I haven't been able to set up a multiple monitor display with my laptop.

I have the following setup:

HP ENVY 17-cg008ca FHD Laptop
comes with Nividia GeForce MX330 and also Intel Iris Plus Graphics
the monitors are running off the Intel Iris Plus Graphics

I have the laptop running through an HP Thunderbolt Dock 120W G2, that has two (2) DVI ports in the back.
I have two (2) Samsung S27D850 monitors attached to the Dock by DVI cables.

All monitors have been tested and swapped individually.
All cables have been tested and swapped individually.

Here's what happens.
The monitors are recognized by the Intel Iris Plus Graphics Card.

So the monitors are running off the Intel, and I can get any combination of one monitor and/or the laptop screen, however the 2nd monitor continually is in "Disconnect this display" option mode. Even when I attempt to change the option for the 2nd monitor, it will not change.
I've ran the options so that the laptop screen is on Disconnect, so I'm running solely off one Samsung monitor, but when I try to extend the display to the 2nd monitor (#3 in the pics), the 2nd monitor still stays on "Disconnect the Display".
If I unplug the monitor that is working from the Dock, the 2nd monitor will actually start up, and the Intel will start up what was the 2nd monitor, now as the 1st monitor.

The Intel can see both monitors, but I just cannot get the 2nd monitor off of "Disconnect this display" menu option.

I've tried both the Windows 10 Display Settings, Intel Iris Graphics Control Panel, Intel Graphics Command Centre (which does not have a multiple display option, even though it sees all 3 screens), and also the Nividia Control Panel to try to get the desktop to either extend, clone, and just be Active, but all permutations and combinations did not change alter the setting "Disconnect this display" on the 2nd monitor (#3 in the pics, which is constantly greyed out).

If anyone has any experience with this I could really use some help.

Thanks!
