Think portable PC monitor and something pretty puny probably comes to mind. What you're probably not imaging is folding contraption with dual 24-inch 1080p displays. What you probably didn't think of is the extraordinary Acer PD243Y E Portable Monitor.
It's immediately obvious that the term "portable" is being used pretty liberally by this unusual dual-screen monitor. You're not going to be slipping it into a small bag with your 13-inch thin-and-light laptop.
