What is difference between hz refresh rate of a monitor screen and number of frames fps?
As for FPS value in game and screen refresh rate, I think this is a topic that eSports players are more concerned about. If we need to understand difference between refresh rate and frame rate, then we need to know what they mean! Let's look at it.
FPS frame number
This is typically what we call screen refresh rate within one second. 60 frames per second means that 60 frames appear in one second. The decisive role in number of frames is played by graphics card of computer. The higher performance of video card, higher number of frames, smoother the picture will be.
Update frequency
It usually appears on monitor/screen. For example, I have a monitor with a high refresh rate, 144Hz, which means that upper limit of monitor's physical refresh rate is 144 images per second. It requires monitor panel support and a computer driver. This data comes from output of graphics card.
In this case, we are facing a problem, if video card output is only 30fps and monitor has a refresh rate of 60Hz, what will happen? It's just that image is a little stuck because monitor is set to display 60 images per second, but you can only provide 30 images and same image will be reused.
Then, in turn, my graphics card might be running at 120fps and my monitor is still at 60hz, what happens? The monitor is still displaying 60 fps and extra 60 fps output will be discarded which is an invalid frame rate and will be wasted!
Therefore, there are G-SYNC and AMD FreeSync technologies launched by NVIDIA that can synchronize output frame rate of monitor and graphics card, so you can shoot one and I'll shoot one, and you can shoot two and I'll shoot two. 120fps video card output is used, premise is that display refresh rate is higher than 120Hz, so that game screen will be smoother and smoother.
Therefore, difference between them is obvious. FPS is determined by graphics card and refresh rate is determined by monitor but physical monitor limits performance/upper limit of frame rate and refresh rate The frequency determines number of valid certificates.
That is, if you want to play games at 144Hz, players should select a 144Hz monitor and graphics card should not be bad. If graphics card is too bad, the game can only be played at 60Hz.
