stereo 3d driver with multiple gpu fail with quad buffered directx

I’ve developed a stereoscopic visualization system using the nvidia stereo3d. On my alienware laptop with geforce gtx 780M chipset, I’m able to visualize stereo output using the shutter glasses using either the nvidia stereo api or the directx output (which my understanding was that it invokes the nvidia api).
On a separate workstation with (3) Titan geforce cards, I can only use the nvidia 3d api. The directx output fails to invoke the underlying nvidia stereo api.
Is this a nvidia driver directx problem. Any ideas on how to troubleshoot this issue?
Both systems running win10 with latest updates along with latest nvidia drivers.
