Why gaming monitors have a refresh rate of 144 Hz?
Source:Why monitors use frequency of 144 Hertz?
In recent years increasingly found on the shelves of monitors with a refresh rate of 144 Hz picture. What is «refresh rate»? That's how many times the display refreshes the picture per second. 60 Hz display refresh the image 60 times per second. Why do we need it? We are all too lived in the 60 gercovich monitors. In fact, all a little different. The myth that the human eye is able to distinguish only 24 frames — a myth. The same applies to 150 frames, which are so often said lately. The human eye is able to distinguish over 1000 frames per second, and the end is not known the exact figures, therefore, the presence of monitors with a refresh rate over 60 Hz is justified.
FPS and Hertz — one and the same?
No. FPS (framerate per second) — the number of frames per second. The game can work with a number of frames 120, but if the monitor supports only 60 Hz, half the frames are discarded and not shown to the user. And the monitor with a frequency of 144 Hz may not reveal themselves if the game will have a smaller number of frames. Therefore, buying such the monitor, you should think about the fact that the video card in the computer could «digest» game with 144 frames per second.
Why 144 Hz?
And really, why the producers chose the number 120 or 144? Why not 150 Hertz? An interesting question, and the answer lies on the surface. 144 — that's 24 multiplied by 6. All current gertsovki displays are divided into 24: 120 Hz, 144 Hz, 240 Hz, 360 Hz. By the way, today Nvidia in partnership with ASUS display with a refresh rate of 360 Hertz and technology G-Sync. Its sales will begin in 2020, and the cost is not disclosed. But obviously, it will cost obviously more expensive than $ 700.
Nvidia introduced a monitor with a refresh rate of 360 Hz
Why the numbers divide into 24? And where did those 24 frames?
It All started with the time when the refresh rate of the monitor picture directly dependent on the frequency of the electricity. In the United States it was 60 Hz or 59.94 Hz, and in Europe 50 Hz. Where did the numbers 60 and 50? In the early 20th century, the U.S. and several Asian countries have chosen the standard 60 Hz (NTSC), and in Australia and Europe 50 Hz (PAL). The fact that it is starting from 50 Hz, the human eye ceases to notice the flicker of incandescent lamps.
However, the films in the US was done with a frequency of 24 frames. This figure was taken almost from the ceiling in September 1927 by the Committee of nomenclature and standards of the United States. In Europe the film was shot with a frequency of 25 frames per second. Today modern monitors and TVs have a frame rate, which is divided into 60 or 24, just because NTSC has become more popular around the world.
By the way, games in ancient times was developed mainly in USA and Japan, so they are adapted to the NTSC standard and worked with 60 Hz monitors. In this regard, players in Europe could feel the slowing of gameplay by 17%, game developers have adapted their under 50 Hz, but it has been necessary 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 to 1,001, that's why you can meet framerate 59.94 Hz framerate of 29.97, 23,976.
What to expect in the future?
You Can expect the screen update images of 480 Hz, 600 Hz and even 720 Hz. However, this will not happen soon, because the process of increasing personnel hits in the first place by manufacturers of iron — this is a serious challenge. Not every graphics card is able to show without delay 4K video at 60 frames per second, so expect widespread, even monitors with a 360 Hz frequency in the next couple of years is not worth it.
What we have in the end? Due to the popularity of the NTSC standard in the world became popular usage gertsovki, which is divided into 24 or 60. What do you think about this our readers? Share your opinion in the comments section below.
