I've lately bought a WD19 dock to extend my HP Windows 10 laptop display to two Dell monitors.

Both monitors work when plugged directly into the laptop's single HDMI port one at a time.

The dock doesn't seem faulty, it has power, connects the keyboard and mouse through USB and I've tried a replacement.

However, neither monitor will work through the dock, whether connected by HDMI or DisplayPort (I bought an adaptor after seeing the other posts recommending it was the way to get dual monitors working).

I've updated the laptop BIOS and tried re-installing the Realtek drivers and firmware update, but still can't get the laptop to detect the monitors via the dock.

Error message when connecting says 'the USB device malfunctioned and windows does not recognise it'.

I'm about ready to return the dock unless anyone has bright ideas?

 

Thanks.
