ACCESS LEVEL:
Operator
Description
This control lets you select the Gamma table. You can select from one of the standard tables, or select an
arbitrary Gamma table that has been downloaded into the projector. A separate PC utility is needed to do this. The
2.22 table is a simple power curve. The standard table is a modified 2.22 curve with an optimized linear portion in
the low end of the curve. This is the same as selecting a custom table and setting the function to be 2.22 and the
slope to be 1.0. Selecting Gamma Function from the drop-down list enables the Gamma Function and Gamma
Slope controls.
Valid values are:
0 = Standard
1 = 2.22
2 = Gamma Function

Description
Defines the gamma power curve to be used when the Gamma table value is set to ‘Gamma Function’. This value,
combined with Gamma Slope setting, determines the Gamma table to be used. The curve is generally a power
curve with a small linear segment at the bottom defined by the slope.
The valid range is 100-300, where 100 is 1.0 linear and 300 is a 3.00 power curve.
