Sharpness: “Sharpness” is the amount of high-frequency detail in the image. To adjust
sharpness, select Sharpness from the Picture Adjust menu and press ENTER. On your
external test pattern source, select a pattern like the one shown in Figure 4-8. Adjust as
needed, looking for white edges around the transitions from black to gray and different sized
lines in the “sweep” patterns at the top and bottom. Lower the sharpness setting to eliminate
them.

Gamma: The Gamma control 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-between” values
utilized in other grays.
Unlike brightness and contrast controls, Gamma allows you to lighten or darken the overall
tone of your images without changing the extremes. All images will be more vibrant while
still showing good detail in dark areas.
The default Gamma setting is appropriate for most typical home cinema environments.
