Adjusting the Black Level

When two images overlap, the overlapping area can appear differently from the areas that do not
overlap. You can use the projector's Black Level setting to make the difference less noticeable.
Note: You cannot adjust the black levels while projecting a test pattern, and you may not be able to
adjust the black levels correctly if the Geometry Correction settings are set too high. The brightness
and tone of the overlapping areas may differ from the rest of the image even after adjusting the black
level.
