In full-screen mode, there is no cropping. Pictures are decimated horizontally or
vertically for the correct aspect ratio. This decimation may cause some artifacts.
This behavior may be evident on a sweep signal. Also see the online help for the
Picture Aspect Ratio for related information. Display can be set to include Closed
Captioning text or Teletext subtitles overlaid on the picture.
