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 level when a test pattern displayed. The brightness and tone of the overlapping areas may differ from the rest of the image even after adjusting the black level. 1. Press the Menu button. 2. Select the Extended menu and press Enter. 3. Select the Multi-Projection setting and press Enter. 4. Select the Black Level setting and press Enter. 141
