3. Gamma Correction Adjustment: Adjust the monitor's gamma
correction for optimal brightness with the red, green and blue slider
bars.
Note: You cannot adjust Gamma Correction for 256-color
modes
When these sliders are changed the gamma correction table
modifies each pixel's color value.
The brightness produced at the face of the display is proportional to
the input voltage raised to the power gamma. This nonlinearity
must be compensated to achieve correct reproduction of the image's
brightness. The effect of display gamma is to darken the midtones
relative to the dark and light regions. The gamma correction
adjustment affects the entire screen display. The possible setting
range is 0.3 - 4.0. The default setting is 1.0.
With Link sliders selected, the three sliders move together as you
drag any individual slider. With the check box unchecked, you can
adjust colors individually by dragging the applicable slider.
Click the >1< button - for each color - to set the gamma correction
to the default value of 1.0.
