Basic Operation
Setting the ASPECT
This projector allows you to change the aspect ratio to match the type of
input signal. Pressing the ASPECT button will change the aspect ratio
according to the successive settings shown below.
(You can also change the aspect ratio by selecting the POSITION item in the
MAIN MENU and pressing ENTER.)
* “S4:3” or “S16:9” can be selected when NTSC, M-NTSC, PAL-M, PAL60,
525p and 525i signals are being input to the PT-L300U.
Illustrations for aspect ratio settings are shown on the next page. Refer to
this illustration for assistance in selecting a suitable aspect ratio.
About S1/S2 video signals:
BS1/S2 video signals are for 16:9 images and include a notification signal
when being played by devices such as a DVD player.
BWhen the projector is set to the “S1/S2” setting shown above, it will detect
those notification signals and automatically switch to the correct aspect
ratio for projection.
NOTE:
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.
BIf 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 program under copyright protection laws.
BIf 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 program’s creator.
BThe following signals have resolutions that are 16:9 image sizes. The aspect
ratios for these signals cannot be changed while being played because they
are already established. (Refer to page 61.)
HDTV60, HDTV50, 750p, WIDE 400/480/600/720/768
BImage sizes such as Cinema-Vision that project wider than the 16:9 ratio will
have narrow black fields at the top and bottom.
