    Can your guys suggest me, How can i got 4K60Hz from this setup?

    By software or can i upgrade some of my components (GPU card or change to SST display).

    Thank you.

    In your Dell settings you have to enable MST; it's not on by default on the 2414 IIRC.

    The rest, I dunno unfortunately—I know it took a lot of random cable rearranging to get my 2415 to run as the main screen with my 7950.

    That is tricky one. I have a thread with MST hack but haven't done it myself for a few OS upgrades

    Yep, that won't be any problem at all, very popular screens here in combination with any GPU that sports a DP1.2 (like your GTX 680)

    yup that will work. I'm running dual of those on 4,1 - 5,1 flashed with a 980 (unflashed)
