Dockingstation for cp2640ng

[User53117]

Hi Community. I have purchased a HP Laptop cp2640ng and tried to connect to a dockingstation for use of 2 additional monitors, external keyboard and mouse (tried HP G5). This does not work (no connection to screens). Does anyone know how to fix it OR is my laptop compatiblöe with a dockingstation and if yes: which one? Thanks for your help. Peter

Hi @User53117,

Welcome to the HP Support Community!

Thanks for reaching out!

We're thrilled to have the opportunity to assist you and provide a solution.

Sorry for the inconvenience caused don’t worry let me help you.

To better understand the issue, could you please provide a few more details?

• When you connect the HP G5 dock, do the external keyboard and mouse work, or is it only the displays that fail?
• Are you using HDMI/DisplayPort cables directly from the dock to the monitors, and have you tested those cables separately?
• Does Windows detect the monitors at all in Display Settings, or are they completely absent?

 Troubleshooting Steps You Can Try

• Check USB‑C Port Type: On many HP Pavilion/17 series laptops, the USB‑C port supports data and charging but not video output. If your model doesn’t support DisplayPort over USB‑C, the dock won’t be able to drive external monitors.
• Update Dock Firmware: HP provides firmware updates for the G5 dock. Install the latest version from HP’s support site to ensure compatibility.
• Update Graphics Drivers: Make sure your AMD/NVIDIA/Intel graphics drivers are up to date. Outdated drivers can prevent external displays from being recognized.
• Test Direct Connection: Connect one monitor directly to the laptop’s HDMI port (if available). If that works, the issue is likely dock compatibility rather than the monitors themselves.

Since the G5 dock is designed primarily for business laptops with full USB‑C/Thunderbolt video support, your model may not be fully compatible.

I hope this helps.
