This is a second screen you can carry with you. It's laptop-sized at 15.6 inches, weighs about as much as a thick book, and runs off USB-C power from your laptop — no wall plug needed. The OLED panel means the picture looks punchy with deep blacks, way better than the washed-out portable screens people usually settle for.
You get two USB-C ports, so you can plug in your laptop with one cable and keep charging through the other, or connect a phone. There's also a mini-HDMI if you're hooking up a camera or game console on the road. The 1080p resolution at this size is sharp enough for spreadsheets and video calls without squinting.
It's a 60Hz screen, so motion isn't silky, but that's fine for the kind of work you'd do on a portable. The real win is having an actual good-looking screen that fits in your bag.
