Why not use DP 1.2? Every decent GPU probably has at least 1 of those. But the new monitors will probably have at least one HDMI 2.0, like the Asus 4k IPS g sync monitor, so perhaps keep an eye on those?
Thanks, I've been waiting on the Asus, I haven't seen an expected release date as of yet.
On DP 1.2, that was a mistake I made in my research, I didn't realize a single DP would support 4k at at 60Hz
