Is the Sony BRAVIA KDL42EX440 60hz or 120hz?

on amazon it says 120hz but then on best buy it says 60hz?

Thank You!

One of them is wrong. I check the sony's website I can find power requirement frequency is 50/60 Hz, but there is not the refresh rate. And I found other review said it has the 120Hz refresh rate.

I think Best buy maybe wrong because that is their way to do the business.
