Display Device: The options in the Display Device menu allow you to change the picture
orientation, adjust the amount of overscan and access other projector-specific functions.
•Configure: Select Configure from the Display Device menu. Then:
• Orientation: Select Orientation to change the picture orientation to suit the method of
installation (Floor Front, Floor Rear, Ceiling Front or Ceiling Rear).
• Overscan: Refer to Overscan on page 55.
• Fan Mode: If the projector is being used in a high-altitude environment, use the Fan
Mode control to prevent it from overheating. Set it to High Altitude (“1”) to run the fan
at high speed; set it to Normal (“0”) to run the fan at normal speed.
• Height: Select Height from the Display Device menu to adjust the displayed image
height in small increments. Higher values compress the height. This setting affects all
sources.
• Lamp Hours: To display the number of hours that the lamp has been in service, press
or to highlight Lamp Hours.
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.
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.
Use this control to fine-tune the image geometry on a Vision
85/CineWide. (It should not be necessary to change this setting on a
standard Vision 85.)
