Aspect Ratio Conversion Policy Options
Note:
The commands for setting/verifying the aspect ratio conversion policy are on the previous page.
Stretch
(to fit) – This aspect ratio conversion policy option (default) scales the video to full screen size in both horizontal
and vertical directions regardless of the input aspect ratio. No data is cropped. However, the image may be distorted as
needed to fill the screen. When Stretch is selected, black bars are not added by the scaler. However, if an image has
originated from a source device with either horizontal or vertical black bars (e.g., letter box from a movie), the black bars
will be considered as active video and will be included in the stretched video.
Maintain (
aspect ratio) – This aspect ratio conversion policy option maintains the incoming video’s aspect ratio, but will
scale the image until the display fills either horizontal or vertical direction first. If the vertical direction is filled first, then
the video will have pillar box black bars on the sides of the display. If the horizontal direction is filled first, then the
video will have letter box black bars on the top and bottom of the display.
Zoom
– This aspect ratio conversion policy option maintains the input aspect ratio while zooming the image to fill the
screen in all directions. Image data may be lost on the top and bottom or to the left and right of the displayed image.
Anamorphic
– This aspect ratio conversion policy option is used with anamorphic formatted video sources so that the
images appear correctly on the display.
