(2) Selecting an SD (shading) value
Shading adjustment refers to correction of unevenness in sensitivity between the center and rim of the screen due to lower
light intensity or other causes. You can perform shading adjustment by the illumination and optics methods.
DS-L3 provides two type of shading adjustment: standard adjustment values of 10% to 50% and seven user-defined
adjustment values.
Use of the standard adjustment values and user-defined shadings
•
Use the 10% to 50% standard adjustment values for compensating the light intensity degradation from the center
to the rim of the screen.
Select a value viewing the screen.
