• Aspect Ratio – this pulldown allows selection of one of four aspect ratio
conversions on the downscaled HD electrical outputs. (This control has
no effect on SD downscaled outputs.):
• Anamorphic – this mode converts a 16x9 HD image to a 4x3 SD image.
Shapes are not preserved causing them to stretch vertically as
shown in
