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 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.

  2. Select the Extended menu and press Enter.
