Hi all
Recently bought a second hand Dell U2711. I wanted to clean it first so when I started cleaning the panel I pushed the buttons I some combination that of course I don't know and a black screen came up saying something about how long the screen was ON WORKING and things like that. I just wanted to know the order of button you need to press so that you can see check that again. I am thinking to buy a new Dell monitor and when I will sell this one I want to show that to the new potential buyer that the screen yes it is old but it was not working for a very long time. I found some combinations on the Google search for other dell screens but it did not work form me. Thanks in advance to anyone that can help with this.
