Requirements

  • Original Dell D6000 power adapter and matching mains lead.
  • The documented charging options require the dock’s original computer cable.
  • Use the original host cable/USB-A converter and a USB 3.0-or-later host data connection; install current DisplayLink software.

Screen cables and full pair result

Windows; office use. Examples are not an exhaustive screen limit.

Use the specified power supply and original computer cable. Output ceilings do not guarantee charging speed or full-load power. USB peripheral, Ethernet, audio and power-button behaviour are outside this check.

Choose for the setup, not the higher number

If software installation is prohibited, the D6000’s DisplayLink requirement matters more than its headline screen count. If one-cable charging matters, check the laptop’s power requirement and the exact dock supply; a working USB-A screen connection cannot charge it.

WD19, WD19S and WD19TB are separate products. This comparison is for the original WD19 and D6000, not those variants or the D6000S.
