Black Level Blending Secondary Menu
Black Level Blending is a feature that eliminates the differences between black levels when edge blending
multiple projectors. The Black Level Blending submenu provides many controls to allow the edges of
adjacent images to be smoothly overlapped creating a "seamless" image. Black Level Blending provides a
simple solution for uneven black levels, without the need for external hardware, by matching up black level
hues with a "target area" hue (the intersection of the center lines), and adjusting the overlaps (edges)
surrounding the target area.
