Runco SC-1 Owner’s Operating Manual 59
PRELIMINARY
Size and Position Menu In the Size and Position Menu, you can increase or decrease the size of your image,
change its proportion (aspect ratio), move the image to a specific area of the screen, and
refine other related parameters. Use Size and Position controls to match the image
precisely to the screen. Changes made in the Size and Position menu take effect
immediately and are saved when you exit the menu.
Resize Presets: Select a Resize Presets option to quickly display an image in its native
resolution, automatically resize an image to closely fill the projector’s native resolution or
optimize the display width or height.
The native resolution is 2048 x 1080 (1.90:1 native aspect ratio).
Size, Position and Blanking parameters automatically adjust accordingly. If Blanking is set
first, which defines an Active Input Area, Resize Preset scaling occurs in this region of
interest only.
For use with the DHD Controller, the default setting is No Resizing. This is almost always
the appropriate setting. Do not change it unless specifically instructed to do so by Runco
Technical Support.
• No Resizing: Select No Resizing to display the image in its native resolution, which
may not match the projector’s resolution. For example, for a computer display with a
native resolution of 800 x 600, “No Resizing” will use the central 800 x 600 pixels and
have a black border— the black border areas are unused areas.
Figure 3-31. Resize Presets: No Resizing
Other resizing options are described below, for the sake of completeness. In actual
practice, though, they are rarely (if ever) used when the SC-1 is used with the DHD
Controller.
• Default Resizing: When you select a new source, the image utilizes as much of the
projector’s display area as possible for the type of incoming source data, but with
minimal or no changes to aspect ratio. The image will be centered and displayed as
large as possible depending on the source type:
• A video image or graphic image is enlarged to fill the screen height, centered
between black side bars.
• An anamorphic (16:9) image will fill the height and slightly stretch horizontally to fill
the small amount of display area remaining on both sides.
The “native” aspect ratio is with the primary lens only. With 16:9
source material and an anamorphic lens in the light path, the
aspect ratio is 2.35:1.
