ASUS MB169B+ will do the job for a portable monitor. It's very light, 15.6" IPS 1080p pulls power and display over USB3 (there's also a C model)
But then you've got to add a keyboard and a mouse and probably the biggest problem, you've got to figure some way of getting the monitor to an ergonomic height.
