Cant see above 25hz? are you for real? lower your screen to 25hz then. Quick google says the human eye sees around that level you quoted but then goes on to say about obviously it can see a difference in motion for higher hz.
Great to know (y)
I think it is a good deal. I was looking for 24 inches, VESA mount, FullHD, IPS and not crazy silly specs (I don't really get why people need 240Hz monitors when the eye doesn't sees anything above 25Hz...). It is also very thing edge so ideal for dual monitor layout.
