For Sierra, nvda_drv is a separate nvram parameter which is set by the NVIDIA Driver Manager preferences panel when you select the NVIDIA Web Driver:
Code:
sudo nvram boot-args="nv_spanmodepolicy=1"
sudo nvram nvda_drv=1
Once you boot into macOS, you may need to turn off the display for 3 seconds, then turn it on for 5K to be initialized.
Hi, I can get this to work in 5K (Nvidia 1070 on Dell UP2715K) if I use clover boot args as nv_spanmodepolicy=1 nvda_drv=1 and cycle the monitor power - but it only works for that boot. I've tried adding the terminal code above, but I get an error saying "nvram: Error setting variable - 'boot-args': (iokit/common) general error". I found some help that suggested I needed to do the changes in Recovery mode, which did allow me to set the arguments, but they didn't stick for the next boot. How can I add these arguments to the boot permanently please?

Actually I've figured it out. Sorry I'm quite new to all this. I downloaded Clover Configurator and in the Boot section, it has both those arguments as tick boxes. Added them to the config.plist and it work after a reboot.

I haven't seen the mouse cursor problem (NVidia + MST display) since before High Sierra 17A405 and 378.10.10.10.15.117. I'm using High Sierra 17A405 and 378.10.10.10.15.120 now.

If you use this monitor, use Lilu.kext and NvidiaGraphicsFixup.kext, adding "ngfxpatch=pikera" as a boot arg will fix every workaround for this monitor.

You will not need to powercycle, you will not have the mouse pointer bug, so basically everything will work.
