Dear all, I was on the verge on purchasing a Pioneer plasma when I read in it's specs that it's contrast Ratio was 560:1 (not sure if I have typed it correct). What made me rethink this was because I heard that Panasonic are releasing one with a 3000:1 ratio which sounds very high and better. What I need to know is what do these ratios mean? Secondly is 560:1 low? The TV looked fine in the shop but this has made me rethink. Many thanks. Dave.
