Sharpness:
“Sharpness” is the amount of high-frequency detail in the image. To adjust
sharpness, select Sharpness from the Picture menu and press
ENTER
. 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.
