DisplayPort 1.1 or 1.2?

[vp49p3 216]

Hi--just got a 4k monitor.  The instructions say it runs best with a DisplayPort 1.2 so as to get 60hz and 3840 x 2160.  I have a two year old Titan Black.  I've looked everywhere but can't seem to find anything that tells me if I have 1.1 or 1.2.  Any help is appreciated.

I do not know this for a fact, but the Displayport 1.2 version was approved at the end of 2009, so I would be very surprised if your 'black' was 1.1. It could even be 1.3, since that was approved 15 Sept 2014. Further, my 3 year old GTX 680 has 1.2 AFAIK.

Odourboy--Thanks a lot!  I think my questions been answered.
