4. 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

normal.

5. When the height and angle are properly set, tighten the Height/Pitch Adjustment

Screws to secure the lens in place.

Movable Anamorphic Lens Attach the movable anamorphic lens to the bracket using the plastic knobs supplied with

the lens. See Figure 3-17.

Adjusting the Lens Position:

1. Adjust the vertical position and tilt of the lens so that the projector beam is passing

through the center of the lens and any residual pincushion distortion is about the

same at the top and bottom of the image. This typically results in the anamorphic lens

being below the center of the primary lens and tilted slightly downward.

There may be some pincushion distortion even after the lens is

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.
