Many of you have probably already seen the new Televisions advertising 120Hz. Even though the number is double that of the previous televisions playing at 60Hz does it really make it twice as good?

A quick explanation of Hertz is the refresh rate at which the screen reconstructs the image per second or better known as frames per second (fps). So a television with 60 Hertz can display 60 different images per second. A television with 120 Hertz can display 120 different images per second.

The problem with such high framerate per second is that television broadcasts at only 30 frames per second. So with a 60Hz refresh rate it will simply repeat the image twice every second and with 120Hz it will repeat the image 4 times every second. So assuming you have to completely identical tv’s, one playing at 120Hz and one playing at 60hz, you will not be able to tell a difference.
