3.6 Projector shift and tilt range
Shift range
The lens can be shifted with respect to the DMD (P) which result 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 it's recommended to keep the shift values within the field of view (F)
as illustrated below. 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.

It is mechanical possible to shift outside the recommended field of view, but it will result in a decline
of image quality depending on the used lens and the zoom position of the used lens. Furthermore,
shifting too much in both directions will result in a blurred image corner.
Best image quality is projected in the On-Axis configuration.
Horizontal and vertical projector tilt ranges
The projector can be rotated and mounted at any angle.
