I have a machine running with an RX 550 with 3 monitors (VGA-HDMI and DVI), I've used a GTX 650 also with 3 monitors in Mojave and Catalina running VGA, only this GT740 that isn't running VGA......
I'm not getting the 3 monitors on Catalina, when I boot from VGA it gives black screen, but HDMI and DVI work perfectly, how can I get the 3 monitors working, opencore.
