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.
