Setup Screen
The Gamma Adjustment slider on the Setup screen lets you simultaneously adjust
RGB color curves and define the color output for your display. You can also enter
a precise Gamma value, rather than use the slider, when you know which value is
appropriate for your monitor and ambient lighting conditions.
