what is the refresh rate on a tv
The refresh rate is the number of frames per second the television can display. Its unit is a Hertz, which is equal to 1/second. 120Hz means it can draw 120 images per second. The refresh rate of televisions is misleading and is mixed with marketing lies. The increased refresh rate (120Hz and higher) was introduced by manufacturers as an indirect way to reduce the motion blur problem of LCDs and LEDs. However, the response time of 120Hz and 240Hz TVs is usually the same as 60Hz ones. Do not look at the refresh rate of a TV. Not only is the advertised number false, but a 120Hz+ TV does not reduce the amount of motion blur in console games. The response time is the best measure of motion blur in an LED TV. It is the time a pixel takes to transition from one color to another.
