Advanced Edge Blending Controls - Christie Entero RPMWU User Manual

Section 3: Operation
NOTE: For information about advanced blending of complex configurations, for example with spherical
screens, see the Twist User Manual (P/N: 020-100143-xx) included in the user kit.
Blend Width determines how much area is used for blending along an overlapping edge. Slide bar values
represent the number of pixels used for the blend. For example:
• A setting of "eight" creates a blended edge 8 pixels wide.
• A setting of "0" signifies no blending.
• For best results in most applications, use a blend width of 12-25% (for example with a screen size of
1920 × 1200, 230-480 pixels).
WUXGA Ranges: 0-960 horizontal, 0-600 vertical
SXGA+ Ranges: 0-700 horizontal, 0-525 vertical
Show Blending Overlap turns your defined blend width area to solid grey so that, if needed, simply
overlapping the grey bars can seamlessly align two adjacent images. Toggle the Show Blending Overlap off
to reactivate the blend effect.
Other Functions - For convenience, the Edge Blending submenu also includes related options for enabling a
test pattern. Such functions duplicate those provided elsewhere in the menu system.

IMPORTANT: For most display wall
installations, see the Entero Installation
Guide for information about matching
edges in a display wall installation.
Software edge blending should not be
required for these installations.
• Blend Shape determines the rate of roll-
off across the blend width, i.e. how
quickly the white levels across the blend
change from light and dark. Increasing
the Blend Shape setting accelerates the
rate of change at both extremes so that
less of the region appears mid-grey.
Decreasing the Blend Shape setting
slows the rate of change so that more of the region appears mid-grey. For most applications, this subtle
control is best left close to 50.
• 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.
