•Lens: Select Lens from the Display Device menu to access the motorized lens controls. Refer to Primary Lens Adjustments on page 37.
•Auto Setup: Refer to Auto Setup on page 47.
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 DHD Controller to switch from HD to 480i signals or vice versa.
This is generally not necessary unless the DHD 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
