well, if its not good for color accuracy, I wish they'd market it as a different screen. Its what IPS was known for. TN panels are terrible. the screen on my NEC was the closest to a CRT for me.
That is a common knee jerk reaction to differences in color gamut. Make no mistake about it, even e-IPS is far superior to TN technology. The Dell 2209WA e-IPS is being reviewed by many around the world as being THE best 22" display now.
TNs only have 6 bit color depth and have to synthsize via dithering many of the colors they produce, which is worse by far than an 8 bit panel with a 72% gamut using all undithered colors. TNs have no more than 72% gamut too, but many of the colors in that 72% are synthesized.
The dithering is why you commonly see red/orange blotchy smears on Caucasian faces in darkly lit movie scenes on a TN. Aside from that of course they suffer severe washout at side angles or slightly above center.
The fact is the 20% higher color gamut you get on the full undetuned IPS panels is really only noticeable with very detailed source material like very high res pro photography work, and even then it takes the trained eye of a pro to see it.
In fact the reverse like I've been saying is true too. For a lot of average source material like games and even web browsing, that high a color gamut is going to look overly saturated, meaning bleeding colors.
The only real way to get a high gamut IPS that has good color balance for most uses is buy something like an NEC with SpectraView like Tamlin has and set various profiles for different uses, and that's a very expensive setup that takes a bit of know how and tweaking.
Even with an NEC w/SpectraView though you get noticeably more input lag than IPS panels that are quite a bit more affordable because all the video processing they use slows them down. Thus they are not ideal for gaming if you prefer a display with as little lag as possible.
That's why I said the e-IPS are the best all around. They're great for gaming, movies, web surfing, even amateur photo work, and they're sold at TN prices. I don't think you're seeing the tradeoffs even high end IPS displays can have for average use.
