I have a Dell Inspiron 7520 and a Dell D3000 docking station connected through the USB 3.0 port. Before updating to Windows 10 (I was using Windows 7), everything worked fine. Two monitors were connected to the docking station (one through the HDMI and one through the DVI port) and my laptop used all three displays just fine.

After updating to Windows 10, no monitors that are connected through the docking station are detected. The monitors are detected if I plug them directly into the laptop's HDMI or VGA ports. However, other USB devices (e.g. keyboard, mouse) still function properly through the docking station. Only the display monitors seem not to be detected.

I upgraded the driver for the D3000 to the most recent one (here). But this did not help.

First you can check your device manager if you have any display adapter drivers that have stopped working. If you have an Intel driver that has stopped due to a problem there may be a work around.

We found that if you opened the laptop lid and then restarted the computer, the external monitors would identify and work. You could then close the laptop screen and continue working but whenever the laptop is turned off or undocked it would need to have the screen open in order to identify the monitors.

This is by no means a long term solution but it seems like this is a problem with Win 10 and will hopefully be fixed in the near future. I haven't tested it yet but I also so that Nvidia pulled their driver from last week due to some display issues so maybe that was the problem.

This may be useful to some. My computer is a Lenovo W530 and with the same issue, after I reinstalled Windows 10, the monitors connected to the DVI ports on the dock, did not work. This computer has a second video card Nvidia Quadro and I went to Windows system directory and found an application which is the control panel for the Nvidia. There all I had to do was to enable the monitors on DVI ports and it all worked. Perhaps on Dell the solution is similar. For some reason, Windows 10 installation does not add a shortcut for the Nvidia control panel as it does for the Intel Graphics that only controls the laptop screen, so I had to hunt for it.

Just incase anyone else is having the same problem I had:

  • Check that the power to your docking station is plugged in correctly.

I have a laptop connected to two dell monitors via usb to docking station. What worked for me was disconnecting the USB that connects to the docking station, closing the lid, waiting a few seconds and then plugging the usb back in.

Yesterday I updated my NVIDIA driver through "NVIDIA GeForce Experience" and it worked.

Today it doesn't work. I tried disabling and enabling both Intel onboard and NVIDIA video cards' drivers, restarting, reinstalling drivers but it didn't help.

Then I found this link that was saying that the sequence of reattaching cables is important. I tried it. It didn't work.

Then I tried to replug USB 3.1 cable, so the side that was in docking station I put into laptop and the other end that was in laptop into docking station, and it worked.

I am still not sure which of those made it work, but it feels like the reattaching the cables worked for me.

What worked for me was:

  • open Device Manager
  • under "Display Adapters" select and disable the NVIDIA graphics card
  • wait a few seconds
  • re-enable it

My Lenovo P50 has an Intel and nVidia gfx card, so if I disable nVidia, the laptop screen continues to work (by the Intel gfx). If you only have one graphics card, the after disabling it you might stay with no active display at all, so you can not re-enable it. Maybe a script would help...
