White Balance: To remove any trace of color from the white areas of the projected image, choose White Balance from the Set Up menu and press ENTER.
•Gamma: “Gamma” is a global setting that determines how gray shades are displayed between minimum input (black) and maximum input (white) for all signals. A good gamma setting helps to optimize blacks and whites while ensuring smooth transitions for the
In all but the most unusual situations, the appropriate “Gamma Selection” (see below) will produce accurate colors and a satisfying contrast level. However, it is sometimes necessary to adjust the red, blue and green gamma curves individually. To do this, select Gamma from the White Balance
•Gain: Use the Gain controls to correct color imbalances in the bright areas of the image. A good way to do this is to use a test pattern consisting mostly of solid white areas, such as an 80 IRE “window” pattern. If the white areas contain traces of red, green or blue, decrease the Gain for that color.
•Offset: Use the Offset controls in the White Balance
•Store Color Temp.4/Store Color Temp.5: When you are finished adjusting the Gamma, Gain and Offset, select Store Color Temp.4 or Store Color Temp.5 to store your settings. To recall them, set the Color Temperature to +4 or +5 in the Image Adjustment menu (refer to Picture Adjustment on page 32).
Gamma Selection: The normal gamma setting of 2.2 is correct for almost all signals and conditions. If excess ambient light washes out the image and it becomes difficult or impossible to see details in dark areas, lower the gamma setting to compensate. This will improve contrast while maintaining good details for blacks. Conversely, if the image is washed out and unnatural, with excessive detail in black areas, increase the setting. Again, good gamma improves contrast while maintaining good details for blacks and whites.
