Question Question about graphic card\chip and docking station

[rutledj]

I have a dell precision laptop with the INtel UHD Graphics 630 chip and a NVidia Quadro P1000. I'm connecting to a Dell D6000 Display port dock station via a usb-c connection.

I have 3 monitors connected to the dock station.

My question is, are the monitors being driven by some type of video chip in the dock station or are they still using the laptops built in processors? If the latter, is there a way to tell which monitor is being driven by the intel chip vs the Nvidia card?

My laptop becomes very sluggish (typing, mouse clicks delayed). The only thing I can see in task manager is the GPU maxing out.

gpu maxing out while doing what?
how the ram/ssd usage? how full is the ssd?
the laptop is should switch between nvidia or intel depend on the application

GPU maxes out when I notice the delay with my mouse and keyboard. CPU rarely maxes out. SSD is 1tb with 722gb free.
Ram 32g. It isn't more than 50% usage. Not sure where there is a place to switch between graphic chips. If you view the Performance tab in task manager, it shows both GPUs (GPU 0 Intel, GPU 1, Nvidia)
