I just bought a Dell U3214Q. It´s been working great for 5 minutes. Then I disconnected my MacBook, reconnected it again after a while, then the computer just froze straight off, the monitor showed a message of not getting signal from the MacBook and going to power save mode.
At a second try the MacBook just went black and the monitor showed the same error message.
Several reconnects, restarts, booting in save mode and disconnecting the power cable didn't change a thing.
Anyone ever had this sort of issue before or knows any troubleshoots?
I´m using this MacBook click, a Mini DP to DP cable that I tested with another monitor.
Thanks for your help and best regards from Germany,
