John,
I contacted our computer support people and they have few more minor
questions. I will appreciate if you could clarify some points. I am copy
pasting their email as they are not on the VMD forum and couldn't email
directly

Does the VMD software provide stereo support or are you relying on the NVida

Quadro to do the stereo?

Ie. Can I run the software on a standard GeForce code and produce side by

side output?

Many of the newer 3D displays are providing support for left/right,

top/bottom and interlacing modes, so if the application can get the images

out the display can reorder the pixels.

Thank you kindly,

Best Regards,
Vikas
