• Answer:

  You have to plug in the monitors to the back of your computer, but be sure it actually has 3 places to plug it in. Take note you have to set up what you want as your main via computer options. It sounds like wheerever you plug the 3rd one in might not be functional. Please run a few tests for me. 1. Wherever it is plugged in but doesn't work, swap places with the other one and see if that works. If so, it could be the place where you plug it in is broken, it could also be a power supply issue where it just can't hold 3 up and running at a time. ... I'm not a IT. Thats really all I got other than google. You could ask on a microsoft website? Apple? either is fine. They all talk from experience.
