Still, the HD8000 does a good job, it's just that that performance in this area continues to improve. We are reaching a point, where, for all but the "hard core", many of the differences are slight enough that most just won't care. For example, would I buy the InFocus IN82 over the HD8000? Yes, but I'm pretty demanding. But for most people I know, I'd recommend the HD8000 as a better value, and with picture quality that will still please all but the most picky.
I'll start with a few images that are designed to give you an idea of black levels, then we'll get into shadow detail after that. Overall, blacks are nice and dark, but never quite reach what some would call "inky blacks". Still, for a low cost 1080p projector, not bad at all.
