The gamma of a display describes the relationship between the video input signal level and the light output or intensity displayed on the flat panel. The Silicon Graphics 1600SW flat panel has an uncorrected gamma value of 1.8. Based on your work environment and how you use your display, you may want to choose a different gamma value. This gamma setting can be varied from 1.0 to 3.0.

To change the gamma setting, enter your preferred value in the gamma text field, then click the Apply button. This will cause your new gamma value to take effect immediately, and it will automatically save your current preset configuration with this new value.
