I am a little confused on this subject. I have played the various test patterns to calibrate my tv and I do not see the blacker than black bars they mention. Is this because my DVD player does not output the signal? Or my TV does not show this? I plan on upgrading all of my equipment when I finish my electrical apprenticeship in a year and a half and I don't know what to look for when it comes to the blacker than black. I don't even know what this means. When I asked a sales guy at a AV store around here about whether or not it was the tv, DVD player, or a combination of both, his reply was pretty much unhelpful. He went over to a TV and turned it off. He said, "That's as black as that tv can produce. You're not going to get any darker." Thank God for this forum!
