When you say primary screen, do you mean the laptop's screen or an external monitor? I have two dvi monitors plugged in my docking station, but for some reason, I can't get the laptop's screen to transfer to the second external monitor.
Laptop screen and external DVI monitor work fine, but I would like to get both external monitors to work.
Has anyone had any luck with that?
I'm on 10.9.5 using the chamln guide with i7 nVidia graphics.
Thanks
