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.
