The D P2K -20C projector is equipped with a motorized lens shift functionality and a moto rized zoom & focus functionality.
Maximum shift range
The lens can be shifted with respect to the DMD which result in a shifted image on the screen ( Off-Axis). A 100% shift means that
the centre point of the projec ted image is shifted by half the s creen size. In other words , the centre point of the projected image falls
together with the outline of the image in an O n-Axis projection. Du e to mechanica l an optical limitations the shift range is limited as
well.
All DC2K lenses have a shift range of 50% up/down a nd 15% left/right. This range is valid for all throw ratios. O nly the 0.98" DC2K
