It's not like a monitor has a lot of ways to check its identity in a unique way

It does.

Some monitors have a model number, version code, part number, manufacturer date, patent number, and the list goes on.

But would they even check that? I don't think they write down the serial number of whatever monitor they send out, so if they get one back and it's the same model (just not so new anymore) it shouldn't really matter, at least that's what I thought
