The reason for 120Hz is very simple. If you want to watch BluRay media that has the 24p film option then you want the 120Hz screen. Sorry but I'll keep this short as the way is a bit over discussed. It's simply that 120 can be evenly divided by 60 and 24.
I want a 32 in bedroom tv but im not sure if I should go for a 120 hz or 60 hz which seems to be what most 32inch flat screen models offer. A few years ago I was told with a screen that size it 60 vs 120 did matter. Help please.
