The RGB gain adjustment is available for RGBHV, RGBS, RGsB, and
progressive component video inputs only.
The red, green, and blue gain screens display a status indicator that shows the
input signal gain (contrast) setting for each individual color. Use the Menu and
buttons to adjust each color’s gain control through a range of 0 to 255. The default
setting is 128.
An extra step is required to adjust the display, as follows:
1. Select the RGB Gain screen (see steps 1 through 4 in Status indicators in this
chapter).
2. Use the Menu and buttons to highlight the desired color option (such as
Red) and press the Enter button. The selected color’s gain status indicator
appears on the on-screen monitor.

selected level by 1 step or press and hold the buttons to flow through the
adjustment range.

Color Saturation screen
The color saturation adjustment is available for interlaced component video,
S-video, and composite video inputs only.
The Color Saturation screen displays a status indicator that shows the color
saturation setting. Color saturation increases and decreases the color of the picture.
Use the Menu and buttons to adjust the color saturation control through a range
of 0 to 255. At the minimum setting, 0, the scaler removes most of the color. The
default setting is 128.
Hue screen
The hue adjustment is available for NTSC interlaced component video,
S-video, and composite video inputs only.
The Hue screen displays a status indicator that shows the hue setting. Hue adjusts
the picture’s color toward red or green. Use the Menu and buttons to adjust the
color saturation control through a range of 0 to 255. Press the Menu button to
increase the green (and decrease the red). Press the Menu button to increase the
red (and decrease the green). The default setting is 128.
Sharpness screen
The sharpness filters are available for interlaced component video, S-video, and
composite video inputs only.
The Sharpness screen displays a status indicator that shows the sharpness setting.
Sharpness uses variable filtering to affect input picture detail and definition. Use
the Menu and buttons to increase or decrease the sharpness filtering through a
range of 0 to 8. The default setting is 3.
Increasing the sharpness gives the visual affect of decreasing the noise filter
setting (see Noise filter screen in this chapter). Although the two filters
appear to counteract each other, the two adjustments are completely separate.
Adjust both settings for optimum picture quality.
