Installation

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 3-21.
