Speaking from experience, I've had the Samsung BX2450 for a few weeks now. Overall I would say I'm pretty happy with it 4.5/5 if I had to rate it. Though here are some things that should be of some concern. I used to use an old hot Westinghouse L2410NM which did have a VA panel. Being an LCD I believe it has the CCFL backlighting, which on a side by side comparison with my Samsung, kind of puts the LED white spectrum to shame. This appears to be a problem inherent in LED monitors as I actually bought an Acer 23" a month ago, but the blue hue whites put off on that monitor were hideous. The Samsung however, though not perfect, does a much better job of fending of the typical blue hue of LED backlighting.
Essientially, if you've been dealing with TN panels this Samsung will appear very bright with some nice rich colors, though you'll have to adjust some settings. By default my 2450 was fairly bland with some grainyness to it. After a couple weeks though I found my ideal settings. I used the "magic angle" setting I believe and set it to "wide" or "group", I forget the name. It automatically adjusted the colors/contrast etc to get the richest colors without a whacky contrast/brightness adjustment. Basically it can get pretty close to what my old VA panel Westy looked like, which is pretty impressive for a TN panel.
Another really weird issue was in the "response time" setting. I think it was backwards so to speak. As I increased the speed e.g. normal/fast/fastest I actually noticed ghosting, and really bad ghosting at fastest. Leaving it on normal though, zero ghosting that I can tell. Weird.
Overall If you haven't been spoiled by higher end panel type monitors, these Samsungs are a home run (go for the 24").
