• 2D Keystone: Move 4 corners of the image to correct for a keystoned image and/or to create an

unusual 4-sided image exhibiting perspective or distortion. See 2D Keystone, below.

• User 1-10: Note: The user-defined options are titled User 1-10 by default; they can be changed using

the ChristieTWIST™ Software. Apply a custom image shape or twist that has been defined in the

ChristieTWIST™ PC application and downloaded to projector memory, typically creating one or

more “squeezed” or stretched areas in the display. If no custom warps have been created, the User

options will have no effect.

2D KEYSTONE

Move one or more corner points

as desired for your application.

Traditionally, keystoning

adjustments simply correct an

image in which opposing sides

are inclined away from each

other (caused by tilting the

projector in relation to the

screen). If the lens surface is

parallel to the screen and settings

are 50.0, the image should appear

rectangular. Alternatively, move

the corner points as desired to

create a specific 4-sided image in

which corners are up to 25%

closer to the center of the image,

or which are cropped off.

WARP PRE-FILTER

HORIZONTAL: Adjust as

desired to smooth or sharpen

side-to-side clarity in a warped

image. An increase will appear to

blur horizontal lines.

WARP PRE-FILTER VERTICAL: Adjust as desired to smooth or sharpen top-to-bottom clarity in a

warped image. An increase will appear to blur vertical lines.
