MJ120394 Posted January 3, 2015 Share Posted January 3, 2015 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?

You need the latest Nvidia Web Driver - 343.02.01f01 - enabled HDMI but limited to 1080P. DVI - HDMI works but limited to 4k 30hz. The previous Nvidia Web Driver - 343.01.02f03 - HDMI port did not work. DVI - HDMI had 4k60Hz. Tested that in 10.10.1 with GTX 980 in LG 49UB8500. I don't have any displayport screens to test, so I can't tell...
