    I'm wondering about a 4K display (and why not two of them!) on my mid 2012 Mac Pro.
    1) I know that an nVidia GTX 750 or 960 or 970 or 980 will handle one of those on my config... and what about two 4k displys?
    2) Will I be able to set display's brightness and contrast from Mac OS as one can do with any other Apple-made display? I can't do that on my DELL U2312HM...
    3) If I buy a conventional PC card will it work out of the box except for booting logos and EFI stuff? Using a secondary low-demanding Apple video card will solve this issue right?
    4) Will I need an external power supply? (I have read the thread... but I is there is no absolute conclusion?)
    5) Is there something I missing or I will to face to take into account with a PC card or 4K displays?

    TIA ;)

    GTX680 and ATI 7950's are a good option both are easy to flash for boot screen's and both work out of the box!

    GTX 680 has only one DisplayPort, so not possible to use two 4K display's.

    May be it's possible if the 2nd screen only display at 4k 30Hz.

    The HDMI port delivers 4K@30Hz. I am not sure why you would need 2x4K displays. I have a single 40" 4K display which is quite enough screen real estate & pixels for me:)

    Will a 2012 Mac Pro take full benefit from a 980Ti-6GB?
    Should I go for a 960-4GB or a 980-4GB instead?

    What do you suggest?

    The 960 (GM206) is the only full hardware HEVC/H265 decoding enabled for hardware decoding 4K movies and natively supporting HDCP 2.2 content over HDMI 2.0... while 970, 980 should support HEVC video encoding only.
