Just uttering the word "calibration" around an HDTV newbie will either elicit a blank stare or a lowered head. Nah, that hasn't been scientifically proven or anything, but we'd surmise that most folks avoid advanced tweaking for fear of screwing something up or just wasting too much time and effort. Thankfully, CNET has started up an HDTV picture settings database, which will show viewers the optimal setup they found on each set taken in for review. Granted, this means that not every single set will be there, and there's still aways to go before it's really fleshed out, but it's not a bad resource for $0.00.
