Belkin 11-in-1 Multiport Dock INC004

The Belkin INC004 is useful to examine when the desk still includes a VGA display or projector. It combines VGA, HDMI, and DisplayPort in a wedge-shaped dock that can also sit beneath a laptop.

Check before buying

Not a triple-4K extended-display solution
Official page excludes 2020 M1 MacBooks; macOS mirrors external outputs

The VGA socket changes the display math

The official matrix lists a single HDMI or DisplayPort screen at 4K30 and a single VGA screen at 1080p60. Windows dual-extended mode is listed at 1080p60, while triple extended mode drops further. This is therefore more of a legacy-connection solution than a modern triple-4K workstation.

Check the exact configuration and included power supply.

Power input and laptop output are different numbers

Although marketed with a 100W pass-through input, Belkin reserves 15W for operation. A suitable 100W supply therefore leaves up to 85W for the host, and the charger is not included. If you reuse a 65W charger, the available laptop power is lower again.

Read the explicit Mac exclusions

The detailed page limits macOS to mirrored external screens and states that 2020 M1 MacBooks are not compatible. Those notes take priority over a broad Mac-and-PC description. Its short attached cable and rear-facing sockets also need to fit the physical setup. Measure where the laptop’s USB-C port sits when raised on the dock, especially if several stiff monitor cables will be routed behind it.

Belkin 11-in-1 Pro GaN Dock INC020

The INC020 places its power supply inside the dock, reducing the need to hide a separate brick behind the desk. That is a practical layout benefit, but the display arrangement deserves attention before the cleaner cabling becomes the deciding factor.

Does Your USB-C Port Support Video? Check This Before Buying a Dock

A charging light, a working mouse and a blank monitor can all occur in the same docking setup. They test different functions. Before replacing the dock, establish whether the selected laptop port supplies native video and whether the cable and dock preserve that route.

Docking Station Charging: Read the Wattage That Reaches Your Laptop

A dock marked 100W does not necessarily deliver 100W to your laptop. That number may describe its power input, its host output or another port entirely. The charging decision becomes clearer when you follow the power from the wall to the computer and attach each wattage to the right connection.
