How to upgrade a Mac Pro 2012 graphic card using an HP display?
Happy Thanksgiving. I have a Mac Pro 2012 with a HP 30" display. I need to upgrade the graphics card so that I can install the latest Mac OS. I have the Apple article on graphics card recommendations. I also have an display adapter where the HP VGA plugs into it and then there are 2 cables coming out of the adapter: a USB and Mini Display Port. I think I did this awhile ago so I could plug my other Apple Cinema display into the stock graphics card VGA port to run both displays. I'm only using the HP now.
Q: none of the graphics cards that Apple is recommending have Mini Display ports, so I'm wondering if I. an detach my adapter and plug my HP Display's VGA into the graphic card's VGA port directly?
