How do I know the refresh rate of my PC monitor? – Hertz


If you have seen reviews on technology websites, you have probably heard about the refresh rate of a monitor or screen. But what is the meaning of this parameter, how do I know the refresh rate of my monitor, and can I change it? These questions will be answered in the following lines.

The refresh rate is a parameter used in visual output devices (monitors, tablets, cell phones, etc.), it represents the number of times the image we see on our monitor, cell phone, among others, is updated.

This measure is expressed in cycles per second (Hertz), i.e. if the refresh rate of our monitor is 144 Hz it means that the image is updated 144 times every second.

How many Hertz HZ should a computer monitor have?

For many years the refresh rate of monitors was set at 60 Hz, however there are currently devices in which you can adjust to other values such as 90, 120, 144 Hz even there are high-frequency with values higher than the latter as are 360Hz, so the Hertz of a computer can vary according to the monitor model and date of manufacture.

High frequency devices are generally used in gaming activities, where the response speed and the information provided by the monitor are of vital importance to avoid delays in the response, although the flickering of the screen cannot be detected by the human eye, it will influence the information presented to the user.
