Just when we thought LCDs are gradually improving year on year they have sadly taken a massive dip recently. In the past year, S-PVA's black levels have increased from 0.03 cd/m2 to 0.05cd/m2 on average and the viewing angles have dropped significantly. A-MVA's black level hasn't dropped below 0.05 cd/m2 in the past two years. IPS however is making progress but the black levels are still too high (0.10/0.18cd.m2) which makes IPS unsuitable for dark environments. Uniformity in general has also dropped since the introduction of LED-LCD, so did motion quality (instead of tolerable blur, we now have highly visible after images caused by "out of sync" backlight and LCD).
Hopefully next year things may improve on the LCD side, but if you're looking to invest in a display this year, opt for PDP. Even a 1024 x 768 plasma will provide better over all performance compared to 1080p LCD (especially if you're a fan of 60p games such as COD).
