VESA Stereo
Encyclopedia
VESA Stereo is a liquid crystal shutter glasses interface standard by the Video Electronics Standards Association
(VESA) for stereoscopic
3D display
s. The system does not drive the glasses directly, instead providing a basic signal and power to be used by other electronics either inside the glasses or in an external unit.
The VESA Stereo connector has been extensively used in 3D accelerators
as well as 3D DLP TVs.
No special software is necessarily needed to create the stereo-sync signal as it can be created from the Vertical synchronization signal being fed to the monitor (if it is using RGB component video).
VESA
VESA is an international standards body for computer graphics founded in 1989 by NEC Home Electronics and eight other video display adapter manufacturers.VESA's initial goal was to produce a standard for 800×600 SVGA resolution video displays...

Stereoscopy
Stereoscopy refers to a technique for creating or enhancing the illusion of depth in an image by presenting two offset images separately to the left and right eye of the viewer. Both of these 2-D offset images are then combined in the brain to give the perception of 3-D depth...

3D display
A 3D display is any display device capable of conveying a stereoscopic perception of 3-D depth to the viewer. The basic requirement is to present offset images that are displayed separately to the left and right eye. Both of these 2-D offset images are then combined in the brain to give the...

Technical Details
The stereo-sync signal changes when the system is changing between showing images for the right eye and left eye. The signal is a TTL signal where the "high" state indicates the left eye should be exposed.No special software is necessarily needed to create the stereo-sync signal as it can be created from the Vertical synchronization signal being fed to the monitor (if it is using RGB component video).
