It is if you watch sports.
The higher the Hz on your TV, the more fluid the pictures will seem to your eye. In general, a higher refresh (Hz) rate is better, but you might not be able to tell much, or any difference depending on what you're watching.
There are many companies that have created a 100 hz or higher lcd screen for their televisions. Sony KDL32D3000 LCD TV is current in the number one position for have the best 100 hz television.
600. Absolutely.
100hz means the picture on the tv is refreshed 100 times a second. The higher the hz the more frames per second which results in a smoother video.
Yes !
A standard 60 Hz TV cannot be increased to 120 or 240 Hz due to limitations with the equipment. These higher refresh rate televisions are specifically built this way from the factory and offer no upgrade options for older models.
hz or more correctly Hz is a unit of frequency meaning cycles per secondhtz is a common misspelling of Hz
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.)
Ultrasonic. Or do you mean what causes them : all types of electrical machinery including TV sets, humming birds, mice (singing) insects.
Higher notes have higher frequencies. A typical tuning fork vibrates at 440 Hertz. That's the tone of the A above middle-C on a piano. The A one octave higher is 880 Hz (2 x 440 Hz). The A one octave above that is 1760 Hz (2 x 880 Hz). The A below middle-C is 220 Hz (440 Hz ÷ 2), the next lower A is 110 Hz, and so on. The lowest note on a piano is 27½ Hz, and the highest is 4186 Hz.
560 Hz has a higher frequency than 7.83 Hz. "Stronger or weaker" cannot be determined from frequency alone.
Hertz symbolized as Hz, describes the refresh rate of TVs.
