I did read somewhere that they're leaving some component out of IPS screens these days, something like a polarizing filter, to reduce costs and it means the viewing angles aren't as good as the IPS screens from 5 years ago.
Certainly the 4 IPS screens I've owned fit that theory - I had a Dell 2007WFP (my Dad uses it now, still going strong) and an LG 32LC2D 32" HDTV (again still working) which both had awesome viewing angles and were bought around 5 years ago, but the Dell U2312HM I just bought and the Panasonic 37" TX-L37S20BA I've bought last year, while cheaper, can't quite match those old screens for viewing angles.
Maybe Baddass and PCM2 would know more about this, it's just something I read on AV Forums.
Trouble with going VA, they don't seem to be quick enough for gaming.
Btw that U2412M backlight doesn't look right to me. Ok mines the smaller model, but there's nothing anywhere near that bad.
