Gamma Correction Adjustment

: Adjust the monitor's

gamma correction for optimal brightness with the red, green and

blue slider bars.

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.

4 Click the Apply or OK button to enable your Adjustment

settings.

Notes

(1) Press the ESC key on your keyboard to undo the

changes if your monitor has lost synchronization. You may

also use the keyboard shortcut for ‘Undo’ - Alt-U.

(2) If you change the resolution (in Settings) and/or the

refresh rate (in Monitor), you may need to re-adjust the

monitor's display.

Note

The Gamma Correction Adjustment settings apply to both

monitors, if you have two monitors connected to the Fire GL

8800.
