Monitors on and black screen after installing Nvidia drivers

Hey guys I've been trying for the last two days to get my hack to work with the Nvidia drivers. It will install Sierra just fine and I've been able to update clover and install other drivers using multibeast. The first time I tried this, I installed the Nvidia drivers through multibeast, rebooted, and everything was fine until I opened my display preferences. Then both my monitors went black except for the cursor. Booting with nv_disable=1 didn't work, neither did safe mode. Even though it said the drivers were disabled in the log, it still booted to a black screen. I've re-installed Sierra 4 times now, trying different drivers/fixes each time, and nothing is working. I've tried installing the drivers from Nvidia's site instead of using multibeast's package and tried using both the regular Nvidia driver injection and the web drivers. The drivers are enabled in clover's plist, and using nvda_drv=1 doesn't change anything. I've tried using the MacPro(can't remember the version), iMac14,2, and iMac17,2(With lilu.kext and NvidiaGraphicsFixup.kext). I am completely stumped. I've spent hours looking at guides and trying different things, and I'm hoping someone here will be able to help me.

Thanks, Gabe
