But if you sit very far from direct front you get a color shift. I've noticed this on my 24" LCD computer monitor. 170 degrees might be claimed, but 90 degree is more like it.

Also, besides the fact that they don't go full black, they also dont do dim well. Everybody talkes about max contrast, but LCD doesn't have the range to do lowered contrast well. All the contrast makes for a punchy image, but there's also the problem of eyestrain. Philips has LCD monitors that use ambilight tech that works very well to aleviate this problem.
