Return to User OSD	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 sub-menu and use the left- and right-arrow
	buttons to manipulate the on-screen slidebars.

• 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 sub-menu to correct color imbalances in the dark areas of the image. A good way to do this is to use a test pattern consisting mostly of dark gray areas, such as a 30 IRE “window” pattern. If the gray areas contain traces of red, green or blue, decrease the Offset for that color.

• 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 48).

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.

SD Enhance: The SD Enhance menu gives you options for improving the quality of standard-definition, 480i images. (For 480p and higher-definition images, the controls in this menu are disabled.) Keep in mind that these controls add frequencies that are not present in the original signal, and may make images appear “noisy” if misused.

•H Enhance/V Enhance: These controls can improve the apparent horizontal and/or vertical resolution of the image.

•Chroma Enhance: This control adds chroma (color information) to the input signal and can make colors appear more vibrant and saturated.
