the left eye and the right eye.
For details about the supported 3D image signal 
formats, see 3D supported signal on page 80.
To view 3D images:
Preparation: 
 Switching the 3D mode (such as 3D setting system)
of the player may be required when projecting 3D
images from the player supporting 3D display. Read
the user manual of the player for details.

9. If the contents are not projected correctly, repeat
step 1 to 5, press the W or X button to select 3D
FORMAT and switch 3D SYNC INVERT to ON.
Important:
 You cannot project the 3D content from the input
source LAN DISPLAY, USB DISPLAY, and USB
VIEWER.
 You can select the 3D setting also by using the 3D
button on the remote control. Press the 3D button to
select the setting and press the ENTER button.
 Even when the 3D option is set to AUTO   and a 3D
image is inputted from the HDMI1 or HDMI2
terminal, the 3D image is not displayed if the input
signal does not include the 3D identification signal.
In such a case, change the setting to SIDE BY SIDE
, TOP AND BOTTOM  , or FRAME SEQUENTIAL
 according to the format of the input signal.
 The signals listed in the table on page 80 can be
displayed in 3D format. You cannot view other
signals in 3D format even when you set 3D FORMAT
in the 3D menu to AUTO  , SIDE BY SIDE  , TOP
AND BOTTOM  , or FRAME SEQUENTIAL  .
 If the viewing distance is nearer than the
recommended distance, it will cause physical
discomfort and eye fatigue.
 Watch the contents in front of the screen, not at big
angle. If you are viewing the screen at big angle, you
may not be able to view 3D contents correctly.
 If you are not viewing 3D contents correctly, check
to see if the 3D glasses are powered on or
adequately charged. See the instruction manual of
the 3D glasses for more information.
 There are personal differences in viewing the 3D
images. For persons with myopia, hypermetropia,
astigmatism or left and right sights, please wear
glasses to correct them then wear the 3D glasses.
 The picture seems misplaced at the start of
projecting the 3D images, however, this is not a
malfunction.
 With the 3D FORMAT option set to to AUTO  , SIDE
BY SIDE  , TOP AND BOTTOM  , or FRAME
SEQUENTIAL  , 3D images displayed on the
projector appear darker. It is normal and does not
mean the projector is malfunctioning.
 The following features cannot be used when viewing
3D images on the projector:
 OVER SCAN and SHUTTER in the SIGNAL menu

 It may occur that the image may not be enough 3D
image because setting such as fluorescent lighting
may occur loss of synchronism of glasses.
 3D image may not appear on the screen depending
on the PC performance such as graphics board,
memory, or CPU.
 If DVD is run by 480p signals, 3D image may not be
displayed correctly depending on the DVD player.
 When 3D image is projected on the screen in 120Hz
or using certain type of playback software of PC, the
image may not appear on the screen.
 3D image may not be displayed properly depending
on the settings, functions, or manner of connection
of the DVD player or Blu-ray player.Caution:
Notes on danger to public health during watching 
3D image
 Stop viewing the 3D image immediately if you feel
tired, discomfort, or any other abnormality. It may
cause you to feel unwell if continuing to watch the
3D image in such cases. Please take the necessary
rest, do not continue watch the 3D image for a long
time. Stop using the 3D glasses if you can clearly
see double images when viewing 3D content.
Prolonged use may cause eyesight fatigue.
 The following people need to refrain from use as with
2D image.
 a photosensitive patient
 a patient with heart disease
 a person in poor physical condition
 a sleepy person
 a very tired person
 a drunk person
 children
 When watching 3D movies, take an appropriate
break after watching a movie. When watching 3D
content on interactive devices such as 3D games or
computers, take an appropriate break every 30-60
minutes. Prolonged use may cause eyesight fatigue.
 When you feel uncomfortable, stop viewing 3D
images and playing 3D games until you are restored.
If necessary, consult a doctor. Also, stop driving a
car until you are restored (for about 2 hours). The
period to restore varies with the individual.
 As a guide, 3D glasses should not be used by
children younger than 5 - 6 years old. As it is difficult
to judge younger children’s reactions to fatigue or
discomfort, their physical condition may deteriorate
suddenly. When this product is being used by a
child, the parent or guardian should check to ensure
that the child’s eyes are not becoming tired.
 When viewing the pictures that roll over and shake
or many dynamic pictures, if you feel uncomfortable,
please look at another place.
 When viewing contents with movements such as
rotation, or horizontal or vertical oscillation, you may
feel as if you are actually moving. If such a feeling
results in discomfort, look away from the screen.
 When using the 3D glasses, be careful not to strike
the screen or other people by mistake. As the
images are in 3D, you may mistake the distance
from the screen, causing to strike the screen which
may result in injury. When using the 3D glasses, do
not place breakable objects near the glasses. You
may move by mistaking the 3D objects you are
viewing as the real objects, causing damages to
surrounding objects that may lead to injury.
 When using the 3D glasses, make sure your eyes are
on an approximate horizontal level. If you suffer from
myopia (short sightedness), hyperopia (far-
sightedness), astigmatism, or have eyesight
differences between the left and right eyes, please
use corrective glasses or other such methods to
correct your eyesight before putting on the 3D
glasses.
 When you view the 3D images, keep a distance from
the screen of about three times the effective height
of the screen.
