I've got dual ASUS VH236H (2ms 23" 1080p LCD), bought about a year apart. They are great and I highly recommend ASUS. However on one of them the black/white levels are a little different, and the colors aren't the same... but this doesn't really bother me much as I don't normally have the same thing displayed on both monitors at the same time.
The Asus VW266H had ass quality picture. I had a several year old viewsonic 2235wm TN panel that was exponentially better color reproduction, picture quality, and lights/darks as well.
I returned 2 samsung TN panels, and I returned the asus VW266H before I found a monitor I was happy with. So yea, I'm kinda a snob I guess. That said, the VW266H was THE WORST of all the monitors I looked at.
To give the benefit of the doubt, maybe I got a lemon. The whole screen had a greenish hue, that even my wife noticed (and she is not a computer person at all).
I was shocked to see that monitor got such high reviews from people, to find that my several year old 22" viewsonic had a much prettier picture.
