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 3-27.
