Bought a Vizio E470i-A0. Is it really a 120hz tv or is it 60 with software that makes it "120"hz tv. Been thinking about returning it and picking up a samsung un46es6150f, not sure. I am not that impressed with internet features and the sound. It also doesn't want to work with my Bluray player. Looking for some feedback, when I got it, I was impressed with the price, but using the blu ray it didn't have a picture that like my philips and other 120hz tvs.
