T570 monitors turning off on ultra dock

I have T570 and two same "thinkpad ultra dock" docking stations - one at the office and the other at home- with two monitors connected on each of them (DP & HDMI). At the office, I close the lid (2 screens) and at home I keep it opened (3-screen setup).

 

A while ago it started flickering / blanking external monitors on *both* of them. Sometimes, when computer is left locked for some time (sleep is disabled!) external monitors are blanked and I can only revive them by removing + attaching the laptop to the dock again.

 

I tried firmware updates on dock, driver updates on windows / lenovo... nothing helps. Windows 10, latest updates.

 

I find it weird that two docks would go bad almost simultaneously. What else can I try - it is driving me crazy as I cannot work normally (sometimes it blinks like every minute or so but other times it is OK for more than an hour)?

And we're back...

Move delayed but still coming
