How many hertz is best for a monitor?
Modern display models are characterized by several basic parameters. These are screen resolution, response time and refresh rate. Although, it would seem that the latter characteristic was characteristic only of CRT screens. However, it is also present on modern models, and three digits are indicated in the settings.

What is monitor frequency
At a time when displays took up half the desk space and had a lot of weight, the “refresh rate” parameter, or as it is also called “frame scan”, indicated how often the broadcast picture blinks. It was believed that the higher this figure, the better. This was explained by the fact that with high frame scan values, the eyes were much less tired. At times this figure reached 144 Hz. There were even video cards on sale that supported monitors with a frame rate of 240 Hz.
Modern models have values of 59, 60 or 75 Hz. Where do these numbers come from?
According to existing theory, in order for the human eye to perceive the entire image, the sampling frequency must be at least twice the frequency of the perceived signal.
That is, if an analog signal has a frequency of 25 Hz, this value must be doubled. The MPEG digital signal is 30 Hz. Multiplying the indicated numbers by 2, we get 50 and 60 Hz, respectively.The value of 59 Hz is an average value as the frequency of the AC power supply varies from country to country. For example, in Europe it is 50, and in Russia 60 Hz. All modern video card models are equipped with a system that is resistant to this network interference.
How to find out how many hertz a monitor supports
The value may vary for different display models. Therefore, you need to know how many Hertz a particular display supports. To do this you need to do:
- While on the “Desktop”, right-click on the mouse and find “Display Settings”.
- At the bottom of the menu that opens, select the “Graphics adapter properties” sub-item.
- In it, find “Monitor”, where the value supported by the screen will be written.
ATTENTION! This method is used on Windows 10. On other operating systems, the points may differ.
If you are using the Windows 7 operating system, this is done through the Start menu. Next, you need to go to the “Control Panel”, where you select the “Screen” tab. In it you need to find the sub-item “Additional parameters”.
How many hertz is best for a monitor?
There is no ideal frame rate value, since this indicator is made up of several parameters. Age also matters, because visual acuity gradually decreases. Therefore, in such a situation, the value of frame sweep should be greater.
On the other hand, the graphics adapter is responsible for transmitting the image to the computer monitor. And if the video card produces a figure of 60 Hz, then the display will not show values higher than this figure. If the monitor is set to 60 Hz, and the video card produces a higher scan rate, then so-called artifacts will appear.
Thus, in order to choose the ideal setting for yourself, you first need to know the characteristics of the graphics adapter and monitor. 60 Hz is comfortable for the eyes.
