Review on ViewSonic VG1655 Portable Speakers: Frameless 1920X1080 Display with 🔊 Flicker-Free Technology, Blue Light Filter & Anti-Glare - Find out more! by Charles Lewis

Lightweight, doesn't add much to my luggage. Makes a great extra screen for my laptop when I travel for work. No battery works better for me because I can pack one in my checked baggage (lithium batteries are not allowed in checked baggage). The picture looks good as one would expect from an IPS monitor. An added bonus is that only a single USB-C connection is required to mirror my phone to this monitor. My phone (Samsung S9+) powers and sends video over a single cable, no external power required.
