== Stereoscopic Video == 

 In this paragraph: 

 "One channel with alternating left/right frames for each eye, using LCD shutter glasses which read the frame sync from the VGA Display Data Channel to alternately cover each eye, so the appropriate eye sees the correct frame. This method is most common in computer virtual reality applications such as in a Cave Automatic Virtual Environment, but reduces the effective video framerate to one-half of normal (for example, from 120Hz to 60Hz)." 

 Stereoscopic video applies to much more than VGA, and furthermore, it is unlikely that the frame sync comes from the Data Display Channel.  Please provide details and/or a credible reference, or this will be changed.
