Guys,
I wanted to share this with you all, I took the plunge and bought the C650

I had been to Best Buy/Sears 3-4 times, and couldn't decide which I like better (46C650 vs 50PK750), so I decided to try out the C650 at home (during the 30 day return policy) before making my final decision.
The reason I have to rely on you guys to guide me is that I've not watched TV for the past 6 years, so I don't have a baseline as to what to expect from a LCD/Plasma.
Here's are 2 questions from my 1st impressions:
Moving ~45 degrees from the center, I do notice the colors go off a bit. If I focus on the grass (on a football field) or people's faces, and then move ~45 degrees off center, I notice the colors go a little dull.
1. Is this okay/normal/acceptable? For you guys, does this affect movie experience if you are on the couch's edge?2. With lights on, the image/picture looks good. But with lights off, not so good, the screen looks a little dull, not vibrant.
Do I need to change some setting for dark room viewing?
