I like my new 2408 Dell, and will share this info from another post:
Dell being Dell, there's no hard info on a revision to the panel being discussed by boards and tech reps from Dell (Rev A01). My guess is that it addresses 'input lag,' which doesn't seem much of a problem or at least not noticeable by most. Not by me anyway. Not in my mouse cursor, not in playback of high def quicktime video.
