Monitor Gamma
In general, a monitor cannot display the full colour range of an image. In order to have the monitor approximate the Colours as closely as possible, you usually need to adjust the monitor gamma.
Adjustment of the monitor gamma can make the monitor approximate the Colours of the original image more closely. Choose this item, and the following dialog box will appear:
From this dialog box, you can adjust the brightness in the displayed midtones so that the monitor can approximate the colour details of the original images. Drag the scroll bars to adjust the gamma values of red, green, blue and grey until the monitor displays the original colours more accurately. If the Sync box is checked, you can adjust all the four gamma values simultaneously by dragging any scroll bar.
When the adjustment is done, click on the OK button to confirm your settings and close the dialog box; otherwise, click on the Cancel button to cancel your settings and close this dialog box. If you wish to use the default value, click on the Default button and the gamma value will be set to 1.4.
