• All digital and decoder option cards do not present an additional auto setup menu since digital
hardware provides enough information to perform the correct auto setup.
• Analog PC graphics sources (four/five-wire sync) present a list of formats based on the current
active lines detected in the video.
• Analog Video Sources (three wire sync on green) always have the options
Default
and
Advanced
. Video sources use a look up table to determine their format based on video
standards. The
Advanced
auto setup selection measures the start pixel and start line whereas
Default
uses the table values as is.

Changing the size and position of the image
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 used at the site. Changes made in the Size and
Position
menu are applied immediately and are saved when you exit the menu (press
Exit
or
Menu
).
Resize presets
The same resize presets are available to all HD and SXGA+ screen models. However, the graphics
used to describe each preset in this section are of the SXGA+ models only.
Resize Presets
displays an image in its
native resolution (no resizing) or resizes
the image by maximizing either the
height, width or both height and width, or
resizes to the maximum size possible
while keeping the original aspect ratio.
Size, Position
and
Blanking
parameters
automatically adjust accordingly or, if
Blanking
is set first, which defines an
active input area;
Resize Preset
scaling
occurs in this region of interest only.
Resizing options are explained below.
By default, when displaying a new source
your image uses as much of the display
area as possible for the type of incoming source data, but with minimal or no changes to aspect
ratio.
The custom re-size descriptor automatically appears in the Size and Position menu when any of the
values for Size, Vertical Stretch, H-Position, V-Position or Blanking do not correspond to those for a
preset. This option is not offered in the Resize Presets list.
