Sharpness: “Sharpness” is the amount of high-frequency detail in the image. To adjust
sharpness, select Sharpness from the Picture menu and press ENTER or SELECT. On your
external test pattern source, select a pattern like the one shown in
Figure 4-5. Adjust as
needed, looking for white edges around the transitions from black to gray and
differently-sized lines in the “sweep” patterns at the top and bottom. Lower the sharpness
setting to eliminate them.
