Just a quick question guys, everyone says that you cant turn off 120hz on a lcd. I have been doing alot of research and i am realizing that the only time the 120hz is utilized is either with 24fps bluray or with frame interpolation feature (amp, cinemotion). So if you are watching cable and turn off frame interpolation, then technically t.v is running at 60hz. I am just trying to understand why every one is saying that t.v is always running at 120hz.


correct me if i dont understand it correctly....

No, it's always 120Hz. However, you would only see 60Hz (or 24Hz if you use blu-ray player) on the screen because that is the input signal.

Ok, so display is always 120hz, but with cable signal and frame interpolation off, it would display 60hz? well bluray would be 120hz, because of 5:5 pulldown.

That's why you see 24Hz (24*5=120) for most blu-rays.

120hz is a "REFRESH RATE" which is always on regardless if the signal is analog or digital.

I know 120hz is a "REFRESH RATE", however, if the signal is 60fps, and frame interpolation is not used, then 120hz "REFRESH RATE" is not utilized, meaning 120hz is not always on. correct me if i am wrong....

nevermind, figured it out. Thanks guys. This is taken from ezine articles.


a 120Hz tv will take a standard 60Hz signal and simply replicate it twice which by itself does little to enhance the picture quality. The real difference is made when applying a video processing feature for motion enhancement.
