Mirrors fine but "Didn't detect another display"

[steveadams617]

DELL Monitor Stand with USB3.0 Dock
Model No. MKS14b

1) Plugged in and keyboard and mouse worked fine, but no video on the monitor

2) Went to:
https://www.dell.com/support/home/en...-mks14/drivers

3) Downloaded and ran:
DisplayLink-Dock-Driver_5DF5P_WIN_10.2.7042.0_A02.EXE

Mirrors the laptop screen fine but ""Didn't dected another display" when I click detect button in the display set up.

4) Rebooted computer, rebooted monitor stand/docking, tried another USB port without success.

Laptop information:

Dell Laptop Latitude 7490
Intel(R) Core(TM) i5-8350U CPU @ 1.70GHz 1.90 GHz
64-bit operating system, x64-based processor
Windows 10 ver 20H2

Dell Monitor Model number: P2414Hb

If I weren't getting any picture at all I would be tempted to update USB drivers, but don't want to mess around there if I don't have to.

Anyone have any ideas for me? Thanks in advance for your help.
