# Why do game monitors have a refresh rate of 144 Hz?

Recently, more and more often can be found onstore shelves monitors with a refresh rate of 144 hertz. What is the "refresh rate"? This is how many times the display refreshes the picture in one second. 60 Hz displays refresh 60 times per second. Why is this necessary at all? We all lived well with 60 hertz monitors. In reality, everything is a little different. The myth that the human eye can distinguish only 24 frames is a myth. The same applies to the 150 frames that have been talked about so often lately. The human eye is capable of distinguishing more than 1000 frames per second, and the exact numbers are not known to the end, so the presence of monitors with a frame refresh rate of more than 60 Hz is justified.

Why are monitors using a frequency of 144 hertz?

FPS and hertz - the same thing?

Not. FPS (framerate per second) - the number of frames per second. The game can work with a number of frames of 120, but if the monitor only supports a frequency of 60 Hz, half of the frames will be discarded and not shown to the user. And at the same time, a monitor with a frequency of 144 Hz may not reveal itself if the game has a smaller number of frames. That is why, when buying such a monitor, it is worth considering that the video card of your computer can "digest" games with 144 frames per second.

Why 144 Hz?

And indeed, why manufacturers choseexactly the number 120 or 144? Why not 150 hertz? The question is interesting, and the answer lies on the surface. 144 is 24 times 6. All current display hertzs ​​are divided by 24: 120 Hz, 144 Hz, 240 Hz, 360 Hz. By the way, today the company Nvidia in partnership with ASUS introduced a display with a refresh rate of 360 hertz and G-Sync technology. Its sales will begin in 2020, but the cost has not yet been disclosed. But obviously, it will cost clearly more than \$ 700.

Why are the numbers divided by 24? And where did those 24 frames come from?

It all started from the time when the frequencyMonitor image updates depended directly on the frequency of electricity. In the USA, it was 60 Hertz, or 59.94 Hz, and in Europe, 50 Hz. Where did the numbers 60 and 50 come from? At the beginning of the 20th century, the United States and several Asian countries chose 60 Hertz (NTSC) as the standard, and 50 Hz (PAL) in Australia and Europe. The fact is that it is starting from 50 Hz that the human eye ceases to notice the flickering of an incandescent lamp.

At the same time, films in the USA were made with a frequency of 24frame. This figure was taken almost from the ceiling in September 1927 by the US Nomenclature and Standards Committee. In Europe, films were shot at a frequency of 25 frames per second. Today's modern monitors and televisions have a frame rate that is divided into 60 or 24, simply because the NTSC standard has become more popular throughout the world.

By the way, games in ancient times were developed inmainly in the US and Japan, so they adapted to the NTSC standard and worked with 60 Hz monitors. In this regard, players in Europe could feel a 17% slowdown in gameplay, game developers adapted them to 50 Hz, but this led to the need to rewrite the code and the appearance of bugs in games. And in order to fix the problem with sound, it was decided to divide the frame rate by 1.001, which is why you can find the frame rates 59.94, 29.97, 23.976.

What to expect in the future?

You can expect update screens to appearpictures of 480 Hz, 600 Hz and even 720 Hz. However, this will not happen soon, because the process of increasing staff primarily affects iron producers - this is a serious challenge. Not every video card is capable of showing 4K video at 60 frames per second without delay, so you should not expect widespread distribution of even 360 Hz monitors in the next couple of years.

What do we have in the end? Due to its popularity, the NTSC standard has become popular all over the world using the hertz, which is divided into 24 or 60. And what do our readers think about this? Share your opinion in the comments below.
