Black Level Blending Procedure
NOTES: 1) Adjust white levels before adjusting black levels. 2) The zones in BLB menu correspond to the
Edge Blend zones. If a given Edge Blend zone width is set to 0 (i.e. no blend on that side) then the
corresponding BLB zone is disabled. It only becomes accessible when that Edge Blend zone is active.
1. Start with two projectors. Select the black test pattern for both projectors from the Geometry and Color
submenu.
2. In the Black Level Blending submenu, enable black blending by putting a check mark in the check box for
each projector.
3. Working with 1 projector at a time, use the
center brightness slide bar to adjust the
center brightness (brightness of the non-
blended region) so that the center intensity
matches that of the brightest blended region
(the center of all images when blending a 2 x
2 display is the target area).
4. Use the following 3 color slidebars, Black
Red Level, Black Green Level and Black
Blue Level, so the black hue of each
projector matches.
