Color Temperature: To choose a color temperature setting, 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.
Each color temperature setting has six (6) “white balance” parameters associated with it
(two each for red, green and blue). These are described later in this section; refer to
White
Balance on page 39.
Gamma: The Gamma control determines how gray shades are displayed between
minimum input (black) and maximum input (white) for all signals. A good gamma setting
helps to optimize blacks and whites while ensuring smooth transitions for the
“in-between” values utilized in other grays.
Unlike brightness and contrast controls, Gamma allows you to lighten or darken the
overall tone of your images without changing the extremes. All images will be more vibrant
while still showing good detail in dark areas.
The default Gamma setting of 2.2 is appropriate for most typical home theater
environments.
Save Settings: The Crystal Series LCD lets you save image quality settings for each input
and supported resolution to a preset. You can recall this preset at a later time by simply
pressing a button on the remote control or using the Restore Settings menu command
(see below).
You should save changes to any of the following settings to a preset; otherwise they will
be lost when a new input source or resolution is selected:
• Brightness
•Contrast
• Color saturation
•Tint
• Sharpness
•Gamma
• Color temperature selection (5400, 6500, 8500 or Custom)
Restore Settings: To recall a preset, choose Restore Settings from the Picture Adjust
menu and select “Custom,” “ISF Day” or “ISF Night.” Or, use the corresponding buttons
on the remote control.
