For the backlight types, the first
things you want to do is (1) turn
the backlight down from full, to
about halfway, and (2) under
advanced settings, turn off
any "eye candy" - garbage like
skin tone enhancer, black level
enhancer, edge enhancer, and
digital noise reduction.

Next, get the TV out of "Vivid"
picture mode. All that is designed
to do is shorten the life of your TV
so you can go out and buy a new one
in 3-4 years(!).

I did that (except I realize I left noise reduction on) and I get a kind of washed out appearance, like water colors instead of oils. I left it that way to see if I'd get used to it. My wife and daughter have not commented - really they watch the majority of TV. But I didn't tell them what I did, I'll wait a day and ask.

What made the most difference was removing Vivid.
