1.12 complete mess > was fine on 1.10

[junky]

dang - found what might be a solution but time will tell

- updated back to 1.12 - still same issue
- unplugged each display link cable from dock and plugged back in - 1 at a time - immediately the displays connected at full resolution and appear fine
- shutdown and restarted and all working

what the heck - noted I had power cycled the dock a few times during this mess - and power cycled the monitors. Seems something of the monitors needed to be re-detected after the update. Strangest part is that 1.12 did work fine on 15.3.2 for me for 1 day - then it broke 2nd day.
