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.
