Well, I've just taken a punt on one [a bit rude not to, at that price!], so let's see.
From what I've been able to research, pretty much every 27-incher out there has noticeable return rates, if forums are to be believed. And while every panel is different, if my experience with an Asus PA246Q I use at work is anything to go by, I'll be more than happy with this. Seeing as it's replacing my venerable Dell 2405FPW [7 years old, cost over £700, already been through one power board
], I'm pretty confident it'll be a worthwhile purchase.
My only concern is how my eyes will react to LED PCM, seeing as I've only ever used CCFL-lit screens so far. Fingers - and not eyes, hopefully - crossed, eh?
