Which port is for what?

This is a functional port reference, not a drawing of the physical socket positions. Follow the labels on your unit. Anker 675 A8377: one HDMI output and dynamic charging

Before connecting

Up to 100 W dynamic host charging; confirm delivery with the accessories you use.

Use the intended powered-dock setup and host cable. Record each monitor’s input, resolution and refresh rate. Keep those requirements separate from the dock’s total port count.

Bring the desk up one screen at a time

1. Connect the specified power supply to the dock.
2. Connect the laptop using usb-c host connection for the laptop.
3. Attach one screen on a listed video path and select its wired input.
4. Confirm the operating system recognizes that screen before adding another supported screen.
5. Select the required modes and an extended desktop where supported. Check charging, reconnecting and your essential applications.

A useful check when something fails

If USB accessories work and HDMI does not, check the laptop’s USB-C video support and the monitor’s selected input. Data transfer alone does not demonstrate that the host connection carries a video signal.

Change one part of the arrangement at a time. Keep a note of the working monitor, cable and port so you can reproduce the result. If the remaining requirement has no documented answer, ask the manufacturer about the exact models instead of assuming the entire dock is defective.

Is it worth buying or replacing?

For two external screens, identify a separate supported laptop output or choose a different documented dock arrangement. Do not count a USB accessory socket as the missing second video port.

Use the setup checklist to compare complete arrangements, including any adapters and separate charger. The evidence here is documentation-based; Connect Your Dock has not physically tested this desk.
