.... The first screen I received was far too bright - even after adjustments - and had a really too dark area in the upper left corner. A call for service DELL, and they showed themselves more than equal: the next morning, I had a new screen in front of my house, not even time to pack the old! "Okay," said the driver, "I will return tomorrow to take" what he did: The second screen is very correct, and the DELL service is quite extraordinary efficiency!
