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?

Rampage Dev Posted January 3, 2015 Share Posted January 3, 2015 Sounds like you are not using the correct boot flag. Please review: http://www.rampagedev.com/?page_id=276&page=3 Link to comment Share on other sites More sharing options...
jamiethemorris Posted January 6, 2015 Share Posted January 6, 2015 Otherwise, you could try flashing a different bios to it. The web drivers don't play well with certain cards. Link to comment Share on other sites More sharing options...

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... Link to comment Share on other sites More sharing options...
