A:AnswerVizio uses their own terminology called Effective Refresh Rate which just takes the actual refresh rate and doubles the number. This means an Effective Refresh Rate of 120 is just a 60Hz TV. So this TV has a native refresh rate of 60.

A:AnswerNo headphone jack, but it does have red/white RCA and optical for audio out. And the TV has bluetooth, but only for pairing your phone to use it as a remote and connect it to the internet.
