KVM Switch or Docking Station: Which Problem Are You Solving?
Docking stations and KVM switches both sit between computers and desk accessories, which is why they get confused. They solve different problems, and a few devices try to combine both roles.

A dock expands one computer
An ordinary docking station connects one host to more ports: monitors, Ethernet, USB devices, and often charging. If only one computer ever sits at your desk, a dock is usually the simpler choice.
A KVM switch shares a desk between computers
A KVM switch lets two or more computers take turns using the same keyboard, mouse, and monitors. If you move between a work laptop and a personal desktop, this is the role you need.
Combined devices: read the model, not the category
Some products are sold as a KVM switch and docking station in one. The AV Access iDock C20 is an example: its documentation describes dual independent displays through MST, while macOS receives duplicated displays over its USB-C connection. That applies to this model only. Other combined devices may behave differently, so read the exact model's documentation.
Questions to settle first
How many computers will connect? Does each need charging? How many monitors, at what resolution and refresh rate? Does each computer's port actually support video?
Your pre-purchase checklist
- Count the computers that will share the desk.
- List each computer's model and its video-capable ports.
- List monitor models with the target resolution and refresh rate.
- Decide whether you need charging, Ethernet, or extra USB ports.
- For combined devices, check per-OS display behavior in the manual.
- Confirm with the seller before ordering.
