What should you check before buying?
Confirm two-screen extension on your exact laptop and operating system first; then check for a webcam data port and, if needed, laptop charging. A native USB-C video hub and a DisplayLink dock take different approaches, so the connection type matters as much as the sockets you can see.

What to check |
Who this matters to |
| Two independent displays |
Check the laptop’s external-display limit and the hub’s stated extended-display support for your operating system, including the intended resolution and refresh rate. |
I need separate workspaces for a call and other tasks, not the same picture on both screens. Around 42% of consumers put independent display output first. |
| Mac or USB-A compatibility |
Identify the exact laptop model and whether the dock uses native video output or DisplayLink; check the latter’s software requirements. |
When I switch laptops or use a Mac with a limited native display count, a connection that works with my computer matters more than an advertised HDMI count. Roughly 33% of consumers prioritise this compatibility. |
| Webcam and peripheral ports |
Count downstream USB data ports that match your devices; do not count a charging-only USB-C input as a webcam connection. |
I want to leave my webcam connected without repeatedly unplugging the other devices I use at my desk. About 17% of consumers make data-port availability their primary concern. |
| Charging at a fixed desk |
Compare the laptop’s charging requirement with the dock’s stated Power Delivery output, and check whether a suitable charger and cable are included. |
If the dock can also charge my compatible laptop, I can avoid a separate laptop charging connection. For around 8% of consumers, charging and desk expansion come first. |

Frequently asked questions
Will two HDMI sockets give me two separate external screens?
Not necessarily: the hub and your laptop must support two extended displays together. Microsoft Support notes that a splitter duplicates one signal rather than creating two independent outputs, so check the stated display mode for your operating system.
Can I use a compact dual-HDMI hub with a Mac?
Yes, but whether it provides two separate external desktops depends on the Mac and the hub. Apple Support says native display limits vary by model and display settings, while Anker UK says its A210B mirrors its external displays on macOS. If you need two different desktops, check a compatible DisplayLink dock and its setup requirements.
What does a DisplayLink dock need on macOS?
It needs DisplayLink Manager and the Screen Recording permission required by that software, according to DisplayLink Support. Check that your chosen dock uses DisplayLink and that its stated display modes meet your needs; DisplayLink Support also warns that some protected video may not play while DisplayLink screens are connected.
Can the webcam use a USB-C Power Delivery socket?
Only if that socket is explicitly data-capable. On Anker UK’s A210B, the USB-C Power Delivery input is for charging, while separate USB-C and USB-A ports carry data; connect the webcam to a suitable downstream data port.
Can one dock connection also charge my laptop?
It can if the laptop accepts USB-C charging and the dock’s output meets its charging needs. Compare the laptop requirement, dock pass-through rating and required charger: Anker UK states up to 85W laptop output for the A210B, while Targus UK states up to 80W pass-through for the DOCK116GLZ. Check whether the charger and cable are included with the model you choose.
