This is a late reply.
Found the Issue 2 months ago haha, it turns out my $80 HDMI Belkin Ultimate Series cables didn't have enough bandwidth. Went to Soniq Gold Cables and I now get a 60hz Picture at 4k.
For those buying into Samsung 4k TVs, make sure you buy HDMI cables with more than 18Gbit/s (HDMI 2.0)
Thanks for the help guys/gals.
