Cancelling Brightness Uniformity
If you do not want to use or apply Brightness Uniformity settings, delete the
checkmark from the "Uniformity Enable" checkbox at the top of the Brightness
Uniformity menu.
Edge Blending
Christie Edge Blending is an innovative set of software functions that can quickly and
easily blend white levels along the edges of multiple adjacent projected images to
create a single seamless larger image.
What is a Blend?
In simple terms, a blend appears as a gradient strip
along an edge of a projected image. It is darkest along
the extreme edge of the image, and lightens nearer to
the rest of the image (see right).
How Are Blends Used?
In multiple-projector walls, complementary blends between neighboring images can
compensate for the extra "brightness" or intensity where these edges overlap. By
controlling blend width and other properties, you can achieve uniformity across the
group of images. Visible overlaps will disappear:

For best results, use the same projector model and type throughout your display wall.
In addition, avoid high-gain screens whenever possible—the optical performance of
such screens demands minimal image offset, thus projectors must be located very
close to one another.
Edge blending software controls are located in the two-page Edge Blending
submenu—access via Configuration menu, then go to the Geometry and Color menu
and select Edge Blending. The More option opens the second page of the Edge
Blending submenu.

Main Functions

Use Edge Blending controls to set the precise width, shape and midpoint you need to
blend overlapping edges together smoothly.
