Didn't help, but read on for success.

you´re reaching the limit in your case.

Well, it reads to me that the max resolution of a monitor is 4096 (w)
x 2048 (h) -- so the 3860 is okay, but the 2160 is too high.

If I drop down the resolution to 2560x1440 then it works as expected,
but I didn't want to use this resolution and lose the 4K capability.

So... I followed this support link:

https://support.microsoft.com/en-us/help/2592687/remote-desktop-protocol
- -rdp-8-0-update-for-windows-7-and-windows-serve

I found that RDP 8.0 was already installed!  But I needed to enable it
using further instructions from the link....

With RDP 8.0 enabled, I get the desired full resolution of both screens!

Thanks for the heads up on the limitations from the link you provided.

Kind Regards
AndrewM
