Oh god no! And I assume this isn't gonna happen anytime soon as anyone that can investigate the issue and has a 5K monitor also has a Nvidia card.

Let me know if I can be of any help on this.

@macnb: Exactly.

@bugsyraz: There are two things one could do: Investigate what real Macs are doing (e.g. IOReg dump on a Mac with attached 5K display) and try to mimick those Macs.

I guess the latter involves at least choosing the appropriate SMBIOS as well as injecting a special framebuffer personality. I guess iMac17,1 with framebuffer personality of M390 (which is a GCN 1.0 card like your 280X) should be a good match.

I don't know how much work people have already put into this topic, so it might be worth investigating it. Hackintosh + AMD graphics + 5K display isn't exactly common.

AMD GPUs can only drive two legacy connections (VGA, DVI, HDMI and passive DP). If you need more than that, you'll need to use an active DisplayPort adapter or a native DP display.

Btw, I guess you Asus GPU only has a single DP connector, so you can't drive 4 displays, no matter what you do.

I can help with providing this data. I have a 2013 Mac Pro that I can use connected with this 5K display. I just need help with doing IOreg dump. I only know the basics of installing hackintoshes.
