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 43.

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.
