Windows 10: Extermal monitors are disabled after logging in - Surface Pro 4 & Dock

Hi all, recently I've been plagued with a very strange issue regarding my external monitors that I cannot seem to resolve. I have the Surface Pro 4, with the surface dock, and two external monitors. The issues coincide with upgrades to the monitors, going from 1080p Asus monitors, to 2560x1440 AOC (Q2577PWQ) monitors.

Problem:
After waking the surface from sleep, a reboot, or cold boot, monitors are not functioning at all. I keep my surface closed when docked, so this requires opening it up, and doing troubleshooting from the surface. On looking in Display Settings, the external monitors are set as disabled!

2nd Problem:
In addition to the above, I have mixed success in getting the external monitors to function properly again. I can sometimes enable 1 monitor, but then trying to enable the second one results in an error message directly above the "Multiple Displays" heading in Display Settings: "The display settings could not be saved. Please try a different combination of display settings."


I'm starting to think perhaps there is a strange issue with these monitors and surfaces? I have tried a different docking station, as well as a different Surface and encounter the same issues. I have also tried installing the latest Intel HD 520 driver from Intel, which also has no luck. I really like these when they work but it seems that the problem is getting worse and It's hard getting even one screen to function normally now...

Surface Pro 4 Docking issues

I have a Surface Pro 3 and a Surface Pro 4, two docking stations, two external monitors, keyboards and bluetooth mice.

Up until two weeks ago, everything worked great. (since December)

Then, (after an update) the Surface Pro 4 monitor does not go full screen. There is a wide black border and it has to be extended each time.

I put the Surface Pro 4 on the Pro 3 dock and same thing. (Yes, they are the identical dock, monitor and keyboard)

Surface Pro 3 works great on both docks so it is not the docks, monitors or cables.

This is getting frustrating.
