I've tried this solution. There's a chance I've done it wrong though.

cat /etc/modprobe.d/nvidia-power-management.conf
options nvidia NVreg_TemporaryFilePath=/run
options nvidia NVreg_PreserveVideoMemoryAllocations=1

AND:

cat /etc/default/grub | grep "CMD"
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nvidia.NVreg_EnableS0ixPowerManagement=1"
GRUB_CMDLINE_LINUX=""

Upon systemctl suspend the monitor loses connection then gets its back after about 30 seconds and shows the login screen.
