The LG monitor has a 5K resolution, a wide range of color, four USB-C ports, and at least one built-in camera (and possibly more). It can connect to your MacBook using a single cable and, since it's USB-C, that same cable can also be used to charge it.
According to Apple exec Phil Schiller, Apple worked with LG to create a display that's the ultimate docking solution for your new MacBook Pro.
The 5K monitor can display 35 million pixels, driven by the graphics circuitry of the new 15-inch MacBook Pro, which can run two of the displays at the same time. Full specs, pricing and availability have yet to be announced. Considering both the new MacBooks and 5K monitors cost more than a few pretty pennies, we don't expect the self-described "ultrafine" LG to come cheap.
