Picture Adjustment
6.2.0.1 Brightness
The brightness function is used to adjust the overall light output. Adjust the Brightness value between 0 and 100.
6.2.0.2 Contrast
The contrast function is used to adjust the contrast between the light and dark areas of the displayed image. A
correct contrast setting is important for good image reproduction. Adjust the Contrast value between 0 and 100.
6.2.0.3 Color
The Color function (or Saturation) is used to adjust the color saturation levels. Adjust the Color value between 0 and
100. 6.2.0.4 Hue
The hue function is used to adjust the color tint to obtain true color reproduction. Adjust the Tint value between 0
(more red) and +100 (more green).
6.2.0.5 Sharpness
The Sharpness function is used to adjust the image sharpness of the picture. Adjust the Sharpness value between
0 (soft) and 100 (sharper).
6.2.0.6 Color Temperature
Color temperature stands for the spectral properties of a light source. Low color temperature implies warmer
ambiance (more yellow/red) while high color temperature implies a colder light (more blue).
Color temperature can be set to Low, Medium, High and User.
The User setting allows a fine adjustment of the Gains and Bias values for red, green, and blue channels and a
correct black and white balance.
Gamma
Gamma is the relationship between the color values of the data and the color values displayed. The Gamma
coefficient makes it possible to adjust the brightness of the midtones only without affecting the very bright and very
dark areas. If gamma is set too high, middle tones appear too dark. If it's set too low, middle tones appear too light.
The Gamma correction factor can be set to:
Gamma 1 this setting is recommended with computer sources.
Gamma 2 for standard viewing.
Gamma 3 for movie projection.
Gamma 4: this setting is recommended for dark room.
Gamma 5 features a fine adjustment of the gamma response on the complete 0-100 IRE scale for untypical light
environment. This setting can be modified by certified installers.
Accurate picture calibrations may require professional tools such as dedicated software and colormeter.
Wait at least 20 minutes after startup before modifying the picture settings.
