Re: 120Hz LCDs?
There are two features that come with 120hz: auto motion plus (as Samsung calls it, basically interpolated frames), and 5:5 pulldown.
The interpolated frames gives it a "smoother" look, but many people hate it. I'm on the fence, but most prefer it turned off.
5:5 pulldown is nice though. 60hz panels need to use 3:2 pulldown, since moves run at 24fps, the frames are repeated 3 times, then 2 times, leaving some stutter. Hard to see for most, but it's there. 5:5 pulldown means that each frame is drawn 5 times (24*5=120), so there's no stutter with the motion. This feature makes the 120hz televisions worthwhile IMO.
