If some shimmer from a video or HDTV source persists, use the "Filter" control to
remove high-frequency noise from the signal.
H-Position
This option moves the image right or left within the area of available pixels.
NOTE: The value shown represents where the approximate center of the image lies
in relation to the total number of pixels available horizontally. This varies widely
according to the signal—watch the image while adjusting.
V-Position
This option moves the image up or down within the area of available pixels.
NOTE: The value shown represents where the approximate center of the image lies
in relation to the total number of pixels available vertically. This varies widely
according to the signal—watch the image while adjusting.
Advanced Size and Position
This submenu consists of the
following options:
ACTIVE INPUT WINDOW:
read-only value indicates the
current size (i.e., area) of your
displayed data or "region of
interest" as defined by the
blanking controls. By default, the
projector automatically
determines what portion of its full resolution to use, and pixels in the surrounding
borders are turned off. You can also specify a specific active input window size by
adjusting one or more "Blank" settings. For example, if you have blanked (cropped)
100 pixels from both the left and right edges of an incoming source of 1400 x 1050,
the remaining active input window will be reduced to 1200 x 1050. When using SD
or HD or a decoded video source at
defines an active input window of 720 x 483.
BLANKING (TOP, BOTTOM, LEFT, and
Crop the image as desired so that
RIGHT):
unwanted edges are removed from the
display (changed to black—see Figure 3.14).
Blanking defines the size of the Active Input
Window, or area of interest. Range of
adjustment depends on the source resolution
and other factors. After adjustment of
blanking it may be necessary to perform a
source switch.
NOTE: Blanking a PIP image resembles
zoom (Figure 3.15). For example, left
Blanking zooms the right side of the PIP
image; Right Blanking zooms the left side.
There are no black bars.
