I kinda like the look of them and often feel myself wanting a second monitor if I’m working on my laptop.
(I’ve come to the conclusion if people think I’m working I won’t look like as much of a massive dork)
Always had the feeling they’d be a bit crap though, like the hinges break or the monitor isn’t too good or it’s big and bulky and you can’t really carry it
Ideally I’d like to find a single fold out side monitor that attaches to my laptop (big chunky ThinkPad) somehow and doesn’t need its own power supply but that may be asking too much
I got a NexiGo portable gaming monitor that I’m pretty happy with. It is a 16 inch 2560x1600 display, 144Hz, and supports FreeSync. I got a bidirectional DisplayPort to USB C cable so that I could use it with my desktop for LAN parties and it’s great. It has a built in flip-out kickstand, a folding magnetic cover, OK built in speakers (good enough to game with anyways), and can be powered via a second USB C port with an A to C cable. On a device that supports USB C video output like a laptop or Steam Deck it can run off a single cable but I mostly wanted it for my desktop.
