How to Unlock Dell Monitor_

If you are using a Dell Monitor and want a quick guide on locking and unlocking the computer screen, then you are at the right place. I will show you the easy steps to unlock the Dell display without many efforts.

Sometimes, users get a lock symbol at the centre of their screens. This icon doesn’t stay for a longer time and it appears & disappears frequently. As the Dell monitor has a number of functions and menus which help to change the basic and default settings of the screen like brightness, color, vertical & horizontal position, resolution, etc. But, if you accidentally or intentionally press the wrong button, then the Dell screen can be locked as it has such kind of technology from the company. So, you should know the exact key combination to unlock the Dell display.

Let’s have a look at some useful solutions for that.

How to Unlock Dell Monitor?

Solution-1: Press & Hold Menu Button

One of my friends has a Dell U2412 monitor. This locking problem happened to him when he was setting up his screen for the first time. By chance, I was present at the place. After some unsuccessful handful tactics, I tried to press the menu button for some moments, 15-16 seconds to be precise.

So, as a quick solution to unlock the monitor, just press and hold the menu or settings button for 15-20 seconds. The screen should open now. If you have an advanced Dell monitor on which the above method doesn’t work, try to press and hold the bottom button (not the power button) for the same duration mentioned earlier.

Solution-2: Make a Cold Reset

This technique works in most the cases. So you can also try it. Making a cold reset means, turning down all the power and removing the connected cables and then again starting a fresh. Follow the steps below:

  • Disconnect all the cables including DVI, VGA, USB, HDMI, power, etc.
  • You can take the help of screwdrivers if the connectors are not opening by hand.
  • After you finish the above steps, press & hold the power button for 5-10 seconds. This will discharge all the remaining power from the monitor.
  • Now, release the button and press it again to turn off the monitor.
  • Wait for a few moments. Then, connect all the cables again carefully and start the screen.
  • Follow the procedure in solution-1 and the problem will be solved.Make a Cold Reset

    Hi. I blocked the Dell U2412M monitor.
    There is no need to disconnect anything, not even the cables from the monitor.
    Let the monitor run, and then all you have to do is hold the button firmly over the Power button for 20 seconds (the buttons on this monitor are not described except for the Power button icon).
    Then the open lock icon will appear on the monitor, and you’re done.
