On the Unit itself? It seems to me that after I put the contrast and brightness both to -7 it resulted in the best black levels on my monitor. I have a toshiba 50h81 that was isf calibrated for a jvc dvd player, and when I had to get a different player, it always struck me as the black levels were bad, but the picture was better. Now that I set the black level and brightness to -7, the picture is 100 times better! Chime in with your responses and test out my theory.
