distort any picture other than 16 x 9 aspect ratio pictures. 16 x 9 can be used to display
anamorphic DVDs on an array.

One to One maintains the original size and aspect ratio of the picture. This may leave
blank areas on all four sides. For instance, a VGA picture (640 x 480) on a 16 x 9 display will
occupy only a small area in the center of the screen. The primary use of One to One is to
display the image without scaling artifacts.
The One to One Scale Mode will produce different cropping results and the image size will
be different for each input resolution.
