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 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.

WARP SHARPNESS: Adjust as desired to soften or sharpen the overall image, similar to a Detail adjustment.

WARP LATENCY: Set the percentage of frame delay (default = 50.0) desired for displaying incoming data. A higher or lower setting will typically be needed with significant warps, ensuring that the entire image appears. Warp latency also provides a means of synchronizing one display with adjacent displays or other equipment such as audio.

NOTE: If a ChristieTWIST™ module is installed, the Edge Blending menu controls are expanded to include user-defined blends appropriate for a warped image. The new blend ranges are 0-80 for side blends, and 0-60 for top or bottom blends. If no warping is currently applied but you still need to use edge blending for a tiled wall, select “Standard”.
