Does the CPU affect the display on the monitor?

CPU sets the frame + handles all AI/resource allocation, then passes the parameters to the GPU, which then draws the frame. At a lower resolution, the frames per second are limited to the speed of the CPU. At a lower resolution, the frames per second are limited to the speed of the CPU. So the CPU does its thing and sends the frame to the GPU.

Does having 2 monitors affect CPU performance?

Ultimately, anyone who uses multiple monitors should not worry about lost performance. Even on a single monitor configuration, running a video in the background will affect FPS.
