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 whitelevels, are
typically used in conjunction with mechanical lens blinders (optional), which are
installed on the front of the projector and which primarily affect blacklevels
.
NOTES: 1) 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.
2) See also 3.10, Using Multiple Projectors .
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 3 pre-defined color
performance settings identified at right
(default=Max Drives), or colors can be
driven on the basis of color temperature
(Figure 3.21). 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.
DEFINING “USER” COLOR GAMUTS:
In some cases, you may find that none of the pre-
defined “Select Color Adjustment” options exactly suit your needs. For example, you
may require a unique color gamut (range) for a single projector or application, or you
may need to precisely match colors across multiple adjacent displays. In such cases,
use the
Color Adjustments by X,Y or Color Saturation submenu to define the precise
Figure 3.21. Color Gamut Choices
