Argh, nothing like a monopoly jacking up prices artificially :( It has been known that the hw can do it even on generic GeForces and that NVIDIA was intentionally disabling it - there is little need for their overpriced Quadros if your HMD can do only 800x600 anyway. Thanks for confirming this, though. The internet is suspiciously mum about this. > The caveat with using quad-buffered mode is that Apple's machines don't > include any means of signalling the shutter glasses or stereo goggles, > so you're back to using something like the Stereographics blue-line > detector box to perform the signal extraction. It doesn't work through the VGA pin 13 DDC signal? That is what NVIDIA used to use on consumer cards before and it is an option on Quadros too.
