The best thing I liked is Dell warranty and RMA service, sadly but my U2713HM has 1 dead pixel and 3 half dead pixel with bright yellow glow at bottom left, REV01 too, don't tell me REV01 is perfect without flaws, that's bull**** lol(no offense), sure have minor flaws with BLB or Glow at either 30% or 100% brightness, there's ways of testing it but I don't recommend if you guys don't see it at normal usage.
I was commenting at Overclock.net U2713HM thread and all of them RMA at least once or twice, so there's no perfect panel for U2713HM, even Dell support team knew all these problems, and it's origin from LG Panel itself, just isit very bad or not so bad or how user can accept it.
Rumour that there's REV02 coming out, I'll see if I receive a REV02 next week for my new replacement and let you guys know.
