I use this monitor with a MacBook Air and docking station. It worked well yesterday. Today, I can't get it to work. It used to "beep" when I docked my MacBook. Now nothing. I've checked all connections, but I get a message "No DP Cable". The cable is in snug and in place, so there is a DP cable.
I've tried unplugging the monitor - No success
Remove and reattach DP cable, all connection secure.
I'm thinking the DP cable went bad all of a sudden. I've had the monitor for less than a month.
