    Will the Geforce GTX 680 Mac Edition support 4K resolution over it's HDMI port?


    Good morning,
     
    The GTX 680 can support up to 4K on the HDMI port, specifically: 3840x2160 at 30Hz or 4096x2160 at 24Hz. However I will need to double check if this is the case with OSX, Windows there shouldn't be an issue. Please allow me a couple of hours to get confirmation and I will post back. If you have any other questions in the meantime please feel free to post in this thread.
     
    Thank you and have a nice day

    I got confirmation the HDMI port on the GTX 680 Mac edition in OSX is limited to 2560x1600. Sorry to say but no 4K support in OSX, if you have any other questions feel free to let me know.

    Thanks for checking.  I suppose that means that there is no 4K(60hz) support in OSX for Displayport MST either.

    I would say that your assumption is most probably correct.

    Trying to get some information on this port as well, most likely same limitations. Once I find i'll definitely post back here.

    OSX Mavericks must support 4K in some form or another since the new Mac Pro claims to have the functionality.    In anycase, I'd be much obliged if you'd tweek this fine card to have an HDMI 2 port that supports (60hz) 4K GPU for Mac Pro3,1 Early 2008.   I think 4K HDMI 2 UltraHDTVs are on the horizon.   Either that or create an adapter for this card that will allow for 60hz 4K to HDMI 2.

    The Display port is going to be limited to the same resolution, 2560x1600. I don't believe, at this time, there is going to be any modifications to the Mac Edition 680. If you have any other questions feel free to let us know.

    Hi Joey, can you please tell us why MST for DisplayPort on this card works in Windows but not OS X, especially considering this is a "mac" edition card?
    Why would running it in windows give it *more* features when it is a *mac* card?
    I have tested it in windows and MST does work -- you can drive a 4K display through the displayport connector via MST @ 60Hz.
    But on Mac OS X -- no dice.  Is it because NVidia does not want to update the drivers?
     
    It looks like if you want 4K on OS X you have to get a Quadro K5000. 
    Wow...that's ridiculous.  Thousands of dollars, all for a driver to enable something that is there already, but purposely crippled through software.

    Joey:
     
    Would you be good enough to test this card with a 4K display using the display port connector? It has been established that OSX Mavericks has full support for 4k resolution in the software, so we just need to know if there is driver level support for 4k from your Mac card. I doubt the specs will answer this; you have to just test it by connecting the card in a 2010 Mac pro to a 4K display via display port and see if the right resolution shows up on the monitor. The fact that the Quadro K5000 works at 4k in OSX suggests that this card should work as it is based on the same Nvidia chipset.
     
    I will buy this card in an instant if you can confirm this works (at 60Hz).

    I've tried the GTX 680 Mac Edition at 3840x2160 at 30Hz over HDMI and it seemed to work fine.
     
    I've read that the GTX 680 Mac Edition can support 60 Hz using an SST monitor like the Samsung U28D590D. The ASUS PB287Q is another SST monitor.

    Can anybody confirm that 4k monitors work at 60Hz over the DisplayPort? Just got the GTX 680 Mac Edition and it would be great with a 4k monitor (but not at 30Hz).
     
    It would be great to use an IPS monitor like ASUS PB279Q and prices are not quite reasonable but I like to know it works before buying...
     
    btw, I'm using OSX 10.10.

    I am also curious. My father bought a new 4k monitor and his 5770 only goes up to 2560 x 1600. He still has a really nice machine and I do not want to see him give away on the cheap if he can just upgrade the GPU....He uses the machine for photo and video editing, so gaming performance is not an issue.

    I have a Dell UP2715K monitor. It's a 5K monitor (requires two DisplayPort 1.2 cables) but I'm using it as a 4K monitor for now (using one DisplayPort 1.2 cable). SwitchResX says the dot clock is 533.25 MHz at 4K. I can't tell that the monitor is supposed to do 5K while I'm using it at 4K. You would have to use a particular test pattern to see any issue. I'm using Mac OS X 10.11.5 and a GTX 680 Mac Edition in a 2008 Mac Pro. I also have a Skylake Hackintosh with a EVGA GeForce GTX Titan X SC Gaming. I might replace that with a 1000 series card when they make one that has at least 12 GB like the Titan X.
     
    I've tried 5K on the Titan X in 10.11.4. There was a minor issue enabling it (have to power off and on the display after startup) so it's not super usable yet in Mac OS X (it can cause kernel panics). The 680 doesn't have dual DisplayPort so it can't do 5K. 5K works perfectly in Windows 10. The 5K features make the Dell UP2715K slow to wake from sleep (5 seconds?) even while doing 4K.
