Ha, I've been looking intently for green where it shouldn't be. I thought
maybe there was a hint of green in Alton Brown's hair on the Food HD channel but it was probably just the fact that there was a green grass background and you're seeing through the wispy hair on the top of his head.
So far things mostly look very good. The default Sports picture mode is WAY too bright and actually hurts my eyes.
I went round and round with the decision of size and I think 52 was probably the right choice but even at 11 feet viewing distance the HD channels look like they are zoomed in and the whole screen is in your lap. I can't imagine having a 73" TV at my seating distance like Greg Gable but who knows, over time I may start to feel it's too small.
