  My understanding is that on non-Quadro GPUs, the NVIDIA 3-D Vision tools
don't allow OpenGL applications to use stereo. I presume your machine
doesn't have a Quadro GPU in it, and you're only using the GeForce GTX 680?
I do find it somewhat odd that VMD is detecting stereo (note the "STEREO"
flag shown in the OpenGL renderer settings), even though your emitter
is not responding. My guess is again, that this is the known limitation
in the behavior of NVIDIA's 3-D Vision software. I can contact NVIDIA
and verify that the stereo driver limitation I described above
still exists if you like.
