However, if a mode which does not
match the aspect ratio of the input
signal is selected, it may affect the
quality of viewing of the original
picture. Keep this in mind when
selecting the aspect ratio.

B If a normal (4:3) picture which was
not originally intended for wide-
screen viewing is projected onto a
wide screen, distortion may occur
around the edges of the picture so
that part of the picture is no longer
visible. Such programs should be
viewed in 4:3 mode to give proper
consideration to the aims and
intentions of the original program’s
creator.

RESIZING
This should normally be set to “ON”.
(This setting is only for signals
which have lower resolutions than
the LCD panels. Refer to page 56
for details.)
(This setting is only for signals

for details.)
ON
The pixel resolution of the input
signal is converted to the same
resolution as the LCD panels before
being projected. For signals with
lower resolutions, gaps in the pixels
are automatically interpolated into
the picture before it is projected.
This may sometimes cause
problems with the quality of the
picture.

OFF
The picture signal is projected at its
original resolution, with no pixel
conversion. The projected picture
will be smaller than normal, so
adjust the zoom setting or move the
projector forwards or backwards to
adjust the picture size if necessary.
If set to “OFF”, some features, such
as D.ZOOM (digital zoom),
keystone distortion correction or
INDEX WINDOW will not function.
