TLDR: The Uperfect 15.6″ Portable Monitor is an on-the-go second screen that brings HD-quality video when connected to a smartphone, laptop and more. Second screens always come in handy, especially when the first screen is a little on the small side. You can practically feel your eyeballs scrunching up and your vision deteriorating as you hold a phone screen inches from your face while you play a game or try to get some work done on that minuscule canvas.
