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 pattern like the one shown in Figure 4-5. Adjust as
needed, looking for white edges around the transitions from black to gray and different
sized lines in the “sweep” patterns at the top and bottom. Lower the sharpness setting to
eliminate them.

Color Temperature: To adjust the color temperature, select Color Temp. from the
Picture Adjust menu and press ENTER. (Color temperature defines the “color of gray.”)
The choices are 5400K, 6500K, 8500K and Custom. The default setting, 6500K, is
appropriate for most situations. Higher settings produce a “bluer” picture; lower ones
impart a reddish hue to the image.
Backlight: The Backlight control changes the apparent brightness of the displayed
image. Its effect is similar to that of a lamp intensity control on a projector.
