There may be some pincushion distortion even after the lens is

Note properly adjusted, especially at shorter throw distances. If this is the case, Runco recommends that you slightly over-scan the image into the screen frame area to mask the distortion.

3.Adjust the rotation of the Lens Transport Assembly so that the left and right sides of the image are an equal distance from their respective screen borders.

4.Tighten the Pivot Screw and the four mounting screws holding the transport to the Attachment Plate.

5.For optimum multiple aspect ratio performance, adjust the projector’s zoom so that a 1.85:1 aspect ratio movie is just masked by the top and bottom of the screen border when the anamorphic lens is not in front of the primary lens. This way 1.85:1, 16:9 and 2.35-2.4:1 aspect ratio movies are all presented to fill the screen at a constant height.

6.Remove the protective film from the front of the anamorphic lens.
