OK, so I tested it at home (1 external and 1 laptop screen), and it works fine.
Where it was acting up (consistently), was the same laptop plugged into the same dock model, but with 1 laptop screen and 3 external monitors. This was bugging out in both essentials and pro.
At work, 2 of the 3 externals are 1080 but the 3rd is 1440.
When I am back at work, as a test, I will force the built in Intel video card and then force the internal Nvidia, and see if they yield the same results. That would rule out video cards and video drivers.
