ACD's are limited on features and warranty length, but they are built with superior IPS
panels which you will not find in any other monitors at comparable or lesser price.
20" ACD ........... LG.Philips LM201W01, 1 yr warranty, 1 video input, $599
Dell 2007FWP .... LG.Philips LM201W01, 3 yr warranty, 4 video inputs, $399
Plus a half dozen more from Philips, Acer, LG -- all with
exactly the same
LM201W01 panel -- with better warranties, and multiple video inputs, and
features like picture-in-picture, and
significantly less expensive than ACDs:

Run the same search on 23" and 30" ACDs, and you'll find the same results.
Sony, LG, BenQ, ViewSonic, HP, Philips, and others all offer monitors with
exactly the same LG.Philips panels (i.e., same part numbers) as the ACDs.
There's nothing "exclusive" about ACDs -- except high prices, zero features,
and crappy warranties.
Nearly every competing monitor on price uses PVA panels, which are of
lesser quality and cost. If you want to understand the differences, do some
online research.
I guess that's why ultra-premium professional monitors from the likes of
Eizo use predominantly S-PVA panels, huh? Try some online research at
slightly more depth than "all about LCDs in 1000 words or less" and you
might discover that S-IPS is not inherently superior to S-PVA. Both have
their advantages and disadvantages -- and many of the best (and most
expensive) professional monitors use S-PVA panels.
