Adjusting the Image
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 3-13.
