Dell dock: monitors non-responsive after sleep

I am setting up a new office with two HP 27xw monitors connected to a Dell e-dock. Everything is working quite nicely, except after going to sleep, the monitors are no longer visible to Windows.

So far, the workaround is to press the physical undock button (releasing the laptop) and then re-dock the system. All while keeping the laptop’s lid/display closed.

Also, to prevent this from happening I have set Windows 10 to never put displays to sleep when the system is on AC. Of course the downside is that I have to physically switch off my monitors if I want to save power.

I plan to investigate the problem further, but for now this is where it stands 😉
