Adjusting the Height (Y): With the white field still on-screen, loosen the
Height/Y Adjustment T-Screws on either side of the lens. Then, slowly move the anamorphic
le
ns into place so that there are no shadows on the top or bottom of the screen:
When the height is properly set, tighten the Height Adjustment T-Scre
ws to secure the lens
in place.
Adjusting the Pitch (Angle): Next, angle the lens to even out
any top-to-bottom pincushion
distortion. To do this, loosen the Pitch Adjustment T-Screws (directly below the
Height/Y Adjustment T-Screws) on either side of the l
ens to allow it to pivot freely. Then,
adjust the anamorphic lens angle so that the projected image is rectangular:
The anamorphic lens will almost always be angled with respect to the projector; this is
no
rmal.
Once the proper lens angle has been set, firmly tighten the Pitch
Adjustment T-Screws to
secure the lens in place.
There may be some pincushion distortion even af
ter the lens is properly
adjusted, especially at shorter throw distances. If this is the case, Vidikron
recommends that you slightly over-scan the image into the screen frame
area to mask the distortion.
