This is basically a second laptop screen that doesn't need its own power brick. It's 15.6 inches — the same size as a typical laptop screen — and powered through USB-C. Stick it in your bag and you've got dual monitors at a coffee shop or hotel room.
The picture is 1080p, which is standard laptop sharpness, nothing fancy but totally readable for documents and web browsing. It's not trying to be your main home monitor — it's trying to be the thing you actually carry with you. The stand folds into a cover, so setup is just prop it up and plug in one cable.
Good for side-by-side windows when traveling or adding a reference screen to a cramped desk. The 60Hz refresh means it won't keep up with fast gaming, but that's not what you'd use a portable screen for anyway.
