I don’t recall you mentioning a display.
Whatever you choose needs a cable, and video ports of the correct flavor on the GPU.
Don’t assume anything, double check the GPU output ports.
Spinning a web of terror, LOL. :-)

Tangent alert...
A couple Blendtuts for later reference.

my display is my 65” flat screen in my living room... mouse table is comfortably level with the arm rest of the couch!! HDMI for years!! The only problem is I never really knew how to match the resolution so to date, I am always resizing the PC screen to fit right on the flat screen! unless I go to full screen then all is good.
