Vertical Lens Shift
The lens-shift feature will vertically offset the picture from 1¼ in. (30 mm) up to 4 ½ in. (117 mm)
depending on the projector-to-screen distance and size of the projected image. This adjustment is
typically used with wall mount applications as a fine-adjustment to the vertical position of the projected
image. Turn the adjustment screw to vertically raise or lower the physical position of the lens. Refer to
the chart above for the offset values.
Note: The Lens-Shift adjustment screw does not adjust or change any keystone properties.
