The 75 Hz or 100 Hz, etc., stated in a television's technical specification, means the picture refresh rate in cycles per second.
The higher the picture refresh rate, the better the display of small fast-moving objects can be. (Footballs or tennis balls in flight, etc.)
That means that whatever that wave is, whether it be a radio or television wave, is moving up and down 150 times per second.
The jvc 42 LT42PM30 lcd tv has 60 hertz.
The main problem is that the picture transmission standards are different in different countries so that in general TVs do not work in that situation.
If you've been walking through the local electronics store, or browsing HDTVs online (and I'm sure you have), you may have noticed a lot of attention being payed to "120 Hertz," that is, the refresh rate of some newer model televisions. The refresh rate refers to the frequency with which the image on the screen is updated, or re-drawn. "120 Hertz" means that the image you are looking at on the HDTV is updated 120 times a second.
no because the tv can only pick up siginals at 60Hz if the signal is 50 Hz it won't pic it up.

I believe this hertz car rental has some paperwork to its name for you to sign. The agreement existing is mention in the TV ad for the product. That is my evidence for you.
Hertz symbolized as Hz, describes the refresh rate of TVs.
The higher the better if for use in USA.
Hz probably means Hertz. It's an unit that describes how many times each second something happens. Hertz is frequency of some wave like activity e.g. sound wave, light wave, etc. Long ago, the scientific units of measurement were descriptive; for example, "one horsepower" referred to the power that one horse could generate. Then "they" (the "International Electrotechnical Commission") decided to name all the units systems in honor of various scientists and discoverers. One "Hertz", named for Heinrich Hertz, is one cycle per second.
he invented electronomiical telegraphs that once became a tv!yea awesome right well then he became a fashion moldel
hertz. it a frequency measurment.
