Reddit mentions of PNY NVIDIA NVS 510 2GB GDDR3 4-Mini DisplayPort Low Profile PCI-Express Video Card VCNVS510DP-PB

It looks like the Nvidia NVS 510 supports 4 4k monitors at 60hz via Display Port 1.2: http://www.nvidia.com/docs/IO/40049/NVS_510_DS_Oct12_NVIDIA_LR.pdf

It's around $330 on Amazon

Have a look into HDMI Distribution Amplifiers/Splitters, with these you can get multiple outputs from the one source. The ones we use at work are from Extron but there are others floating around after doing a quick google search and they seem relatively cheap

Edit: here is an example of what I mean

Ok this should be the last update I’m sorry haha, I’ve not bothered making a new comment as I’ve just been adding what I’ve found here

3 of there should do the trick

So for the digital signage wall we use at my office, we used a couple PNY NVS 810's, but that's fairly high price and since you only need 12 screens, I'd pick up a few NVS 510's. At 4 displays/~$150 I think this is probably the best deal you'll get.

What your looking for is Mosaic by NVIDIA and their Mid-tier NVS card. Just a few quality Mini-DP to HDMI cables set up the mosaic and it should be good to go. I personally run the NVS 810 on my home computer but I'm a freak and like having 8 displays.

Sure but it's twice the price. On sale.

You probably want the Quadro or the NVS workstation cards. We have these cards at work and they are specifically designed to drive multiple monitors.

There's also the older NVS 450, if you want to try your luck with liquidators:

Hey man... thank you so much!
We were actually just looking at the 970.
As an alternative, not sure if it is compatible though, do you think this would work... NVIDIA NVS 510 2GB GDDR3 4-Mini DisplayPort Low from http://www.amazon.com/PNY-DisplayPort-Profile-PCI-Express-VCNVS510DP-PB/dp/B009S2F268/ref=cm_cr_pr_product_top

I'm not sure if i have the confidence in the NVIDIA, but I dont know.

PS... i think you have some gold headed your way if thats okay.
