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 4-6. 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.

When you change an input position setting, save the change to a
preset afterwards. Otherwise, the change will be lost when a
different input is selected. (The input position settings are saved for
each input and resolution separately.) For information about saving
settings, refer to
ISF Presets on page 39.
