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 pa
ttern like the one shown in Figure 4-5. Adjust as
needed, looking for white edges around the tra
nsitions from black to gray and
differently-sized lines in the “sweep” patterns at the top and bottom. Lower the Sharpness
setting to eliminate them.
