Am I the only one confused by contrast ratios? I see them mentioned in magazines and on websites. Even in these forums they are often quoted but do they mean anything? Panasonic claim to have contrast ratio of 4000:1 while in HCC I see that most ratio are stated below 400:1 (most much lower) So is panasonic being economic with the truth? what about those others with claims of 3000:1 or 1000:1 are these just exaggerations? why isn't there a standered that us regular Joes can understand.
