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

which have lower resolutions than
the LCD panels. Refer to page 52

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

will be smaller than normal, so
adjust the zoom setting or move the
projector forwards or backwards to
adjust the picture size if necessary.
