Hi. I have an intel hd630 and discrete amd hd6670 pciex. Bios is set to igfx as primary. Following guides I managed to make the system boot ok, even with a monitor attached to each graphics. But the one attached via vga to hd6670 is in black. Display preferences only show the intel igfx, but I see the hd6670 in system report. During installation of high Sierra both displays get signal and once in the SO they work fine toghether in mirror or separate display setup but hd6670 show flickering and strange colors. After multibeast installation and reboot hd6670 display is in black. I also give up of my gtx1060 and disconnected it, do you think is more easy with the Nvidia or should I keep trying with the hd6670. I need both graphics working because I have two monitors and one is only vga. Could connect both to hd6670 but I'm using igfx as primary because until now is the easiest for installing high Sierra with the inconvenient of the lack of vga port. How can I make hd6670 work fine as secondary graphics?*English is not my primary language.
