Anker Prime DL7400 A83B3

The Prime DL7400 combines DisplayLink screens with visible power and connection information on the dock itself. The useful question is whether that information and the charging arrangement solve a problem in your daily workspace.

Consider it for

  • A software-approved three-screen office desk
  • Users who want visible charging and connection status

Check before buying

  • 140W host charging has PD 3.1 and accessory-use conditions
  • HDMI does not support 5K or 6K; DisplayLink software required

Power figures share a budget

Up to 140W host charging requires a laptop supporting PD 3.1, and Anker says no more than one device should be connected to the front USB-C ports for that maximum. The dock’s 160W total output is not 140W for the laptop plus unrestricted maximum output on every accessory port.

Check the exact configuration and included power supply.

Treat the video connections as a supported combination

The manufacturer describes three external displays using two HDMI outputs and DisplayPort, with the highest resolution dependent on the selected connection and monitor. It recommends 4K60 for best HDMI results and states that HDMI does not support 5K or 6K on this dock. A high 8K headline is therefore not a shortcut to every intermediate display mode.

Software approval belongs in the buying checklist

DisplayLink installation is required for full multi-screen operation, including on Mac. The current supported Mac baseline is macOS 13.5. Its three accessory USB-C ports provide data and charging rather than additional monitor outputs. A useful pre-purchase exercise is to list the displays, power-hungry devices, and their expected simultaneous use; then check that arrangement instead of adding every port maximum together.

Anker 332 5-in-1 A8355

The Anker 332 is a straightforward way to add one HDMI screen, a few USB peripherals, and pass-through charging. It avoids the extra connectors of a large desktop dock, which is helpful when your actual setup is equally simple.

The Anker 553 brings two HDMI outputs into a small hub, but the two outputs solve different problems on Windows and macOS. A Windows setup can extend separate desktops when the host supports the required video path; a Mac repeats the same content on both external screens.

Compatibility

DisplayLink vs Thunderbolt or Native USB-C Docks

DisplayLink and Thunderbolt docks can put similar sockets on a desk while taking different routes to the screen. Thunderbolt and native USB-C video use display streams supplied by the computer. DisplayLink creates USB-driven virtual displays with compatible hardware and software. Choose the route from the exact host, monitor plan and application constraints—not from the HDMI count.

Dual Monitors on Mac: Chip Limits, MST & DisplayLink

To use two monitors with a Mac, first identify the exact Mac and chip, then decide whether the two screens will use native display streams, an MST path that may mirror, or DisplayLink virtual displays. Two sockets on a dock answer none of those questions by themselves. The steps below separate Apple’s display ceiling from the dock’s connection method.
