1080p at 27'' can be a no-no but i guess the 400$ price tag makes up for it.
VG259QM which is the same monitor but 25" seems to be non-existence in Australia at the moment. 25" is slower than 27" according to one user on Blurbuster forum but i don't know how accurate this statement is. They bought both models n tested it themself.
280 Hz??
