I have dual GeForce GTX 680M graphics cards in my alienware laptop and have only one displayport 1.2 output. On the NVIDIA site the most detail I found about the 680M cards is that it supports up to 4 displays and a max digital (displayport 1.2) resolution of 4096x2160 @ 60Hz.
Is this referring to one monitor? Would I only be able to have 4 displays through the displayport if they are 1080p displays because of the limitation of bandwidth? From the specs I see each 680M can do one 4k display @ 60Hz yet I have only one displayport 1.2 output on my laptop. Am I stuck with a max of one 4k display @ 60Hz then? Could I have two 4k displays at 30Hz through the displayport? How many displays can I have which support MST (Multi Stream Transport) in which they can be daisy chained from one displayport 1.2 output? I found on the NVIDIA's site the following, "Support for 4k tiled MST displays requires 326.19 driver or later." I currently have driver 344... so that won't be an issue. So before I buy three 4K monitors ($$$$) I would love to know how many 4k monitors my dual GTX 680M setup can handle across one displayport 1.2 output and of course the maximum size of the monitors. Is there a super awesome extremely detailed chart out there I could reference? Any help is much appreciated.
