I just bought a 2nd hand 2407wfp, and all I want to do is check if theres a warranty. That apparantly is not humanly possible. If I look online they need the mythical service tag of legend, (as you said, doesnt exist on monitors), and if I ring up they give all these options. None of which are monitor so I picked "other Dell branded products" and it sends me back to choosing if I have a desktop, laptop or server. NONE OF THEM PLEASE. Then after it says the offices are closed. You could just tell me that at the start, no?
