I Don't Understand the Differences between these 4 monitors

[SkyIer]

So I have basically settled on buying a Qnix Qx2710 and I just don't understand the differences betwen these 4 monitors variations.

 

They are all on newegg, through the same vendor and for (almost all) the same price. Is there a difference in the actual hardware save for the different ports on some of these models. Anyone care to shed some light on this (and brownie points for pointing our what the best one is if there is a non-port difference).
