Advanced Image Settings — SUBMENU
Use the Advanced Image Settings submenu to make the
adjustments necessary for lesser‐used but more specialized
applications on your projector.
Gamma Table — This control applies a default video,
graphics or simple gamma table or "curve" to your images,
controlling the intensity of mid‐level colors and producing
maximum contrast, brightness and color performance. As
shown at right, the graphics curve is a modified power curve that will show
more detail in darker areas of the projected content while the video curve
has a linear segment near black to compensate for increased black levels
typical of video signals. A simple gamma curve is a true power curve that
does not alter the contrast or the intensity of mid‐level colors.
Keep in mind that any Gamma Table choice sets the related Gamma value
(shown in the Picture Adjustments menu) to a 2.4 default, where it can be
fine‐tuned as desired. Different values (1‐3) here indicate that the original
gamma table has been adjusted with either the Gamma slide bar or direct
key.
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 gamut previously defined by a user (User 1, 2, 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 Temp Adjust submenus, and is most often needed with
multiple‐projector applications. Select the color adjustment producing the best color accuracy for your application
and installation.
To configure a "User" color adjustment (gamut), use either the Color Adjustment by
X/Y or Color Temp Adjust submenu found in the Display Setup menu under Geometry
and Color.
NOTES: 1) "Color Temperature" defaults to 6500K until changed. All four "User"
options default to SD Video unless the user has redefined them. 2) Factory‐defined
color primaries, which insure consistent color gamut from projector‐to‐projector, can
