I just purchases a dell 34" u3415w monitor which arrived yesterday to use as an external monitor with a macbook pro 2010. Well, it doesn't work in any way/shape/form with the laptop. The issue is with the MACBOOK I'm sure, because the mac slows to a grinding halt when I connect the monitor and it doesn't output any video signal. I've been testing different solutions from forums, one of them is to change the OSD settings on the monitor, to change the DP 1.2 protocol. Which brings me to my current question here on the Dell forum:
When I touch any of the four "buttons" on the front of the monitor, every one only gives me the "input selection" quick menu. I can't seem to access the main menu or any other settings on the monitor.
I've tried with the monitor not connected to any computer, powered on and off, disconnected power source... yet all four touch buttons only show the input select menu. Is this normal behavior for the monitor?
