It sounded like, on your video with the ethernet grounding kit, you said that it is even more important to ground shielded ethernet cords because they conduct electricity better than unshielded ones. That is interesting.

But if the monitor grounds the laptop, would the laptop ground the ethernet cord?

The switch is all plastic, a Netgear GS908. It sits quite far from me- 8 feet away? and is hooked into the wall ethernet, not the router.  A phone is near me that is hooked up to it.  

The laptop-I'm not sure what it's made of. It could be light metal or it could be metal-colored plastic. It is a Dell E-7440.  The ethernet cord is just a hole in the side- I don't see any tabs or beads. It sits 2 feet away from me, but my keyboard and monitor are hooked up to it.
