      Mac Pro 5,1.

      2 Displays functioning for 9 years.

      1 Month ago 1 display ceased functioning: Checked cables: both work fine. periodically 2 displays are functioning then suddenly flips to 1 display only.

      Running Pro Tools 10 on system: could it be A. The Power Supply? B. The Graphics Card? C. Something else?

      Does anybody have any ideas? Thank you for your help in advance.

      Hi Sixer,


      Which graphics card do you have? Also which version of macOS are you running?
