I bought one and promptly returned it I'm afraid to say, could never get the colours acceptable across more than 1 input.
IMO the monitor costs too much for the IQ you get, and you're basically paying a premium for the design and the (IMO) marketing gimmick of LED backlighting. It's nice being thinner than normal and saving a bit of energy, but that's about it.
Not sure where you heard it was "very good". I bought mine on a whim, even though all the reviews I read said it was average. The 27" iiyama I replaced it with is far superior.
