Black screen when booting with 3 monitors

[crnr]

Hello guys,

I'm using GTX 960 and 3 monitors (1DP + 2x HDMI).
I had some problems with installation, it worked for me just with using "NVWebDriverLibValFix.kext".

I did tied AGDPfix, not sure if this also helped but problem is next:
If I have all 3 monitors connected it will not boot up (black screen), if I take out monitor from DP port it will boot up then connecting it again I can use all 3 monitors.

I'm on iMac 14.2.

Any solution ?

Thanks

Hello,

There is additional issue. It also show black display when I wake it up from sleep mode.

I was able to see mouse cursor and notifications, but nothing else...

Thanks

Update: Sleep mode fixed, it wakes up but OS works very laggy. Will disable sleep for now.
