OP, I'm in a few threaded conversations with other members who are almost killing themselves with frustration with that particular display - the UP2414Q is
junk, and get over the specs. Seriously, just Google "Dell UP2414 problems". If you buy one, "I told you so". You can PM me and I'll pass on at least one of the members I've interacted with on problems with the UP2414Q.
As to the P2715Q, it's a decent display. I have two of them on my desk right now. Give up on pricing - there are so many "deals" on that display from day to day it's rediculous - I bought both of mine for $450, shipped, but I was patient. Also, Dell has discounts for certain members of groups - military, credit unions, AARP, employees of certain companies - and also check "slickdeals.net".
If you don't need a display "today", Black Friday is coming up, there's lots of "back to school" sales, and there's a major "show" going on in Germany right now. Also, Dell is one of the least Mac-friendly companies out there. It's a bit more money but I'm going to buy two more BenQ BL2711U displays for my office next week (we have two now) and pawn off my two P2715Q displays on one of my employees; the new BenQ is sweet...
Oh, and one more thing, don't buy a UP2414Q.
