I bought two Samsung 27 inch S27D590C curved monitors. I watched a youtube tutorial on how to connect to my macbook pro and bought the hdmi cables and hdmi to mini display adapter.....but I failed to notice that my macbook is a 2010 version and has no HDMI port... What can I do to connect the second display? Can I connect the two monitors to each other and do it that way? Can I use the USB drive or fireport to connect the second display? Any help would be awesome! Thanks!
