This is the monitor you throw in a backpack when you're working away from your desk. It's laptop-sized at 13 inches, powered by a single USB-C cable so you don't need to hunt for outlets, and the OLED screen means blacks look properly black instead of that grayish glow regular portable monitors give you.
The picture is sharp enough for normal work — reading documents, browsing, watching videos — but at 1080p on a small screen, don't expect the razor-sharp text of a 4K monitor. It refreshes 60 times per second, which is fine for everything except competitive gaming. The HDR label is there but on a screen this small and portable, treat it as a bonus rather than the main event.
It's genuinely portable. Two USB-C ports mean you can charge your laptop through the monitor while using it, or just power the screen directly. There's a mini-HDMI if you want to plug in a camera or older device.
