josephien Posted July 11, 2011 Share Posted July 11, 2011 Just informing you all, i have a hd4870 512mb that i flashed with a mac efi compatible bios when booting i have working monitor but as soon as the graphical interface of osx boots i loose the signal i (of course) tried the other dvi port with the same thing as a result so i wanted to try the vga signal to see if that one worked, as soon as i inserted the adaptor in the yellow port the dvi signal went trough and i had a working output... does anyone of you guys know if there's something i can do to make it work without the adaptor (dvi-vga) so i could only plug my dvi cable in as a second question i would like to know if it's possible to make the sound work over hdmi (with an adaptor dvi-hdmi) many thanks Link to comment https://www.insanelymac.com/forum/topic/262096-hd4870-512mb/ Share on other sites More sharing options...
