HIGHlite Cine 260, 1080p 330
User Manual
Shifting the image
Ideally, the projector should be positioned perpendicular to the screen.
The normal position for the projector is at the centre of the screen. However, with
the zoom lenses, you can set the projector above or below the centre, or to one
side, and adjust the image using the
Lens shift
controls on the top of the projector
to maintain a geometrically correct image.
The maximum range available with no distortion is dependent on which zoom lens is
used. The tables below show the maximum range for images that fill the DMD. For
images which do not use the full height or width, extra shift may be possible, up to
the limit of the lens mount movement.

It is physically possible to shift the lens further than this, however there will be some
distortion of the image beyond the ranges specified above.
Notes
For more information on using
the Lens shift feature, see
section 4. Using the menus,
Using the control keys
.
If the lens is to be shifted in
two directions combined, the
maximum range is somewhat
less, as can be seen below.
