Background Color submenu
Rotate either Adjust knob to select a background color for the output screen.
Options are None, Red, Green, Blue, White, Magenta, Cyan, Yellow, Stored-Image, and
User Defined.
• None, the default setting, produces a black background.
• Stored-Image is the saved background that was most recently recalled. When a
captured background is recalled, the Stored-Image option is automatically
selected. Select this option if you want to return to the recalled background
after having changed to a different background color.
• User Defined is the background color that you can set by using an SIS
command. See chapter 4, Software Configuration and Control, for the command
syntax.
Blue Mode submenu
Blue Mode causes only sync and blue video signals to be passed to the display.
This can aid in the setup of the MGP 462’s color and tint. While in the Blue Mode
submenu, rotate either Adjust knob to turn Blue Mode on and off.

Several test patterns are available via this submenu to adjust the display device for
color, convergence, focus, resolution, contrast, grayscale and aspect ratio. Use
