Do you have WhateverGreen installed?

 

[firm112]

Yes latest version.. The build is based on your 18,3 Imac setup

Its one Displayport to a 4K monitor and two VGA to HDMI adapters

Hmm... WhateverGreen should enable all the ports...

Are all the DisplayPorts functional?

Btw, please update your profile with current CPU, motherboard, and GPU info.

I just have one and it works.. All hdmi ports works but when putting in the last hdmi cable it hangs and the fan spinns up black with screen
