graphics and video sources. The Standard curve (auto setup default) is a modified 2.22 curve with a
small linear section in the black that enhances the detail in darker areas of the projected content.
Typically Standard or 2.22 is used for all sources. Alternatively, if neither default is ideal, apply a
simple gamma curve by defining a custom power function and slope. Select Gamma Function to
enable the function and slope controls.
Gamma Function
Defines the base gamma power curve used when Gamma is set to Gamma Function. This value,
combined with the Gamma Slope setting determines the base Gamma table to be used as the custom
base table. The curve is generally a power curve with a small linear segment at the bottom defined by
the slope.
Gamma Slope
This control defines a slope to be used for the base custom Gamma table for a small section at the
bottom of the curve. This slope can be used to bring in or out the low level blacks in the image. This
slope, combined with the gamma function, defines the custom Gamma table.
i
For complex non-standard gamma curves, a user-defined curve created externally and
downloaded to the projector can be used (requires separate PC-based Arbitrary Gamma
software application to create the table, and the WebUI to download it). If any of these
special user curves have been installed, their names will appear in the Gamma drop-down
list.
