Buy the LCD that provides the best black and ability to see detail in shadows. I think they call it contrast ratio. Beware that the stores will generally use the mfg. settings which tend to be too saturated to look good in store lighting. In any event it is hard to hide a TV that does poorly showing detain in dark shadows. I have found that Samsung and Sony do the best in Contrast ratio in a real environment. In general you get what you pay for. Sony does charge for its name more than Samsung does. Samsung uses it own glass while Sony will purchase others glass and use it own electronics. Philips is a major stock holder in Samsung and markets other well known brands. Some Philips/Magnavox have a good contrast ratio as well. Toshiba is decent in some models.
It is a zoo, so go by what you see in the contrast ratio in dark or black background. Maybe compare them to a plasma which has better contrast ration in most cases. Unfortunately plasma tv eats a lot more electricity. You can't hid a pig--sort of speak. Oh yeas, watch the motion blur which is non existent in 120 hz tvs but the cost goes up. LCD response time comes at a price.
