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:
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?
