Black Level Blending — SUBMENU
Black Level Blending is a feature that eliminates the differences between black levels
when edge blending multiple projectors. The Black Level Blending submenu provides
many controls to allow the edges of adjacent images to be smoothly overlapped
creating a “seamless” image. Black Level Blending provides a simple solution for
uneven black levels, without the need for external hardware, by matching up black
level hues with a “target area” hue (the intersection of the center lines), and adjusting
the overlaps (edges) surrounding the target area.
The use of Black Level Blending feature and the use of Christie TWIST module are
mutually exclusive. On a WU model, Keystone is only available when Christie
TWIST is in use. If Christie TWIST is installed and Black Level Blending is desired:
1. Disable use of warps or 2D Keystone.
2. Enable edge blending; if not enabled.
3. Enable Black Level Blending.
4. Power down the projector then power up again.
Adjustments can now be made to black level controls.
To restore the use of Christie TWIST:
1. Disable black blending.
2. Power cycle the projector.
3. Begin using the TWIST controls.
NOTES: 1) Refer to section 3.10, Using Multiple Projectors for additional
information. 2) There is a centerline (both horizontal and vertical) in the Black Level
Blending test pattern. The intersection of these lines is the true center of the
projector’s display area. 3) Adjust white levels before adjusting black levels. 4)
Blinders are recommended for fixed installations.

Intelligent Lens System (ILS
) — SUBMENU
ILS provides the ability to recall focus and zoom settings specific to each source
input. Custom lens settings you’ve chosen for any source will be quickly and
accurately applied when you select a source that has already been calibrated. Place a
checkmark in the checkbox to enable ILS. If no calibration has previously been
done you may be prompted to do a full calibration. If a motion calibration has been
done, you will be prompted to complete a reference calibration. If both calibrations
have been done, the checkbox will be checked and ILS enabled. If ILS is enabled,
a reference calibration will be done on power up and the lens will return to the saved
position of the source that is active at the time of power up or to the position the lens
was located when it was powered on. Further adjustments to the zoom, focus and
position will be automatically saved for source the selected source. If you switch to a
source with different lens settings and switch back, the lens will automatically move
to your saved settings upon return. Other sources can be used without using ILS .
