Joe,
  VMD only provides a single OpenGL graphics window. In order to
use passive stereo, your hardware will have to have support for this
feature, or you'll have to use a CAVE- or FreeVR-enabled version of
VMD to do this. I believe the NVidia graphics boards support what they
call "clone mode" stereo which should provide that feature. Another
option, which is a bit of a hack, is to make the VMD graphics window
full-screen and use the side-by-side stereo option, in which case you'll
probably want to direct the GUI to a different display (see the VMDGDISPLAY
environment variable discussed in the User's guide....)

Thanks,
  John Stone
