Black Screen with MacPro 6,1 or iMac 15 or iMac 17 System Definition

Sierra 10.12.6
Definitions 17.1
Lenovo Thinkcentre M800 i5-6400
Gigabyte GeForce GTX 750 Ti (2 x HDMI + 1 x DP + DVI)
nVidia latest Web Drivers 378.05.05.25f01
Dell P2416D 2K monitor


Using Lilu.kext & NvidiaGraphicsFixup.kext

I can only get display working on a middle HDMI, other HDMI & DP produce NO signal, did not try DVI (so no multi-monitor possible)
Any idea how to get all ports to output? I really only need DP to also work...

EDIT
Turned out that I had to set Video in BIOS to be PEG, as Auto was giving the very problem
Once set, DP works (as well as HDMI, DVI untested)

Hi,
I am having this black screen problem.
The only problem in changing the definition is that I use core 2 due which evaluate to mac 10.1
GTX 650 works with nv_disable.
P.S. don't want nvidia web drivers, it should be native supported.
 
Thank you shilohh

Lilu.kext & NvidiaGraphicsFixup.kext fixed "Black Screen" finally ;)

Thx
 
I'm in the same boat. I've added Lilu.kext and NvidiaGraphicsFixup.kext. But I'm not getting any obvious errors. Screen shot attached. thanks!

Also black screen here. Until Sierra 10.12.6 native graphics support. What can be wrong?
 
I'm getting blank screen as well after I upgraded to macOS high sierra 10.13.0. The fix here worked when I upgraded from 10.12.4 to 10.12.5. Then when I upgraded to 10.12.6 I didn't have blank screen at all.
After I upgraded to 10.13.0, I got blank screen and I applied the fix in the first post, but I ended with stuck at apple logo. I had to restore from local snapshot.

Is this fix working with 10.13.0 as well?

Any help would be appreciated

How exactly did you use the Lilu.kext and NvidiaGraphicsFixup.kext? I tried it and got me stuck at apple logo

i put kexts in Clover EFI/Clover/kexts/10.13 and that's all
Now i'm using SMBIOS iMac15,1
 
If you are booting to a black screen after installing new Lilu and intelgraphicsfixup kexts then make sure screen sharing is enabled and the rebuild the Kernal Cache. That has worked for me a couple of times.

Code:
sudo touch /System/Library/Extensions && sudo kextcache -u /
