Because I went from a plasma to this TV. I have never had a smart TV it took a while to get used to it and how to get the most out of it, it's was very confusing. It's like always owning and playing on a Xbox for all your life and then suddenly getting a PlayStation, they are basically this same thing, do the same thing have the same games but at the same time completely different and take time getting used to. It's like digital clean view setting on the tv, I don't know what it is and still don't but I know the TV looks better without it lol, the thing I really like about the TV is the dimming it's really good when watching films
