Sorry, I found a thread further down that explained the 120hz thing. I still don't fully understand the AMP feature and settings though.
I have some questions that will probably seem very dumb, but I recently purchased the LN46A650 model largley so I could have the 120hz for video games and Blu Ray. Whenever I go to play a game (Playstation 3 hooked up via HDMI), or anything really, it never says 120hz at the top left of the screen (it's usually 60hz or in the case of a Blu Ray, 24hz).
I also had a question about the AMP. I don't really understand what it is, and what exactly the different level settings do differently from one another?
Sorry if these questions are answered somewhere else.
