Unable to duplicate or change Display settings on 2nd monitor

[Bryce Curdy]

Apologies for duplicate post but the forum is now allowing me to attach zipped Support File.

ASUS Laptop connected via Targus Docking Station (USB) to LG Monitor (HDMI)
Intel HD Graphics 4000 Display Adapter (latest driver)
NVIDIA GeForce GT 650 M (latest driver)
Windows 10 64 bit (1607)
DisplayLink 8.1 (Compatibility Test passed)

I cannot remember the last time I tried to duplicate display as it's not something I need to do very often plus I've just moved home and had no study for several months but it was something I was definitely able to do when I first installed DisplayLink. At that time I was using Windows 7 since when I have upgraded to 8 and now 10. I've read on other posts that Intel 4 series have limitations but I could definitely duplicate on Windows 7 and pretty sure 8 too.

Windows Button and P pressed together gives me the option to duplicate but it doesn't work. No option to duplicate using Display settings and unable to change any settings on the monitor at all. Resolution looks like 1920x1080 but the resolution box is greyed out under Advanded display settings. Under NVIDEA settings I get a message that I am 'not using a display attached to an NVIDIA GPU'.

If I bypass the Docking Station (ie Laptop to Monitor via HDMI) Display Settings behaves as described above but I can now change resolution and other settings using NVIDEA settings.

Extremely grateful for any advice.
