Hi Valeria,

To get CrystalEyes stereo on nVidia, you need to get one of their Quadro 
boards.

The nVidia "clone" mode isn't for stereo: it is for providing the same 
image on two outputs, not different images.

The easiest way to do stereo on two projectors is to get a video board 
that supports crystal eyes (e.g nVidia Quadro), and to buy a stereo 
"demultiplexer" that will split the crystal eyes signal into left and 
right video signals. The demultiplexer sold by cyviz is a popular one, 
but there are probably others out there, too.

The requirements for dual-projector stereo are as follows:

1) Software capable of quad-buffer stereo (e.g. VTK)
2) Any graphics card capable of quad-buffer stereo, with a crystal-eyes 
output connector
3) A demultiplexer
4) Two DLP projectors (LCD won't work, because they produce strongly 
polarized light)
5) Polarized shutters for the projectors

I hope this is what you were looking for.

- David
