DP(DisplayPort) would be best.
For high resolutions you need either Dual-Link DVI-D or DP.
what's the difference between the 2?
Among other advantages, DP is capable of higher bitrate of 25.92 Gbit/s compared to DVI's 7.92 Gbit/s.
(Wikipedia has good info on them if you want to know more. I just refreshed my memory myself)
DP is a much newer standard and so I better in almost every way.
