My 5,1 MP has been working great. The 7950 has done an excellent job in FCPX, sticking with 1920x1080 resolution, using DVI or HDMI ports, what my trusty Viewsonic display supported. Just recently I got the itch to move to 4K and ordered a new monitor. The Dell P2417Q has arrived and it is very nice with all the details I could never see before. While trying to achieve 4K @60Hz I discovered that neither of the display ports are actually working. I got this HD 7950 off eBay a couple of years back, and it is just an average joe card flashed by some dude, not the official Sapphire one. Is there a way to enable the display ports? Also, would it make more sense to get a GTX Pascal now that drivers are available for OS X instead of messing with this older card. Your advice would be appreciated.
