Not quite sure myself but heres an article i dug up that might bring some insight on the subject.

I've read that article though... I still find myself lost in the 120Hz+Automotion plus world...

Since i'll be doing everything on PC...

I want the Auto motion plus / 120Hz to be compatible with PC...

Thank you for your help though!!!

Hi Everyone...

I'm thinking of buying a HDTV (Samsung LN40A650) that offers 120 Hz / Auto motion plus...

I will be using it as my PC-gaming monitor and be using it with computer most of the time

I've got two question...

1: Does PC-gaming/PC-movie benefits from 120Hz

2: Does PC-gaming/PC-movie benefits from Auto motion plus

Thank you everyone!!!!
