Basic Operation
S4:3
The size of the input signal is
compressed to 75% and projected.
(This is useful for projecting a
picture with a 4:3 aspect ratio onto a
16:9 screen.)
When a 4:3
signal is being
input
[
AUTO
(S-VIDEO only)
When an S1 video signal is input to
the S-VIDEO terminal, the aspect
ratio is changed automatically to
project a 16:9 picture.
4:3
The input signal is projected without
change.
16:9
The picture is compressed to a ratio
of 16:9 and projected.

quality will deteriorate, and the harder it
will become to achieve a good level of
focus. To obtain the best picture quality,
set up the projector and screen in such
a way that the amount of keystone
correction required is as minimal as
possible.
BThe picture size will also change
when correction of keystone
distortion is carried out.
BThe range of keystone correction
varies depending on the type of
signal being input. If you make an
adjustment that is outside the
allowable range, the setting will not
be changed. In addition, if the input
signal changes after keystone
correction has been carried out, the
correction setting may be cancelled.
This indicates that the current
correction setting exceeds the
allowable range for the new input
signal.
BIf you correct both vertical and
horizontal keystone distortion at the
same time, the allowable range of
keystone correction becomes
smaller. If you make an adjustment
that is outside the allowable range,
the setting will not be changed.
OSD POSITION
Press the Ior Hbuttons to move
the OSD position.
ASPECT
This setting is only valid for an S-
VIDEO/VIDEO signal and a YP
BPR
signal in 525i (480i), 525p (480p)
and 625i format.

NOTE:
BS1 video signals
S1 video signals are a type of video
signal with an aspect ratio of 16:9
which include a detector signal. This
detector signal is output by some
sources such as wide-vision video
decks. If the AUTO setting above is
selected, this projector will recognise
the detector signal and automatically
switch the aspect ratio to 16:9 in
order to project the picture.
BThis projector is equipped with an
aspect ratio selection function.
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 using this projector in places
such as cafes or hotels with the
aim of displaying programmes for
viewing for a commercial purpose
or for public presentation, note
that if the aspect ratio (16:9)
selection function is used to
change the aspect ratio of the
screen picture, you may be
infringing the rights of the original
copyright owner for that
programme under copyright
protection laws.
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
programmes should be viewed in
4:3 mode to give proper
consideration to the aims and
intentions of the original
programme’s creator. B
When a VGA60 or 525p RGB
signal is being input, select the
signal in accordance with the
input signal.
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  63
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) or
keystone distortion correction will
not function.
AUTO SETUP
This item functions in the same way
as the AUTO SETUP button on the
remote control unit. (page  16)
FRAME LOCK 
If the picture ’s condition is bad while
a RGB moving picture signal is
projected, set the FRAME LOCK to
“ ON ”. Refer to page  63 on
compatible RGB signals.
