Section 3: Operation
Alternatively, if neither default is ideal, you may prefer to apply the simple (non-optimized) gamma curve or a
user-defined custom gamma curve that has been created externally, named, and downloaded to the projector
(requires separate PC-based Arbitrary Gamma and KoRE Librarian software applications). If any of these
special user curves have been installed, their names appear in the
Keep in mind that any Gamma Table choice sets the related Gamma value (shown in the
menu) to a 2.2 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 slidebar 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 gamuts 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 Saturation secondary menus, 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 Saturation
secondary menu.
NOTES: 1)
"Color Temperature" defaults to 6500K until changed. All four "User" options default to SD Video

gamut from projector-to-projector, can be altered in the Service menu only. If you suspect alteration, the
factory settings can be recovered with selection of Reset to Factory Defaults? in the Service menu
(password-protected).
Color Temperature
Adjust to apply a specific color temperature to all displays. Color temperatures are expressed in degrees Kelvin
(3200-9300K), and utilize different combinations of the projector's original native color primaries to produce a
"coloration" or cast (reddish or bluish) in images-the lower the temperature, the more reddish the cast; the
higher the temperature, the more bluish the cast.
NOTE:
The slidebar is only enabled if you have a source connected, and have selected "Color Temperature" in the
adjacent "Select Color Adjustment" drop-down list in the Advanced Image Settings menu.

Frame Delay Monitor
This slidebar monitors the latency between input and output. For best results, the bar width and value should
remain fairly constant, indicating that timing of input and output frames is locked; the Frame Delay Monitor
value should stay within 5-10 lines or so of the Frame Delay setting. If a frame is lost or "dropped", the slidebar
moves suddenly and the values change, indicating that the frame input is no longer equal to the output.
