Adjusting the Image
Geometry
Projector and/or screen placement — among other things — can cause geometric
distortion in the projected image.
To correct this, the Dimension Digital Controller provides precise, nine-point control
over the projected image geometry. Use these controls as (and only if) needed to
re-position the image corners, mid-points and center to eliminate “keystoning”
(mis-aligned corners) or “pincushion” distortion (mid-points not aligned with corners).
See Figure 3-28.
Figure 3-28. Keystone and Pincushion Distortion
“Keystoning” usually occurs when the projector is tilted relative to the screen.
“Pincushion” distortion can sometimes occur if the throw distance is very short and/or
the projector is equipped with an anamorphic lens.
