PRELIMINARY
HD Format: If the characteristics of the incoming signal on the HD1 or HD2 inputs are
known, select HD Format from the Service menu and set them as described below. Doing so
can reduce the time it takes the VHD Controller to switch from HD to 480i signals or vice
versa.
This is generally not necessary unless the VHD Controller – for whatever reason – has
difficulty determining the color space (RGB or YUV), bandwidth or resolution of the incoming
HD signal. In most situations, the Auto settings work well.
• HD/RGB 1 and HD/RGB 2 (Color Space): Select Auto, RGB or YUV.
• ADC Bandwidth: Select Auto, 75 MHz, 150 MHz or 300 MHz.
• YPbPr Input Resolution: Select Auto or specify the input resolution, if known: 480i, 480p,
576i, 576p, 720p or 1080i.
Triggers: Select Triggers from the Service menu to configure the 12-volt trigger outputs. You
can assign one or more trigger outputs to each aspect ratio. Those triggers are then activated
by selecting that aspect ratio.
If your projector is equipped with the Vidikron CineWide with AutoScope system, assign at
least one trigger output (the same one to which the lens motor is connected) to the Cinema
and Intelliwide 2.35 aspect ratios.
To save the trigger settings so that they can be restored after a System Reset (described
below), press repeatedly to highlight “Save.” Then, press ENTER.
Miscellaneous: Select Miscellaneous from the Service menu to set the following options:
• Language: Select Language from the Miscellaneous menu and press the up- or
down-arrows to select the OSD language. (Currently, only English is supported.)
•Menu Mode: This is the manner in which the OSD menus appear and disappear when you
press MENU. Choose one of the following:
0 = No transition; menus abruptly appear and disappear.
1 = Menus fade in and out.
2 = “Checkerboard” dissolve; menus appear and disappear in sections.
3 = “Window shade” effect; menus are drawn on a diagonal from top left to bottom right,
and retract in the opposite direction.
• Timeout - Short/Long: These settings control how long the OSD menus stay on screen.
Select a time-out period of from 2 to 60 seconds.
• Side Bar Color: This controls the color of the inactive image area. The range is from -100
(black) to 100 (white).
The inactive image area is on either side of the active image area when using the Standard
4:3 aspect ratio, and above and below the active image area when using the Letterbox
aspect ratio.
•Film Mode: Enable Film Mode to smooth out moving images from interlaced,
standard-definition (SD) sources. In most cases, the VHD Controller detects the proper
“pull-down” rate and vertical frequency. However, if your source is jittery and/or tearing
you may wish to enable Film Mode to ensure stable processing for that source.

To configure a trigger to activate when the system is turned on –
for example, when using the trigger to control a retractable screen –
assign that trigger to all aspect ratios.
