RE: U2711 OSD Locked Out

Holding the menu button for 15 seconds WILL work - but there is a caveat!

In order for this to work, you must have a cable connected to the selected source with video input. For example, on my monitor, the selected source was VGA and I could not switch it to DVI. So I connected my U2711 to the VGA port on my laptop, switched the laptop on, and then held the menu button on the monitor for 15 seconds. Bam. Unlocked right away. I had tried unlocking all night without any luck. Only when I plugged in a VGA cable to the monitor with input was I able to unlock it.

It took me so long to figure this out that I took the time to create an account with Dell to share my findings. Best of luck unlocking your monitors!

I have a U2711B and the lock button started appearing for some unknown reason.  For me, holding 4+5 did not work, but then I just tried holding button 5 (the bottom button) for about 15 seconds and the display unlocked.

Just had one of these come in to our shop today. After trying all of the other suggestions, this one worked.
 
 
 
 

I had this problem with a Dell U2711 screen.

None of the above techniques worked. But then I stumbled upon a solution.

Solution

  1. Turn on a computer that is plugged into the currently selected screen input port (might require trial and error to work out which one).
  2. Press and hold lowest capacitive button for 15+ seconds.
  3. Screen stays on for the 15+ seconds required to unlock. Win.
