Description
Select 16:9 to view 16:9 DVDs
and HDTV programs in their
native aspect ratio.
4:3 images are stretched
horizontally to fit a 16:9 screen.
Standard 4:3 scales the input
signal to fit in the center of the
16:9 screen. 4:3 is the aspect
ratio used by computer
monitors, standard television
programming and most VHS
video cassettes.
Letterbox mode scales (zooms
in on) a 4:3 image linearly (by the
same amount on all sides) to fill
a 16:9 display.
Letterbox is best suited for
viewing LaserDisc movies or
non-anamorphic DVDs on a
16:9 screen.
VirtualWide scales a 4:3 image
NON-linearly (more on the sides
than in the center) to fit a 16:9
screen.
On a 2.35:1 screen, the image is
centered between black bars on
either side.
