If anyone with sapphire r9 290x 4gb wants to test multiscreen with Baladi framebuffer patch in High Sierra, DVI's + HDMI should work, I guess with display port and bigger resolutions we're out of luck or we just need to experiment a lot to get it right...

  • injectAti = yes
  • RadeonDeinit = yes
  • FB name = Baladi
  • Video ports = 4
  • kexts to patch = AMD8000Controller

 

find:
