To enable seamless switching, input 4 must be configured as RGB passive
(unscaled) on the Signal Format screen. However, once it is configured as
passive and if input 4 is selected, on-screen menus are not displayed.
No video adjustments are available for the input 4 video signal when it is
configured as passive (unscaled) but audio and other input variables are still
adjustable. Because on-screen displays will be blanked for input 4 once it is
configured as passive, it will be helpful to configure all of the input 4 options
before you configure the input as passive. If, later, you need to change any of
the input 4 settings, the easiest way is to temporarily set input 4 to one of the
scaled output settings. See Signal Format screen in this chapter.
Alternatively, you can make the adjustments under RS-232 control.
Status indicators
Most of the Video and Audio menus (see Video menu and Audio menu in this
chapter) and a select few Output menu operations (see Output menu in this chapter)
are performed using on-screen status indicators (figure 3-6) that resemble slide bars
but are controlled using the Menu and buttons.

Unless shown in the Video menu and Audio menu subparagraphs, adjusting the
Video and Audio menu settings is accomplished as follows:
1. For the Video, Audio, and Input menu screens, select the input that you want
to adjust by pressing that Input button.
