COLOR SATURATION:

this submenu if you do not
have specific color
coordinates in mind and will
simply judge color
performance by eye or
meter. Like the Color
Adjustment by X, Y
submenu, each color control
actually defines new x/y
coordinates for that color
and changes its hue—it is
just a different interface.
Figure 3.24.
Adjust the hue of each
primary color (red, green,
blue, and white) by using more or less of it in relation to the other colors.
NOTE: A Color Saturation adjustment defines the corresponding x/y coordinates
shown in the Color Adjustment by X, Y submenu. These x/y coordinates will remain
stable for this User gamut until they are changed again via either menu. Values
displayed in the Color Saturation menu, however, will likely fluctuate as you use the
projector, and will be different when you return to this menu at some point in the
future. These floating changes do not affect the x/y coordinates or gamut.

Black Level Blending

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.
