I am trying to install sierra but I haven't been able to get multiple monitors working. Only one slot on my graphics card will work.
My hardware is:
Mother board - Gigabyte Z77X-UD5H
CPU - 3.39 GHz Intel Core i5
Memory - 32 GB
Graphics - EVGA Geforce GT 640
Does anyone have any idea what the issue is? I have tried all the graphics options in multibeast.

I have tried all the graphics options in multibeast.

The GT 640 works out of the box with full acceleration with native drivers and NO injection.

No issues here with single, dual or triple monitor setup.

Okay. I tried without injecting graphics but not with that definition. I will try that when I get a chance.

Okay, I got the monitors working.
Multibeast Configuration:
Clover v2.3k r3766 UEFI Boot Mode
Audio: Realtek ALCxxx - ALC898
Disk: 3rd Party SATA
Misc: FakeSMC v6.21-311-g2958f55.1723
Misc: FakeSMC Plugins v6.21-311-g2958f55.1723
Misc: FakeSMC HWMonitor Application v6.21-311-g2958f55.1723
Network: IntelMausiEthernet v2.2.0
Graphics: Make sure no options are on!
SSDT Options: Sandy Bridge Core i5
System Definition: iMac14,2

It still didn't work with these definitions. I discovered that Multibeast (or at least the version I'm using "Version 9.0.1 (1)") is automatically injecting Nvidia drivers regardless if you tell it to or not. You can check for this in the clover boot menu under "options" then view the graphics configuration. To fix this you need to mount the "EFI EFI" partition.
Open terminal and enter these commands:
diskutil list
Find the disk identifier for "EFI EFI"
mount /dev/disk***
Make sure you use the appropriate identifier for "EFI EFI"

In finder under "EFI" open EFI/CLOVER/config.plist with text edit.

Find these lines and make sure they set to false as in the images.
Save the file then reboot.

Once it boots all your monitors should work!
Thanks for your help guys!
