Black level uplift
Black in the blended regions appears less dark than in the rest of the image. To compensate
for this, use this menu to raise the black levels of the rest of the image:
•
Set All to the required amount of black level correction. This will apply equal
correction to the black levels of all colors.
•
If necessary, use the individual color sliders (Red, Green and Blue) for fine
adjustment.
You may experience artifacts at the edges where the blended region of one projector
overlaps the pond of mirrors of its neighbor. In the example below, the blended image

of each projector so it does not overlap the pond of mirrors of the other projector.

Depending on your array, use Top, Bottom, Left and/or Right to reduce the black level
uplift size. In the example below, use the Right slider of the projector on the left
