Black Level

You can adjust the brightness and tone differences in overlapping images.

Color Adjustment: You can adjust the brightness and tone of the areas. The adjustment areas are displayed based on the Edge Blending setting. When multiple screens are overlapping, adjust overlapping areas starting with the brightest areas first. Adjust the non-overlapping area (darkest part) last.
Area Correction: If the tone for some areas does not match, you can adjust it individually.
Reset: You can reset all adjustment values on the Black Level menu to their default settings.

Note:

The Black Level feature is only available when the following conditions are met in the Edge Blending settings.
- When Edge Blending is set to anything except for Off.
- When at least one of Top Edge, Bottom Edge, Left Edge, and Right Edge are set to On.
You cannot adjust the Black Level setting when a test pattern is displayed.
If the Geometry Correction value is very large, you may not be able to adjust the Black Level correctly.
The brightness and tone may differ in areas where the images overlap as well as in other areas even after performing Black Level adjustment. If you change one of Top Edge, Bottom Edge, Left Edge, and Right Edge, the Black Level setting returns to its default value.
