i just got the monitor and things were going well with HMDI (1) to miniport cable but then I wanted to compare this to a HMDI (2) to HMDI cable. Somehow that didn't go well and although it now works with the initial configuration I cannot get the monitor to unlock so I can access controls. When I push the button I get a symbol of a lock in the middle of the screen. Would like to be able to access controls. Any ideas? They would be much appreciated. Love the monitor but don't like this kink.
I have tried unplugging both monitor and computer, restarting computer, etc. but nothing so far.
Many thanks!
