U3023E, sleep mode caused by USB-C when using DP
Hi,
I connected two devices to the U3023E:
USB-C work laptop with charging
Computer with DP and USB-A
KVM for U3023E and keyboard
When working on a DP computer, the work laptop goes to sleep from time to time (or I manually put it to sleep). This causes the U3023E to go blank (probably sleep mode) even though I use it on DP all the time. To be able to use it on DP, I have to turn on the work laptop connected via USB-C.
No Events found!

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.
