TROUBLESHOOTING  WHEN USING 3D MODE
TROUBLESHOOTING WHEN USING 3D MODE
I can see a swirling oil-like pattern on the monitor when the monitor is turned off.
yThis is caused by the interference of external light in the air layer between the LCD surface and 3D filter.
    The pattern becomes almost invisible when you turn on the power again.
I cannot see 3D image properly
If you are not using the glasses 
provided with the monitor,
yWhen you view 3D images with this monitor, it is very important 
that you use the glasses provided with the monitor. The glasses are 
designed to compensate optically for the 3D filter attached to the 
surface of the monitor. If you wear third-party glasses, you may not 
see 3D images properly on the monitor.
If you view 3D images outside the 
optimal viewing angle or distance,
yThe optimal viewing angle of the monitor is 12° in vertical direction 
while 80° in horizontal direction; the optimal viewing distance is 
between 50 cm to 90 cm from the monitor. 
 When you view 3D images outside the optimal viewing angle or 
viewing distance, the images may look overlapped or not be displayed 
properly in 3D.
If you have not set the resolution,  
yPlease set the resolution of the monitor to the maximum (1920 x 
1080 @ 60 Hz) in the display settings. The 3D software may not work 
properly if the resolution is not set to the maximum.
If the images that your left and right 
eyes see are reversed,
yThe stripe images in the odd-numbered lines are the ones that your 
right eye sees on the monitor. If you only see the stripe images, not 
3D images, set the images for your right eye to be displayed in the 
odd-numbered lines by changing the player or viewer option of the 3D 
software.
I cannot see 3D but only 2D images.  
yThis monitor works both in 2D and 3D mode. You can view a video in 
3D if it is made in 3D. If you try to view 2D images in 3D, they might 
not be displayed properly or you may experience poor picture quality.
If the ‘TriDef 3D’ couldn’t work 
properly
yThe minimum system requirements on PC to run the ‘TriDef 3D’ :

PRECAUTIONS TO TAKE WHEN VIEWING 3D IMAGES
PRECAUTIONS TO TAKE WHEN VIEWING 3D 
IMAGES
1  If you view images in the 3D mode for a long period of time (playing games, watching movies etc.), you 
may feel dizzy. We strongly recommend you to take a rest after one hour of viewing 3D. (The time of 
experiencing dizziness varies depending on the individual.)
2  Please view 3D images at the optimal viewing angle and at the recommended distance from the 
product. Otherwise, 3D images may appear to be overlapped or may not be displayed properly.
3  If you view 3D images too closely for a long period of time, this may result in dizziness or blurred vision. 
Please use the device at the recommended distance.
4  If you are pregnant, elderly or have heart problems, we recommend that you do not view 3D images. 
This is because the 3D images can cause disorientation and confusion.
5  3D images can also cause nausea or vomiting for users under the influence of alcohol. In this situation, 
please do not view 3D images.
6  Parents/guardians should monitor children’s viewing of 3D images because they may not be used to the 
3D viewing experience and lack knowledge on how to handle potential risks.
7  Do not use the 3D glasses as regular glasses, sunglasses or goggles. This may cause your vision to 
worsen.
8  Do not keep the 3D glasses in an extremely hot or cold place. This may the shape of the glasses to 
change and become damaged. Do not use the 3D glasses if they are damaged because this may cause 
your vision to worsen, or you may experience dizzin.
9  The lenses of the 3D glasses (polarizing film) are easily scratched. Use a soft clean cloth when cleaning 
them. Do not use any chemical cleaning products on the glasse.
CAUTION

 ySome users may have a seizure or other abnormal symptoms when they are exposed to a 
flashing light or particular pattern in a video game or movie. If anyone in your family has a history 
of epilepsy or has ever experienced any kind of seizure, please consult with your doctor before 
viewing 3D images. If you exhibit any of the symptoms listed below when viewing 3D images, 
please stop viewing immediately and consult with your doctor even if you do not have previous 
medical problems of this nature.

disorientation and wrong state.
To prevent a photosensitivity seizure, please follow the instructions below.
