Color Setup
Select this submenu to work with
aspects of color—adjust for
saturation and overall hue in video
signals, or adjust gamma or
temperature in any signal.
COLOR —
"Color" adjusts the
color saturation level or the
amount of color in a video image. When set to "0' the image appears black and
white, and when set too high the colors appear overpowering and unrealistic. Use
and to adjust "Color" until the desired saturation level is displayed. For a
shortcut to "Color" slidebar, press
TINT —
"Tint" adjusts color hue to obtain true color reproduction of NTSC video
signals or HDTV signals. Use
is displayed in your image. It is best to adjust tint while displaying an external test
pattern—otherwise, it is recommended that tint remain at its default setting. For a
shortcut to "Tint" slidebar, press
SELECT COLOR TEMP —
preset color temperature (3200K, 5400K, 6500K or 9300K) or
any previously "User" defined color temperature. Color
temperatures are measured in degrees Kelvin and represent the
"coloration" (reddish or bluish) of the whites displayed by the
projector—the lower the temperature, the more reddish the
whites; the higher the temperature, the more bluish the whites.
NOTE: The custom temperatures "User" or "Interpolated
Color" can be defined in the Color Temperature Setup menu.
Until defined, these custom choices all default to 6500K. See 3.7, Configuring
System Parameters.
INTERPOLATED COLOR —
that lies somewhere between one preset color temperature and another. Adjust the
slidebar to define a new temperature which will be interpolated from the neighboring
presets (for example, 7841 is interpolated from 6500 and 9300). This slidebar is
disabled unless you have a source connected and have selected "Interpolated Color"
in the "Select Color Temp" pull-down list.
GAMMA —
NOTE: Gamma does not normally require adjustment and is intended for
experienced users only.
The "Gamma" option affects the shape of the curve determining
what gray shades are available for a given amount of signal
input between minimum (black) and maximum (white).
Different 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.
DEFAULT (default) –
