What kind of connectors and how many does your card have?
My Gigabyte R9 280x has two MiniDP, 1 HDMI, 1 DVI-I and 1 DVI-D (both Dual-Link) connectors.
Also post a radeon_bios_decode post of your card. Maybe i can than make a working FB-patch for your card, cause maybe your HotPlugID's are different from my card and thats why my post above didn't work.
This is the radeon_bios_decode of my GIGABYTE Card:
