p.s. Jack Bingham does not work in Integrated Color anymore since 2012.
I wouldn't know anything about that, but he still (as of a week ago) posts as "site admin".
Anyway, what I'm trying to say is that one Dell U2713H may work, and the next one not. Yes, they do change their parts in mid-production run. That's how they can sell at the prices they do (which is about half of directly comparable models, spec by spec).
