013-100149-02 Rev. 1 (01/07) Christie DS+60/DW30/Matrix 3000 User’s Manual 3-41
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”.
Keystone
This option is available when the ChristieTWIST
™
module is not installed.
