Re: [Phys-l] 240 and 600 Hz



'Modern' TV's also want to be 'ready' for whatever 3D 'stuff' may be coming down the pike.

The right eye image and the left eye image BOTH need to be smooth.

Another thing I learned several days ago was that the signal delivered by the cable company has the refreshment rate of 60Hz. Higher frequencies are created in TV sets, according to chosen setting.

Some new High Definition TV sets are designed for very high image
refreshment rates, such as 240 Hz and even 600 Hz. This seems to be
unnecessary; the refreshment rate for traditional movies has been 30
Hz. Because of this I think that anything above 60 Hz is just waste of
money. Do you agree?
