5.1.3 Duty Cycle Ghosting
Duty Cycle is the adjustment of how long the lenses are open when an image is being displayed.
The default when using the 3D Emitter Port cable is 100 percent, meaning that the lenses are open for
the entire possible time. This is adjustable down to 10 percent of the possible open time. As the lenses
close more, everything gets darker.
Some displays do not make instantaneous transitions from the left frame to the right frame; instead
they will take time for an image to transition from one frame to another frame. For example, a CRT
(TV tube) monitor will have individual pixels that phosphoresce, or glow at their old brightness for
a little while before transitioning to their new brightness.

Duty cycle represents the fundamental trade-off between brightness and ghosting. Some displays
allow you to have it all and will not exhibit any ghosting or require the duty cycle to be reduced below
100 percent. Other displays will need to be upgraded or the user will need to find the ideal trade-off point.
For displays connected with the IR sensor or other custom cables, the ideal delay and duty cycle
information should already be transmitted; fine tuning should not be needed in ordinary situations.
