That is possible. On the other hand, I do not see it as a necessarily bad or evil thing to do, because every manufacturer who can make a stereoscopic gizmo seems to have the compulsion to develop a proprietary electrical interface and protocol for it as well. So this could force a bit of sanity in the market. If your gadget needs something special, build a decoder/converter in it and do not expect others to do your job. As a user, I personally prefer devices that use standard protocols/connections, because then I know that it will likely work with other software than the vendor-provided driver that will be likely unsupported and not working on new Windows, new Linux kernel, X or whatever. > The thing is that from my view it should not be a big deal for nvidia > to include a feature for the new glasses and usb sync technology to > work with quad buffer off a quadro fx > The ability to use lcd glasses with LCD monitors for desltop stereo is > a big deal, i dont recall its been doen before (other than usless lcd > glasses free technology that is not worth the cost).

Shutter glasses with LCDs are a problem due to latencies of the LCD and polarization issues (LCD has a polarizer in front of it). It is not really a graphic card vendor problem - you need special LCD screen to be able to use shutter glasses with it. Re USB sync - what for? To need a special driver and occupy an extra port for the glasses? The VGA connector has everything you need for this, even 5V power on it and the stereo signal circuitry is there already on Nvidia cards. The only thing you would need is a cable splitter with a connector for the glasses. > As far as laptops go, DELL sell a range of workstation laptops, that > have built in Quadro FX vga cards and they support quad buffer stereo. > If you use lcd glasses on the external vga port that takes the sync > from there, there stereocpic works fine.

That is possible, but these are really huge bricks, if I remember right. I would also hesitate buying DELL machine because of past experience with their "service", but that is another discussion.
