Advanced screen

The Input submenu’s Advanced settings are a comprehensive set of adjustments to optimize the switcher for non-standard video inputs. Most users do not encounter such signals. For those users who do, the switcher automatically adjusts these settings. The switcher’s automatic adjustments are adequate for most inputs.

The Advanced screen provides a submenu of advanced selection options: active pixels, active lines, phase, horizontal and vertical start, and total pixels. These advanced settings are rarely needed for standard video and computer video signals, but provide the user with manual control over scaling parameters that are automatic. The knowledgeable user may need to adjust these settings to optimize his or her input signal(s). Possible reasons to adjust these settings include tolerance issues and nonstandard resolutions and frequencies. The settings are described in more detail as part of the discussion on optimizing the video. See “Input submenu’s Advanced selections”, on page 3-33.

To select one of the advanced settings, use the front panel or IR remote control or button to highlight the desired status indicator bar.

Input 5 selection

The Input 5 selection displays a selection box that shows the currently assigned component video format (interlaced [NTSC/PAL/SECAM], progressive [480p/576p], or HDTV [720p/1080i/1080p]) for input 5 and allows you to select a different format.

Use the front panel or IR remote control and buttons to highlight the desired component video format. Press the Enter button to change to the highlighted value. The default is progressive.

Picture submenu

Figure 3-14 is a flowchart that shows an overview of the Picture submenu, its available status indicator bars, and their available settings. Use the front panel or IR remote control and buttons to highlight the desired status indicator bar.
