Monster Vision MAX 3D - Basics of Fine Tuning

5.1 BASICS OF FINE TUNING
The basis of 3D depth perception is seeing slightly different images in each eye. Both movie theaters
and home entertainment systems work together with 3D eyewear to enable you to look at a flat screen,
see different images in the left and right eyes, and experience the illusion of depth.
5.1.1 Shutter Lenses
All 3D shutter glasses start with an alternating frame display which alternates displaying frames for
the left eye and frames for the right eye. This is achieved by blocking the light of the left frames from
reaching the right eye, and vice-versa.
While viewing through the eyewear, each eye is actually receiving every other frame. With the
frames sent in rapid progression, the brain reassembles these images to form a moving picture;
in the case of 3D a separate moving picture is viewed in each eye.

Active shutter lenses contain liquid crystal displays. Each lens alternates from clear-to-dark every
other frame, thus making the left frames look dark to the right eye and vice-versa. The name shutter
lenses is a legacy of the first shutter glasses which used mechanical shutters like those found on a
camera or projector.
Many televisions with the VESA 1997.11 stereoscopic connector (the 3D emitter) behave almost
identically to this timing. When attaching your MAX 3D Transmitter to the back of these TVs, the
default settings for delay and duty cycle work perfectly and performance is already perfectly tuned.
Mitsubishi 3D DLP TV has a 3D Emitter Port in the back (left) and alternating frame 3D image in the
front (right) that match the timing described here. The MAX 3D Transmitter will work out-of-the box
for this case with no performance tuning.
