I love this LCD. It is large enough and I can connect my computer via USB-C. Everything is connected to the monitor so my desk is relatively clean of cables. But then one day I updated the firmware and installed Dell Monitor Manager.
After a while, I realized that if the monitor goes to sleep mode, I can no longer connect it to it. The only way was to physically remove the electricity cable and start LCD again.
One month later I decided to contact support. The next day I had a call and we talked about the options. I updated the firmware and updated the drivers. It did not help.
In the end, I removed Dell Monitor Manager and realized that it was caused by it! Now my monitor is great again and I don't have to restart it again and again.
Lessons learned: If something is working, don't touch it!
