Trouble getting laptop built in monitor to work. Ubuntu - Nvidia

I'm having issues getting my laptop monitor to display when using the nvidia-driver-525.

I've tried removing the /etc/X11/xorg.conf file and rebooting, which enables the use of all 3 screens again, but then running nvidia-smi shows low GPU usage, making me think it's not using the nvidia drivers and it's using the intel chipset graphics instead. It also lags badly when moving windows around, as if it's not using the nvidia driver, so I think it defaults to the intel graphics instead?

My setup is as follows:

• MSI GP63 Leopard 8RF
• Intel® Core™ i7-8750H CPU @ 2.20GHz × 12
• NVIDIA Corporation GP104M [GeForce GTX 1070 Mobile] / NVIDIA GeForce GTX 1070/PCIe/SSE2
• 2 external monitors, one using the Display Port output and the other using HDMI

here is my xrandr:

I'm pretty sure DP-1 is my laptop's built-in display.

Here is my nvidia-smi while x server is using the xorg.conf file:

I'm at a total loss here. I've been playing with this all day and am about to give up. Not sure what else to try here. I could use some help/suggestions.
