Operation

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 41.

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 2.20 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.

To adjust the Crystal Series LCD audio settings, select Audio from the Main Menu and press ENTER.

Balance: To adjust the left/right speaker balance, select Balance from the Audio Menu and press ENTER. Use the left- and/or right-arrow buttons to make one channel louder than the other.

Equalizer: The Crystal Series LCD has a five-band graphic equalizer that you can use to boost or cut certain audio frequencies. To use it, select Equalizer from the Audio menu and press ENTER. Select one of four equalizer presets – Standard (flat), Music, Film or Speech – or select Custom to create your own according to taste. The five frequency bands are 100, 300, 1000, 3000 and 10,000 Hertz (Hz).
