Laptop video ports (HDMI, DVI, VGA) are outies, not innies.
You can't use that for an input signal.
Would there be any other way for me to connect them? maybe through the network?
What about the webcam on the Laptop? would there be anyway for me to detect that as a device connected to the network, and use it?
Short answer: No
Long answer: Completely dismantle the laptop, figure out what power and video signal comes in over the ribbon cable, duplicate that from a video output from your PC and a power source, write your own drivers that will allow the PC to port the signal to the laptop video in that you modified before.....
Or just buy a new monitor at a yard sale.
