You can enjoy 3D Content with this projector.
In order to watch 3D Content, you need to have the following items:
1. Field-sequential 3D video contents
2. DLP Link active electronic shutter glasses
(Field-sequential: The system which displays alternately the image for the left eye and the right eye.)
Play the field-sequential 3D video contents on a computer or DVD player, and then, connect the cable with the 
projector.
Go to the DISPLAY menu, then, set the 3D option to On.
Put on the electronic shutter glasses to watch the contents.
If the contents are not projected correctly, go to the DISPLAY menu, and switch the order of the image setting to 3D 
Sync.
• 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 electronic shutter glasses are powered on or adequately 
charged. See the instruction manual of the electronic shutter glasses for more information.
• With the 3D option set to On, contents 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 contents on the projector:
• Magnify
•Setting
• Brightness
•Contrast
• Color
•Tint
• Sharpness
• BrilliantColor™
• Color Temperature
• 3D Color Management.
• 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.
