What Is The Term ‘Refresh Rate’ Used For?
The term refresh rate is to determine how many times a TV is capable of changing the picture on its screen within a second.
For instance, if a TV has a refresh rate of 60 Hz, it means that this TV can refresh or change 60 pictures per second. And the TV having 120 Hz will be capable of refreshing 120 images each second.

Difference Between The Terms ‘Refresh Rate And ‘Frame Rate’:
The terms refresh rate and frame rate are different from each other. The refresh rate defines the capability of displaying devices like TV, while the frame rate talks about the quality of the video source.
Refresh rate shows the maximum number of pictures a TV can display per second. On the other hand, frame rate gives the maximum number of frames the video source can provide for display per second. The word frame means the still pictures that make a video. As we know that each video is a collection of many still pictures.
The Connection Between Refresh Rate And Frame Rate:
For a better and smooth display of a video, the refresh rate of the displaying device must be equal to or greater than the frame rate of the video source.
Let’s suppose if the video source has a very high frame rate, but the displaying device has a low refresh rate. In this case, the display will not be good quality. And there will be problems like lagging and lack of smoothness.

Types Of Refresh Rates:
1. 60 Hz:
Most TVs, nowadays have a refresh rate of 60 Hz or 120 Hz. We will discuss the first 60 Hz.
A TV with a 60 Hz refresh rate means that it has the capability of showing or refreshing 60 images every second. This refresh rate is good for watching movies as the majority of the movies these days are produced at a 30 fps source.
A TV with a 60 Hz refresh rate can easily tackle movies of 30 fps and display them in a way that simply displays each frame twice. But the problem arises while displaying a movie produced at 24 fps. And it is just because 60 is not the double 24 and therefore, frames can’t be displayed twice.
2. 120 Hz:
TVs with a 120 Hz refresh rate are more reliable as they can handle both 30 fps as well as 24 fps movies. It can be simply understood as a 120 Hz TV or other displaying device that can display frames four times and this can easily tackle 30 fps movies.
When it comes to the 24 fps movies, it can simply display each frame five times and can display 24 fps movies equally. While 240 Hz is simply double 120 Hz and may have side effects like the soap opera effect which results in giving your picture an unreal or unnatural look.
