Hz Question
Whats the difference between 120 Hz and 240 Hz ?
For TVs, the number of Hz (hertz) measures the screen refresh rate, which is how many times per second a TV screen image is completely reconstructed. A TV with a 60Hz refresh rate means that the picture will be completely rebuilt 60 times in one second. Generally, the more the screen is refreshed, the smoother the images will appear to the human eye.
