Docks & Hubs

USB-C identifies a connector shape, not one fixed set of functions. Check whether the laptop port supports data, video and power, and which protocol it uses. Do not buy a dock requiring Thunderbolt on the assumption that any USB-C port will suffice. The cable to the computer matters too: it can restrict functions or be permanently attached. Check usable length with the laptop in its usual stand or desk position.

Counting HDMI or DisplayPort sockets is not enough. Check resolution and refresh-rate combinations for one display and several displays, including operating-system requirements. An advertised arrangement may mirror screens rather than extend the desktop. Some products use video technology that needs additional drivers, potentially affecting protected content or managed work computers. Verify support for your actual model, not merely a broad computer family that may contain different hardware.

• Distinguish USB-C ports offering data only from ports that also provide video output.

Input power is not necessarily the power reaching the laptop: the dock reserves some for itself and connected peripherals. Check whether a suitable supply and cable are included. Several USB devices can share one upstream data connection. Copying files to a drive while other ports are active does not mean every socket has its full headline speed available. Check the Ethernet port's limit as well, especially for a fast local network.

A compact hub avoids carrying a large base, but short cables and closely spaced connectors can be awkward. A desktop dock needs room, ventilation and accessible placement for attaching accessories. Consider firmware updates and behaviour after waking from sleep. During the return period, test charging, displays and file transfers together. That reveals limitations missed by trying each port separately, and reflects how a fully connected desk will actually be used.
