What's the difference between these Dell U2414H monitors?

Question

Monitors

Hi all. I want to take a monitor for programming. Most of all I liked the Dell U2414H . Its average price is 7500 UAH, but there are much cheaper options. For example U2414H (210-ADUL_W) or Dell U2414H (860-BBCW) , but I'm confused by the markings in brackets.
Does anyone know what is the difference between these three monitors?
Thank you.

Here I would not take it at all. The site is suspicious, of all contacts only a mobile phone, nothing from the office. They will bring with a glued label, then you will not find them.
(ADUL_W) - it is not clear why it is cheaper. It seems that it should be the same monitor, but you call this algol - they just could have an outdated price for a non-existent product on their website.
In general, it is better to take expensive equipment in large online stores so as not to fall for fakes.
