im currently using the samsun 997df and its a pretty nice monitor. there are a lot of little quirks that would make you think twice though.
first of all, its quite difficult to get the geometry right, and you're almost gauranteed to have a slightly curved edge, since the only reason that the monitor is a flat screen is because the glass is flat, so basically it just curves out the image.
secondly, and this one is probably the thing that bugs me on a regular basis, is that there is a loud oscillator whine when displaying certain colors on your screen. typically, i hear it when seeing white on black or black on white. this is at 1280x1024 resolution btw. at this res, the refresh rate is actually supported up to 85hz, but the noise while viewing those particular colors becomes pretty much unbearable. i use it at 1280x1024 @ 75hz, and though the noise is still pretty audible, at least its not as bad.
anyway, what im saying is if you can bear the noise then go for the monitor, it's too much of a pain in the ass for me to return it to samsung so i cant really do anything about it for now. it's also a pain that the nearest monitor service center for samsung is about 300 miles *points somewhere* thataway.
