@aurynn@cloudisland.nz OK, I'm no expert here but, from what I understand...
Systems may have a mux, which allows routing of graphics signals between cards and ports. In that case you have options.
Lighter more portable laptops are likely muxless. In this particular setup with integrated Intel graphics, and an NVidia Optimus discrete card, it is probably wired so that the discrete card passes its signals though the integrated card to display things. So when you disable the integrated you lose access to the extra ports. This is cheap, light, and efficient.
Windows will choose for you which card to use for which task, and it uses the integrated graphics for basically everything unless something like a game engine specifically asks otherwise. This saves lots of power since it doesn't need to run the discrete card.
Again, great for going to meetings and taking notes, but my burning need is to compile so so many tiny JS packages.

@aurynn@cloudisland.nz I haven't done numbers, but running two 4K monitors definitely feels like it hurts the laptop's performance in big way.
