My understanding of the situation (although I have not personally ever used VGL with a 3D TV or projector) is that 3D TV's/monitors can take an interleaved, side-by-side, or top-bottom image and convert it to stereo, which is why I added those three stereo modes to VGL. These modes half the resolution of the 3D image, however, since you're essentially packing two 3D images into the space of one 2D image. It is my understanding that 3D projectors support "full-frame" stereo using alternate frames at double the refresh, just like the quad-buffered output of a Quadro card, so I'm not sure why your Quadro couldn't drive one. To drive anything with "full-frame" stereo using VGL, you'll need quad buffering on the client, so it requires using vglclient and the VGL Transport rather than TurboVNC or another X proxy.
