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
used at the site.
Refer to "Using Slidebars and
Other Controls" (earlier in this
section) if you need help using any
of the options and controls.
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
NOTE: The same resize
presets are available to the
widescreen format DW30.
Please note however, the
graphics used to describe each
preset are of the SXGA+
models only.
Select a Resize Presets option
to quickly display an image in
its native resolution or to
automatically resize an image to closely fill the projector’s native resolution or to
optimize the width or height of your display. 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 in detail 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.
WHEN “CUSTOM” APPEARS: 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.
