Setup the black level blending
Blending should only be used in cases where the projector has overscanning which cannot be disabled. Disabling projector overscan will provide much better results and will be significantly easier to maintain.
While the Black level regioning mode is enabled, then you can configure the blending using the normal blending tool’s. When using the Blending, a small overlap can be used to hide/smear out the sharp edge between the non-overlapped, and the overlapped area. This is achieved by defining the non-overlapped area a few pixels into the projector overlap area. If the blend area is too wide, then this can cause some unwanted artefacts within the blend area.
