Edge Smoothing submenu

The Edge Smoothing submenu turns the edge smoothing feature on and off. Edge
smoothing smooths edges of a picture by minimizing the differences between
pixels.

Use either the Adjust knob or the Adjust knob to select On (the default) or Off.

Blue Mode submenu

The Blue Mode submenu turns the blue mode feature on and off. Blue mode is
helpful in the setup of the connected displays’ monitors. In the blue mode, only the
sync and blue video signals are passed to the display.

Use either the Adjust knob or the Adjust knob to select On or Off (the default).

Test Pattern submenu

The Test Pattern submenu selects from among several test patterns. The test
patterns are helpful when adjusting the connected displays for color, convergence,
focus, resolution, contrast, grayscale, and aspect ratio.

Use either the Adjust knob or the Adjust knob to select a test pattern. The
options are: Off, Color Bars, Crosshatch, 4 x 4 Crosshatch, Grayscale, Crop,
Alternating Pixels, Film Aspect Ratio 1.78, Film Aspect Ratio 1.85, Film Aspect
Ratio 2.35, and Ramp. The default is Off.

Blanking submenu

The Blanking submenu displays and sets the top and bottom line blanking.

Use the Adjust knob to adjust the top blanking and the Adjust knob to adjust
the bottom blanking.

RGB Delay submenu

The RGB Delay submenu displays and sets the RGB delay. With RGB delay, the
DDS 402 switches to the new sync signal before switching RGB (video) signals.
This allows a brief delay for the displays to adjust to the new sync timing before
displaying the new picture, which will appear without glitches. RGB delay is also
known as Triple-Action Switching or video mute switching.

Use either the Adjust knob or the Adjust knob to select the blanking period
(RGB delay time) from 0 seconds to 5 seconds in 0.1 second steps. The default is 0.7
seconds.
