VESA Stereo is a liquid crystal shutter glasses interface standard by the Video Electronics Standards Association (VESA) for stereoscopic 3D displays. 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.
|Type||stereoscopic shutter glasses connector|
|Max. voltage||5 V|
|Max. current||750 mA|
|Pins from left to right 2,3,1|
|Pin 1||5v(p)||5v (750ma)|
|Pin 3||Sync||Stereo Sync (TTL)|
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).
