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 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.
Note:
Changing the Top Edge,
Bottom Edge, Right Edge, or Left Edge settings resets the Black Level setting to its default
value.
