 Blend Midpoint determines the white
level at the blend midpoint (the point
equidistant between the beginning and
end of the blend). Increasing the Blend
Midpoint setting creates a blend that
appears brighter than the rest of the
image. Decreasing the Blend Midpoint
setting creates a blend that is darker than
the rest of the image. A setting of 50
means the midpoint is approximately
50% black—for best results in most
applications, keep fairly close to this
default.

Show Blending Overlap turns your
defined blend width area to solid gray so
that, if needed, simply overlapping the
gray bars can seamlessly align two
adjacent images. Toggle the Show
Blending Overlap off to reactivate the
blend effect.
NOTE: Blending Overlap appears as
Reserved when Christie TWIST is
installed.
Other Functions
For convenience, the Edge Blending
submenu also includes related options for
enabling a specific color and/or test pattern,
or for working with colors or the lamp. Such
functions duplicate those provided elsewhere
in the menu system.
Edge Blending Procedure
NOTE: Before attempting to work with edge blending software functions, you must 1)
physically align the projectors/images by correctly overlapping the displays from your
intended external source, and 2) Match colors and Brightness Uniformity.
IMPORTANT: For a shared edge, all Blend procedures and settings should be
identical on BOTH projectors.
1. Start with two projectors. Display full white field test pattern from both.
2. In the Edge Blending submenu, enable Edge Blending by entering a checkmark in
the top checkbox.
3.
SET STARTING POINTS FOR ADJUSTMENT:
 Set all blend widths to 0.
 Go to “More” and set everything in the Edge Blending (2) menu to 50.
