Re: If people like

Well , since youre the expert, please explain how Hz applies to HDTV's. Because there is a huge obvious difference between 60 Hz and 120Hz, both of which would be higher than 30Hz.

Do cycles per sec equate to frames per sec? Hmm?

I'd like to let this thread speak for me: »fps converted to hz. 120fps = 120hz?

Not really a help, but 60Hz Vs 120Hz+ is totally noticeable, both of which are higher than 30fps

Only in regards to Interlace vs. Progressive.

The point is that 120Hz Refresh exists where no product can yet fulfill. 60Hz would be fine for a 30fps 1080p video, which is what every BlueRay is. Why the overkill with 120Hz? Because new content is being created that can tap into it.

Infrastructure has to be there before the consumer can take advantage of emerging technologies. Anyone who has built their own computer knows this. Will a Core 2Duo work fine for most things? Absolutely. Is the Quad-Core i7 paired with a GTX690 overkill? Absolutely. Is one future-proofed, and therefore justify the build-costs? Only you can be the judge of that.

This is off topic, but according to your info, 120Hz DOES accommodate 1080i, which is the best that stations broadcast at. 60Hz looks like crap compared to 120Hz.

120 is the lowest common multiple of 60, 30 and 24, all of which are common framerates used to display content on HDTVs.

If you try to display 24 FPS content on a 60Hz display, it's not possible to display each frame for a consistent amount of time. Some frames will have to be shown twice, some will have to be shown three time, and as a result the movement will be less smooth (it will jitter a bit).

If you only ever displayed 30 and 60 FPS content (broadcast TV), it wouldn't matter, 24 FPS content (movies) is what throws the wrench in the works.

You could clearly learn a LOT MORE here today if you were willing to listen instead of buying into cablecorps' propaganda nonsense...
