Configuring How An Image Is Cropped - Christie Mirage M Series User Manual

H-Position
Moves the image right or left within the area of available pixels. 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
Moves the image up or down within the area of available pixels. The value shown represents the
approximate center of the image in relation to the total number of pixels available vertically. This
varies widely according to the signal; watch the image while adjusting.
Keep Aspect On Auto Setup
Ensures that auto setup for any source maintains the input aspect ratio when the default size is
calculated. If disabled and the source is not a special case video source where a default stretch is
defined, the source is scaled to fit the platform.

Configuring how an image is cropped

Blanking defines the size of the Active Input Window, or area of interest, and crop the image so that
unwanted edges are removed from the display (changed to black). The range of adjustment depends on
the source resolution and other factors.
1. In the Size and Position menu, select Blanking.
The Active Input Window value indicates the current size 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.
Blanking a PIP image resembles zoom. For example, left
Blanking zooms the right side of the PIP image; Right
Blanking zooms the left side. There are no black bars.
2. To specify a specific active input window size by adjust
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 is
reduced to 1200 x 1050.
