GAMMA 2

Gamma is an image quality enhancement function that offers a richer image by brightening the darker portions of the image without altering the brightness of the brighter portions.

Three gamma settings are available to allow for differences in the images displayed and in the brightness of the room.

When you are displaying images with frequent, dark scenes, such as a film or concert, or when you are displaying images in a bright room, this feature makes the dark scenes easier to see and gives the impres- sion of greater depth in the image.
