Thats actually a good thought. In the Dell 5520 firmware you have the option to
set discreet graphics and use the nvidia card for display rather than intel. In
the Dell 5570 I think this architecture has changed somewhat, but I don't
understand it. Curious if Nvidia knows. I can make a post to their forum and
see if anyone has any understanding here. In asking them before it seemed to me
that they at least understood the architecture and the way it was supposed to
work.
