PNY has this, I guess it's new? But does it work with any cards that have a DVI?
 
Because 580's only have two DVI ports, but if I plugged this in, then I could have 4 monitors on it?

    Duplicating a single monitor image is pretty standard with Windows since XP. That is all this will do really. Take one screen and multiply it by four assuming your software will support four...

    What sort of port type is the single end? There are some rather different cabling setups in the professional line of cards. It's not outside the realm of possibility that the Quadro card this belongs to does push four independent displays. Problem is Quadro drivers suck for gaming.

    It's a single DVI, to quad-DVI.
     
    But yeah, being PNY, I bet it's for Quadro... And like you said, they ain't the best for gaming.
     
    Would be awesome if they made something like that to use 3+ monitors on one card though. Esp with Kepler if it's "so powerful, enough to run 3 monitors". That'd be nice.

    The problematic issue is port bandwidth. Dual-Link DVI caps out at roughly 5040x1050, so it can't do 5760x1080 at 60hz. This is where DP1.2 comes into play though with tons of port bandwidth. Something like the GTX570HD cards with a single DP1.2 port is handy. Matrox has a TH2G DP that can do triple screen from a single card, but it's ridiculously priced in a market where multi-head is enabled at a driver level now. The logical extension of that Zotac dual-HDMI adapter is have in that other thread would be a triple-head HDMI adapter like it for $60. At issue is the signal clock circuitry in those active adapters forces roughly a $20 per port cost to do it though. You'll never see a triple-head adapter for less than $60 in the future unless they can further cut production costs. That still beats the hell out of a Matrox TH2G DP for $350 though.
     
    The real answer would be for NVIDIA to see how SOftTH 2.0 works. Any port can push game content at any arbitrary resolution. The last thing on NVIDIA's mind is catering to a .00001% niche though.
