TV Display Format Video Output
Standard (4:3) Mode Normal (4:3) video plays normally and 16:9 video has the left and
right sides cropped off (center cutout).
Letterbox Mode Nor mal (4:3) video plays normally and 16:9 video has all the
picture viewable with black bars on the top and bottom
(letterbox).
Widescreen TV Normal (4:3) video plays normally and 16:9 video displays all the

TV Display Format Video Output
Widescreen TV 16:9 video plays normally and 4:3 video has black bars left and
right (pillar box). This relies on the TV responding to aspect ratio
switching signals on VBI line 23 (PAL only). On TVs that don't
respond to this signal, you must set the TV aspect ratio manually
to avoid a stretched or squashed picture.
