How big a deal is the 120 hz feature on new TV's?

It's a big deal.

For me, someone who watches lots of movies, the greys, blacks and shadow detail aren't good enough yet - they're better on SOTA LCDs like Sony XBR and Sharp, but they're not quite good enough yet for me. Plasmas still beat LCDs hands down for shadow detail and deep blacks. My other hassle with LCDs is the viewing angles.

If you're not a movie watcher then you might be very happy with an LCD.

What LCD/size monitor do you guy's use for PC? Since Samsung's are dual purpose, they seem to be a good buy(especially the 32")...yummy.

I am curious about this too as I am currently shopping for a LCD.....

I think 120 Hz might pertain to other technologies as I saw it as a feature on a Samsung DLP.

Well,

I saw the difference today, quite noticeable. There was a Nascar clip on and the were streaming the leaders names across the scene. You could see how much smoother it was with the 120 hz "smooth" feature the Samsung had. What is it called, Auto Motion Plus (AMP) or something?
