5.2.2 COLOR TEMPERATURE

• The effect of Offset is roughly the same as “Brightness”. It adjusts the overall video level

of the image. The most obvious effect is that when it is increased, you’ll see the black

level of the image become brighter

• The effect of Gain is roughly the same as “Contrast”. It adjusts the total video output level

of Crystalio II. The most obvious effect is that when it is increased, you’ll see the white

level of the image become brighter, thus giving you a similar effect to more contrast

R, G, B is individual Red, Green, and Blue channels of the image. Adjusting individual

channels gives you control of that individual color

• Both Offset and Gain can be used to adjust the picture’s color balance. Gain can be

used to lower the overall dominance of one color. Offset can be used for fine

adjustments and adjustments that affect the lower end of the grayscale more. Use

commercially available calibration DVDs that contain grayscale ramps and other similar

patterns to verify color balance adjustment results

• Use the Left/Right arrow remote control keys to adjust the sliders

• Use the Up/Down arrow remote control keys to select between R, G, B Offset,

and R, G, B Gain

• When OK is pressed on the remote control, the whole OSD is hidden and only the slider

control is shown at the lower left corner of the display

• Pressing Back on the remote control will return you to the full OSD, or simply press the

Menu key to exit from OSD mode
