No. ATI 5450 is completely in Sierra. You can try injecting ATY via a DSDT or try Inject EDID. Attach all files on [Guide] Enabling ATI Radeon HD 5450 thread.

@cyberdevs: Guess you might need to make your own framebuffer personality than, based on the physical port layout of your GPU.

@budafilms: R9 280X doesn't need iGPU in Sierra for basic functionality & acceleration (at least last time I checked, didn't update to 10.12.4 yet).

My Sapphire 7790 specs are:
1 x DVI-I
1 x DVI-D
1 x HDMI
1 x DisplayPort

which is working with the following settings:
Dual Link is set to 1, FB Name is set to Baladi, VRAM is set to 1024, Video Ports is se to 4, Load VBIOS is checked and finally Inject ATI is checked too.

Under Kernel and Kext Patches:

ATI Connectors Data is set to:

000400000403000000010300120403030004000004030000000101001102010100040000040300000001020021030202000400000403000000010400220504040004000004030000000105001000050500040000040300000001060020010606

and

ATI Connectors Patch is set to:

000800000400000000010300220503030004000004000000000101002103010200040000040000000001020012040201040000000400000000010400010204040400000004000000000105000000050600040000040000000001060020010605

and finally Ati Connectors Controller is set to 8000


and My HIS R9 390X are:
1 x DisplayPort 1.2 - 4096x2160
1 x HDMI - 4096x2160
2 x Dual-link DVI with HDCP - 2560x1600

The thing is I plugged the second display to DVI-I on my sapphire graphic adapter and it works but the HIS graphic adapter only has DVI-D.

So where do I go from here?

I found by mistake a way for not have enable IGPU and black screen with 280x on Sierra.

I made a partition in Sierra for test Final Cut X on El Capitan, because I read that work faster than Sierra.

I installed El Capitan. Set mobo NO IGPU, just PCIE.

I turn on the computear and in Clover Menu went to Sierra and no el Capitan. And I'm in without black screen.

I hope this going to be usefull.

FCP X is really faster on El Capitan, see my tests, by the way, wake from sleep also works with your config ?:
With: GTX 980 ti
OSX 10.11
Cinebench R15 = 112.44
LuxMark = 16244
BruceX 5K = 28s

OSX 10.12
Cinebench R15 = 110.08
LuxMark = 17300
BruceX 5K = 98s (although LuxMark scores better on 10.12 it did no translate to a better performance on FCP)

With RADEON 7950
OSX 10.11
Cinebench R15 = 110.95
LuxMark = 11248
BruceX 5K = 21s

OSX 10.12
Cinebench R15 = 109.12
LuxMark = 11207
BruceX 5K = 38s
