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
— SUBMENU
This submenu consists of the
following options:
ACTIVE INPUT WINDOW: This 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
INPUT
3
or INPUT 4, the default blanking of “0” defines an active input window of 720 x 483.
BLANKING (TOP, BOTTOM, LEFT, and RIGHT):
Crop the image as desired so that unwanted
edges are removed from the display (changed to
black—see right). 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. 13). For example, left Blanking zooms
the right side of the PIP image; Right Blanking
zooms the left side. There are no black bars.
