My Profile had included all the Hacks that I have but just changed it to my Hack 2 in my Signature.
My Signature contains some more detailed specifics.

The Sapphire HD7770 has 4 ports: 2x Mini-DP, HDMI and DVI-D.
I am using Mini-DP to DP cable to a Dell 4K monitor (S2721QS).
I have tried all different connectors and makes no difference.
