I have a Mac Pro 2013. I already have two 4k monitors now connected to
the HDMI port (Bus 0) a thunderbolt port with a TB->HDMI adapter (Bus 1) Before I simply buy a third monitor and adapter, is it as easy as that?
Do I just plug another adapter into the last BUS that isn't being used? (I understand to separate the monitors on different buses.)
FYI, I tried a 3rd monitor that wasn't 4k and it didn't fire up/get recognized. I read somewhere on Apple's site that once you have one 4K monitor connected you need all of them to be 4K.
