I had problems getting Dell customer service to help me because they expect the monitor to have a Service Tag number or for you to have a Dell order number

There was of course no Dell order number, either, because the monitor was bought from a retailer, not Dell.

I had to call them three times (and ignore a thread in their forum where their "liason" misinformed me) before getting an employee who would deign to entertain my questions without an order number or service tag, finally a tech rep acknowledged for me that yes, the manufacturer's 3-year warranty (from time of manufacture at rear) remains valid despite my inability to obtain an order number.

When I called back with this order number, the CSRs said it was useless to them and they need a "service tag" number.

The tech support person created an "order number" for my monitor based on the serial number, which order number allegedly I could use in the future to access warranty service and tech support.

Dell's reps repeatedly told me that they cannot transfer me based on a serial number, or a Dell order number.

I guess I will open a customer support ticket instead, but no, this requires an order number, which of course I do not have since I bought it on amazon

Returning them and getting the correct U replacements was straightforward, although cumbersome (this was an order of 14 monitors, so could have been worse).

If I had it to do over, I would still buy one of these again and recommend the U2412M to others looking for a reasonably priced monitor with great performance.

This is revealing, since when emursing myself in reviews for monitors, I started to feel like the 2412M would be a 'compromise'

I'm not a techie, but I did need a big screen for work, researched what was out there thoroughly, took it all in, and landed on the Dell Ultra Sharp U2412M 24-inch

Overall, I highly recommend the U2412M as its the best bang for your buck for an IPS monitor in the $300 range.

We have developers and support staff using them and they love the U2412M.
