Advanced Image Settings
SUBMENU
GAMMA TABLE: This control selects
and applies the normal 2.2 gamma
setting or a user-defined "arbitrary"
(custom) gamma table that has been
previously downloaded to projector
memory (these custom
tables—a.k.a. curves—are created in
Runco's Arbitrary Gamma application
for the PC, and are downloaded via a
separate utility). Use of custom curves
can improve performance for certain
kinds of source input and applications.
Generally the best gamma curve is
one that produces maximum contrast, brightness and color performance for the current
signal and ambient lighting conditions.
NOTE: If no such curves have been defined and downloaded to projector memory, only
the "2.2, Normal" default gamma curve is available here—adjust as desired in the main
Image Settings menu.
SELECT COLOR ADJUSTMENT: In "Select Color
Adjustment", choose an overall color performance for all
images. The "Max Drives" factory default simply drives all
3 colors at their maximum level so that they are fully on
and cannot be changed. The two other pre-defined color
adjustment choices—SD Video and HD Video—apply a
color gamut optimized for video sources (standard or high-
definition). Alternatively, you can specify a color temperature,
which enables the nearby Color Temperature slidebar and
applies its current setting (default = 6500K). If none of the pre-defined "Select Color
Adjustment" options or color temperatures suit your application, select one of four
color gamuts previously defined by a user (ISF Day, ISF Night, 3, 4). A "User" option
applies a customized color performance in which the user has precisely set the
hue and intensity of each color component in the Color Adjustment by X/Y or Color
Saturation submenus, and is most often needed with multiple-projector applications.
Select the color adjustment producing the best color accuracy for your application
and installation.
