Maximum shift range
The lens can be shifted with respect to the internal optics of the projector (DMD) which results in a shifted
image on the screen (Off-Axis). A 100% shift means that the centre point of the projected image is shifted by
half the screen size. In other words, the centre point of the projected image falls together with the outline of the
image in an On-Axis projection. Due to mechanical and optical limitations the shift range is limited as well.
All lenses have a shift range of 50% up, 50% down, 30% left, and 30% right. This range is valid for all throw
ratios. Within these shift ranges the projector and lens perform excellently. Configuring the projector outside
these shift ranges will result in a slight decline of image quality.
The Lens Holder of the projector can be mounted in a lower position so that the lens can be shifted 100%
down (0% up).
