A:Answer No, display ports don't have version numbers, but the difference is in the cable. If you use anything else besides the display port, the monitor won't play in true 4k. Display port will do 4k at 60 hertz, hdmi does it at 30 hertz. So, just get a display port cable, and be done with it. Just make sure your video card has a display port, or your wasting your time
