I bought my monitor last month, went for the HP LP2475W in the end, what swung my mind was the reviews on tftcentral, this is the conclusion on the NEC
"NEC have pulled out all the stops here to make the ultimate multimedia screen, and they have come pretty close compared with the competition. There's certainly a massive range of options, features, extra modes, ergonomic adjustments and interfaces. There's about everything you could need, and I was particularly impressed by a few nice extra things like the remote control, ambient light sensor and through mode. These were all very welcome additions to the 24" market, and not something you see commonly at all. Here's hoping more manufacturers follow suit! There were a range of other features with more 'questionable' use, but at least they have included them for those who might find them of benefit.
Performance wise, ignoring the massively overly bright default settings, the screen performed pretty well in terms of colour accuracy, black depth and contrast. Calibration produces some very pleasing results as one would hope, and this is probably expected from an AMVA panel. Combine this with the wide viewing angles, decent input lag and respectable responsiveness, and you have a very good all round screen here! I'm sure some people will gripe that it's not IPS, or that they wanted a wide gamut screen, but if that's the case, maybe the HP LP2475W would be a better choice for you. If you want a multimedia screen, with a very impressive range of options and features, this would make an excellent choice."
