My understanding was that it could run 4096x2160 resolution via DisplayPort @ 60Hz.
I'm I wrong in believing that these cards can run 4K at 60hz on the 5.1?
I was using a GTX 680 with a Dell P2715Q and everything worked fine. The image quality was a huge step forward from my old Dell 3007WFP-HC. I run the monitor at 3200x1800 resolution. Anything higher and I had to strain to see some stuff.
Hi Pastrychef. Are you running 3200x1800 at 60hz ? Are you using the DisplayPort to connect to your Mac Pro? The fonts are not difficult to read? Thanks
Just be aware that KEPLER cards don't have boot screens on 4K SST and 5K. It is thus more like running an unflashed card.
I have a GTX760 on its way back to me for exactly that reason right now.
Only the newer Maxwell cards can do that little magic trick.

Thanks for your reply. I've read that some people get lag on the Dell @ 30Hz 4K. Are you seeing anything like that? Are you happy with monitor? or is something like the Samsung worth the extra bucks?
So Kepler cards can still display at 4K but without a boot screen even if the card is flashed?
Hello.
Yes. I'm running at 3200x1800@60Hz via DisplayPort. I don't have a problem reading things at this resolution but everyone's eyes are different...
My flashed GTX 680 cards can display boot screen at 4K only on HDMI.
When connected via DisplayPort, it doesn't show boot screen.
I have never used it at 30Hz. I have only used it at 60Hz. I have not noticed any lag.
Thanks for clarifying. I've been thinking about the 4K Dell monitor. I am using a Mac Edition 680 GTX card. Enjoy the week ahead.
Over HDMI, do you notice any ringing or edge effects along lines and borders? Not in video, but in the GUI or applications.
Other than to test whether or not HDMI gave me a boot screen, I have never used HDMI for any length of time. I will try it out a little later and report back.
I used the monitor via HDMI for about 45 minutes and didn't notice any ringing or edge effects. Everything looked as good as when using Display Port. However, there was a very noticeable lag with the mouse pointer which I'm assuming is due to the 30Hz limitation of HDMI.
Oh interesting. I ask because of this article that says 4K@60Hz is possible with Kepler, and people have confirmed with the GTX 680 specifically (there is color information lost in order to stay within the HDMI 1.4 bandwidth limitations). But I guess OS X itself is limiting 4K HDMI to 30Hz, so maybe that's a Windows option.
Wow. Interesting. Based on the linked article, it appears that version R340 of the driver is needed in Windows along with a display that uses "chroma subsampling".
