GraveDigger1454 Posted February 19, 2011 Share Posted February 19, 2011 Well, today seems to be a pretty bad day for my hacky ... My Gainward ATI HD 4870 1GB works very nice on the RGB and DVI Ports, but the HDMI gives me black screen on my TV and the TV doesn't show up in the Display settings ... Google / Forum Search didn't help. Here are the specs of my System: AMD Athlon X2 5200+ ASUS M3A78-CM 4GB DDR2-800 Mac OS 10.6.6 Legacy Kernel I don't use modified kexts, since the Card worked with PC EFI 10.5 and EVOenabler for HD4870. regards -GraveDigger Quote Link to comment https://www.insanelymac.com/forum/topic/248511-hd-4870-hdmi-output/ Share on other sites More sharing options...
