Runco VX-2000d manual Adjusting the Lens Height Y

Installation

Adjusting the Lens Height (Y):

1.Project a white field on the screen.

2.Ensure that the four Height (Y) Adjustment Screws are loose enough to allow vertical movement of the lens assembly.

3.Slowly move the anamorphic lens into place so that there are no shadows on the top or bottom of the screen:

Too Low

Correct position

Too High

4.When the height is properly set, tighten the Height Adjustment Screws 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 Screws on either side of the lens to allow it to pivot freely. Then, adjust the anamorphic lens angle so that the projected image is rectangular:

Correct Lens Angle

Incorrect Lens Angle

The anamorphic lens will almost always be angled with respect to the projector; this is normal. Once the proper lens angle has been set, firmly tighten the Pitch Adjustment Screws to secure the lens in place.

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.
