Widescreen (16x9) forces the aspect ratio to 16 x 9 (1.77), the standard for many DVD movies. This will distort any picture other than 16 x 9 aspect ratio pictures. Widescreen can be used to display anamorphic DVDs on an array.
Normal Video
No distortion
Compresses width to fit, no border
Fits height and width of image without distortion; fills width with border
Fits height of image, compresses width and fills with border
.
Normal Video (4x3) forces a 4 x 3 (1.33) aspect ratio, the ratio of standard television. Normal Video is used to display standard video on the analog or component inputs. Its resolution is 720 x 640, which is not 4 x 3, but it should be displayed as 4 x 3 (the pixels aren't square).
One to One
No distortion
Example above represents an XGA input on an XGA resolution display (1024 x 768)
Fits width of image without distortion; fills height with border
Example above represents a 1080i (1920 x 1080) resolution
Displays image without distortion at actual size with border on all sides
Example above represents a VGA input
Displays full image without distortion
Example above is for 1366 x 768 input on 1366 x 768 native resolution or 1920 x 1080 input on 1920 x 1080 native resolution
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. For UXGA sources on a 16 x 9 display, this will crop the picture top, bottom, and sides. The primary use of One to One is to display the image without scaling artifacts and with minor cropping.
The One to One Scale Mode will produce different cropping results and the image size will be different for each input resolution.
