locked Dell U2711 monitor

I received a Dell U2711 as part of a RMA. After hooking up the monitor and powering it on, I went to switch it to the input that was being used. Instead of getting the menu, I got a padlock icon appearing on the screen.

After doing some research, to unlock it you, hold down the button directly above the power button for about 15 seconds.  Unfortunately, it looks like you need to have a video signal on the current input.  Otherwise, the 'no signal' notification seems to interrupt the 15 second hold.   This also seems to interfere with other menu operations.
A nice feature for any future monitors would be to ignore the no signal  when the menus are up or if you really need a signal, try to auto-detect a signal and switch to that first.
