Today my new Dell came(not from Dell). I have not tested it.
If it uniformity compensation on, the brightness at 100%. This is too bright.
Does anyone know how to get into the sevice menu? Maybe you can change what there.
On my first u3415w the display was yellow on the left, too. The active color uniformity compensation corrects that but can not be set in this mode the brightness. Is this on your Dell differently?
sorry for my english:)
