differences between Hanns G 28" models?

[breakspirit]

Hi guys, this is my first post here, but everyone seems very knowledgeable, so I thought this was the best place to ask this question. Could not find the answer elsewhere, so forgive me if this has been asked before.

Anyway, there's three Hanns G 28" LCD models for sale on newegg, with the following model numbers:

HZ281HPB
HH281HPB
HG281DJB

The HG model says it comes with X-Celerate Technology which I assume is marketing BS but is also 60 dollars more expensive. Any info on what the real differences are between these models? Thanks.

I've seen people say that the HH is the newer version of the HG, despite being cheaper in price. No word on what the HZ model is though.

I would check to see which of those models is capable of 1:1 pixel mapping, a handy feature for a 16:10 1900x1200 monitor imho.
