Q: 3 4k monitors on mac pro not working

I have 3

Samsung - UD590 Series 28" LED 4K

monitors and i have 2 connected via the mini display port to HDMI and one connected via the HDMI port, apple says this configuration should work but i can't get the 3rd screen to ever fire up, i have tested all three screens and only two of them seem to work at any given time, Use multiple displays with your Mac Pro (Late 2013) - Apple Support, any help would be much appreciated! Thanks!

Mac Pro
