there are a bunch of new ATI and nvidia cards our there that claim to do quad buffered stereo, but that don't have a 3 pin connector. i don't understand what the point is- can someone tell me why you would ever use quad buffered stereo without the ability to synch the signals? if you're going to use an external dongle, you'll get interleaved z-buffer based stereo, in which case you don't need quad buffering. so what's going on here? why don't all quad buffered cards come with a 3 pin DIN connector for shutter glasses? | ||

You can use pin-9 on VGA out (so coled DCC) for perfect synchronization without the 3-pin connector. There exist pass thru VGA cables with the din-3 connector adders ... | ||

ok, so you could buy a cheap quad buffered card, hook up one of those pass through cables, and you'd get real full screen, non-interlaced stereo? thanks for your reply, kevin | ||

Kevin: Yes for games. No for profesional applications (they take ful control of precise stereo output based on OpenGL - this is not avaliable in the game drivers). | ||

My $.02 on this. Quad buffered page flipped stereo is a name that is bandied about by many people for defining many things. It is mostly associated with professional stereo as opposed to consumer or other stereo mechanisms. By definition quad buffered page flipped stereo means you have at least 4 buffers for rendering the view being displayed. Left, Right for both front and back buffers. These are generally accepted to be full resolution each and are swapped left to right on every VSYNC and front to back on application flip upon completion of scene render. So some examples: NVIDIA's quadro stereo is quad buffered page flipped. E-Dim's synch doubled stereo almost qualifies, but is 1/2 resolution. NVIDIA's consumer stereo driver is quad buffered page flipped. It's full resolution, H/W flipped and uses at least 4 buffers. To the point above, there are many ways to trigger the glasses on a Left to Right flip, not just by a direct H/W line as with the 3Pin connector. Those other ways do not negate the fact that it is still quad buffered page flipped stereo. - StereoGamer | ||

So In order to run proffessional aplications that use quad buffered open gl stereo you need a card with a 3 pin connecter??? And it would not work with a stereo enabler connector??? | ||

Paul: No. Several Quadro cards do not have the connector and it worsk (by the help of DCC VGA pass throug dongle) ... |
