I disagree with the more than 4K being a theoretical need thing but, regardless, where I work, every desk has a pair of 4K monitors that connect to the user’s laptop via a single USB-C cable. That cable also connects a keyboard, mouse, gigabit ethernet and, depending on the desk, 10Gb ethernet, multiple cameras and conference audio. The cable also charges the laptop, of course. At the moment that’s mostly done using USB-C docking stations, but we’ve started to deploy monitors that are USB-C native and can be daisychained together.
