Sierra Black Screen with Inject Nvidia disabled

[d112570]

I have a GTX 660 Ti, I read on the web that Nvidia needs to be disabled, but when I disabled I get black screen after loading. When I have it enabled I can log in, but only 1 of my monitors are active, the other 2 are offline.

I went from iMac 14,2 down to 13,2 since the original iMac 13,2 has a 660 for a graphic card. Did not solve any problems.

With Inject Nvidia disabled in the clover settings, Sierra is usable, but im missing my 2 monitors.

Sierra is fresh install, I copied the EFI folder from the USB stick to the Sierra EFI Drive.
Under 10.11.6 Everything works.

iMac 13,2 is correct for your system. Attach config.plist.

Thx for your help, I have replaced the config file and I still get black screen, I had to enable "Inject Nvidia" which works, but my GPU says I have 0 MB VRAM, and can't get my other 2 screens working. Same as before.

Do you have nvidia web drivers installed?

yes I do

Then that's you're problem. Change (inject nvidia) to false. And boot with nvda_drv=1.

It seems to work only once, I activated nvda_drv=1 and all was working. And after restart, i had black screen and needed to reactivate inject nvidia and log into sierra. Then I disabled inject nvidia again, restarted and everything was working, and after another restart I had black screen so I had to inject nvidia again to access sierra. It seems to work only after I disable inject nvidia and restart. 10.11.6 doesn't care what I do, it starts and works.
