A00 and A01

Get them exchanged.

In your link, you talk about having service tags on the monitors, but I don't see that anywhere, just the 20-digit serial. Am I missing something?

mervis,

You have to read further down in my document to find =

Monitors without a service tag number purchased from Dell 
When purchased from Dell, you receive a Dell Order and Dell Customer number. This order number automatically "registers" you to the monitor and tells the start and end date of the purchased warranty. You cannot register a monitor via the online tools without a service tag number. If you ever need it exchanged while under warranty, you must contact Technical Support for your country and provide to them the following information -

Dell Monitor Replacement Policy and Procedure - Dell Global Policy

The customer is unable to provide a Dell Order Number or system Service Tag because the customer purchased the monitor from a retailer. The only information the customer has is the PPID serial number for the monitor. For monitors where there is not a Dell order number available, agents will use the date code embedded in the monitor PPID serial number to determine the start date when coverage started.

Discussion = The warranty will be 3 years starting from the embedded PPID serial start date on the label.
Solution = Set up the monitor replacement against the dummy tag.
* You would provide the following data to the representative if you ever need a monitor replacement within that 3 year period:
