In the Configuration menu, select
the Geometry and Color submenu
when you need to modify overall
color performance and/or image
geometry for all sources.
Test Pattern
Choose the desired internal test
pattern, or select OFF to turn off a
test pattern. Alternatively, use the
key for cycling through test patterns.
Test
Keystone
NOTE: If the optional ChristieTWIST module is installed, this option is Keystone
and Warping, and activates a submenu for defining custom image shapes. Please
refer to documentation included with your Christie TWIST module.
Use to correct a keystoned image shape in which both sides of your image are
inclined toward the top or bottom edge. Keystone is typically caused by tilting the
projector in relation to the screen, so that the lens surface and screen are no longer
parallel to each other.
Brightness Uniformity
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.
NOTE: See also 3.11, Using Multiple Projectors for the complete step-by-step
procedure for achieving uniform brightness in adjacent displays.
— SUBMENU
Edge Blending
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. NOTE:
There is a center line (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.
NOTE: See also 3.11, Using Multiple Projectors.
