macOS High Sierra R9 280X weird display behaviour?

[GDMorry]

Ok so I have High Sierra running sweet on my GA-X58-UD3R (Rev 2.0 & FH Bios)

ATI Radeon R9 280X.

Everything seems to work ok **EXCEPT**

On boot I only get display through the Display Port (my centre monitor) left and right monitors (through DVI) do not display and are just blank!

I had just given up on getting it to work -=- but here's the kicker after waking from sleep ALL THREE displays now work

After a reboot it goes back to only the centre? after waking from sleep all 3 work again

Any ideas what I can do to fix so all three monitors work from boot?

Thanks very much. I will have a good look when I get in front of my PC.

I’ve Noted that it is NOT on sleep (HDD and Monitor) but more like hibernate eg. The whole PC is off but a power press wakes up The PC straight into the OS without bios and boot up etc.
