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.
Figure 4-5. Typical Test Pattern for Adjusting Sharpness
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.
