Brightness Uniformity
— SUBMENU
Brightness Uniformity
provides further refinement of displays already matched for
their primary colors and overall light output. Use Brightness Uniformity to create an
exceptionally smooth image in which no area appears brighter and/or more red, green
or blue than another. In the
Brightness Uniformity
menu, enable the “Uniformity
Enable” checkbox to access a multitude of adjustments for critical color light output
control in specific areas throughout the image. Your settings apply as long as the
“Uniformity Enable” checkbox is enabled and you are using a “User” color
temperature defined by the Brightness Uniformity controls. To disable the Brightness
Uniformity function, delete the “Uniformity Enable” checkmark.
NOTES: 1) See also
3.10, Using Multiple Projectors
for the complete step-by-step
procedure for achieving uniform brightness in adjacent displays. 2) If Christie TWIST
module is installed, the enable checkbox changes to a list giving the option to choose
from several different uniformity maps. Please refer to documentation included with
your Christie TWIST module.
Edge Blending
— SUBMENU
The
Edge Blending
submenu provides a range of controls for smoothing together the
overlapping bright edges of multiple adjacent projected images to create a single
larger “seamless” image. These controls, which primarily affect white levels, are
typically used in conjunction with mechanical lens blinders (optional), which are
installed on the front of the projector and which primarily affect black levels. There is
a centerline (both horizontal and vertical) in the Edge Blending test pattern. The
intersection of these lines is the true center of the projector’s display area.

Color Adjustments by X/Y, and Color Saturation —
SUBMENUS
NOTES: 1) For defining or changing a User 1, 2, 3, or 4 color performance or
“gamut”. Sometimes known as Comprehensive Color Adjustment™. 2) Factory-
defined primary color levels, which ensure a specific color performance from
projector-to-projector, can be calibrated in the Service menu only. If you suspect
alteration of these defaults, the factory settings can be recovered with selection of
“Reset to Factory Defaults?”
in the Color Primary Settings submenu accessed via
the Service menu (password-protected).
From the factory, the projector can utilize
any of the three pre-defined color
performance settings identified at right
(default=Max Drives), or colors can be
driven on the basis of color temperature.
For most applications, one of these gamuts
will produce accurate and realistic colors
from a variety of sources. They can be
applied at any time in the
Advanced Image
Settings
menu (“Select Color
Adjustment”), and are not adjustable.
