Desktop isn't a requirement though. I have 38" LG and connect the work laptop to it with just one USB-C cable. That handles power, monitor, mouse, keyboard, webcam, and audio. It's great.
Agreed. I meant more in the sense of a stable and full-blown workstation with a proper screen, keyboard etc. Of course you can also do it with a laptop, if you wanted to (minus being able to upgrade the hardware as much).
True. I have a laptop from work dedicated to work only, so I do have a desktop too for private use. This work out very well with this setup as I only need to switch that single USB-C cable and my monitor + all peripherals are changed from the laptop to my desktop.
