This is Dell's Power Button Sync feature that renders monitors supporting it useless in two computer setups. You cannot disable it. Yes, it's brain numbingly stupid. It's sad that a company with Dell's resources and reputation can drop such a clanger.
There is no solution and Dell doesn't care. I was lucky, I was able to reverse to earlier firmware without DPBS on my U4021QW.
Search for DPBS to see all the threads discussing it.
