This is a good quality, reasonably priced monitor. Picture is sharp and clear and the build quality is good. Stand is easy to attach and very adjustable. The bad news is the 3 year warranty is very hard to register with Dell. To do it on line you need a "service tag" - there isn't one. Amazon buy this item in bulk from a third party - in my case a dealer in Istambul, it seems, so no real surprise that Dell has no record of it. So it means hanging on the line to Dell and trying to pursuade them to register the warranty. Dell don't seem very keen on you buying from companies like Amazon who are described as "shelf stackers". Here is the advice from Dell on how to register the warranty:
Contact Dell Order Support for your country. The Order Support agent will need to submit a Fusion request to the CTS Retail OPS queue to get a Dell Order number attaching you to the monitor. They will need the following information to fill out the form -
Online Retail Store:
Purchase date from Online Retail Store:
Monitor 20 digit PPID number (on the back of the monitor)
Good luck - you may need it.
