You will need to look into patching the AMD framebuffer kext. There are plenty of guides/info if you search for it.

hello rehabman thanks for the answer..credimi I read any word that related to the video card in question I tried millions of framebuffer only with el capitan I could have a connection hdmi but the images had continuous lag the only thing on which I have many doubts it concerns the extraction of the rom vbios that from windows with gpuz gives me error reading bios device not compatible with dpci manager once I give 1 lvdd 1 dmi and 1 vga another the result was 1 lvdd 3 serial port e1 vga I tried alternative methods for extract the vbios but I did not find anything that works. tonight I am attaching some files if someone can help me I would be grateful
