Discreet graphics card is not working
I have a new Macbook Pro (Retina, 15-inch, Mid 2014). I am not able to use the discreet Nvidia graphics card. It isn't an option. I have attached three images showing my system. It clearly is only showing my Intel Iris 3000 integrated card. I just completed a complete reinstall of Yosemite, but it still has not fixed it. Do I need service? I have tried to reset the PRAM but am at a loss for what to do.
Thanks,
Blake
