I appreciate you listing the specs for the Panasonic TC-P50S1. They're great, the only problem I've encountered is that in the advanced settings menu, the option for "Black level" is set to dark, and it's grayed out. Is there a way that I would somehow be able to adjust this, because the TV looks great, aside from the black being slightly too dark? Thanks
