Size And Position Menu - Christie Mirage M Series User Manual

Section 3: Operation
• Analog Video Sources (3 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.

Size and Position Menu

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.
Resize Presets will display an image in its native
resolution (no resizing) or will resize the image
by maximizing either the height, width or both
height and width, or will resize to the maximum
size possible while keeping the original aspect
ratio.
Size, Position and Blanking parameters will
automatically adjust accordingly or, if Blanking
is set first, which defines an Active Input Area;
Resize Preset scaling will occur in this region of
interest only. Resizing options are explained
below.
WHAT IS THE RESIZING DEFAULT? By default when displaying a new source, your image will utilize 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. See Select "Default" below.
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 pull-down list.
• Select DEFAULT for most sources (factory default). The image will be centered and displayed as large as
possible depending on the type of source.
• NO RESIZING displays the image in its native resolution, which may or may not match the projector's
resolution. For example, for a source with a native resolution of 800 x 600, "No Resizing" in an SXGA+
projector will use the central 800 x 600 pixels and have a black border—the black border areas are unused
areas, see below.
