Hi all! I just recently got my EVGA SC ACX GTX 980 and installed Yosemite as well. After a successful install, I installed the NVIDIA web drivers and put the graphics card on my board, but on either HDMI or Displayport, I get a signal loss. Yet, when I use a DVI cable, it works fine. From what I've been reading, many people have been getting issues with getting both to work. I have used all three of the drivers (f01-f03) and still get the same results. What exactly do I need to do in order to get both HDMI and displayport to work properly?
