Geometry

Projector and/or screen placement — among other things — can cause geometric

distortion in the projected image.

To correct this, the DHD 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 3-23.

Figure 3-23. 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.
