"It is well known that LCD displays did not until now produce the same deep blacks that were achievable when using a CRT. Color depth is, of course, the 8 bit bottleneck issue. Images on the screen -- at the pixel level -- are limited to a best-case of 256 levels between black and white. In other words, if you painted a gray scale you could, at most, see 256 steps. The reality of the matter is that due to calibration and gamma adjustments most displays can't do much better than about 200 steps between black and white."
Whether or not these claims have any merit is going to be completely up to the customer, and while many including myself still trust a CRT over an LCD for the quickest and most accurate imaging, LCDs are making great progress and soon may be the only choice for even gamers.
