scales the source
active image hori-
zontally, so that a

correct aspect ratio
when using an an-

Native
Select Native to
display the source
signal in its native
resolution, centered
in the display area
with no re-sizing or
overscan.
This means, for
example, that 720p
HDTV programs will
display with unused
pixels on all sides:
320 on the left and
right sides and 180
above and below.
With SDTV and
EDTV sources, the
H9080FD scales the
image horizontally to
achieve a 16:9 as-
pect ratio.
