How to see the Hz of the monitor

You have witnessed a computer debate between two friends of the sector and, listening to them, you have discovered the existence of the refresh rate : measured in Hertz (or Hz), this value strongly affects the fluidity of the images displayed on the screen and is very important in the gaming field .

Wait, are you telling me that now you are curious to know how to see the Hz of the monitor in your possession, to understand if it is suitable for gaming or not? In this case, know that you are in the right place: in the following bars of this guide, in fact, I will take care to explain how to find this information on both Windows and macOS.

So, without waiting any longer, make yourself comfortable and read carefully everything I have to explain to you on the subject: I’m sure that, at the end of the reading, you will have acquired the necessary skills to reach the goal you have set for yourself. Having said that, there is nothing left for me to do but wish you good reading and have fun!

Preliminary information

Before getting to the heart of this guide, let me give you some more information about the topic you are interested in.

The Hz monitor, to put it simply, match the refresh rate , or refresh rate : This parameter, measured precisely in Hertz ( Hz ) represents the number of updates per second performed by the screen. To give you an example, a monitor with a maximum refresh rate of 60 Hz is able to “redraw” the content displayed 60 times per second.

In the past, the refresh rate significantly affected the functionality of monitors: on CRT screens, in fact, a very low refresh rate corresponded to a display flickering clearly visible to the naked eye. For this reason, over time, much higher refresh rates have been introduced, in order to reduce that annoying problem.

On LCD monitors, however, no screen flicker is visible, at least not to the naked eye, even at low refresh rates. However, this value strongly (but not exclusively) affects the fluidity of the images shown on the screen: the higher the refresh rate in use on the monitor, the smoother the image .

It must be said, however, that the final rendering of any “moving” content (eg the sequences of a game) does not depend only on the frequency of the monitor in use, but also on the type of connection of the same to the PC and the frame rate (or playback frequency ) supported by the video card : this last value indicates, specifically, the number of frames that the GPU can process in a second, to compose an animated scene.

Unlike the refresh rate, the frame rate does not have a stable value and varies according to the complexity of the scene, the processing power of the video card, the technology in use and numerous other parameters of a technical nature.

It is for this reason that, in order to avoid artifacts or visual problems, video giants such as NVIDIA and AMD have introduced technologies such as G-Sync and FreeSync , able to “align” refresh and frame rate at any time, so as to obtain sequences fluid in reasonably low times, and without artifacts.

Generally, a common PC monitor is able to reach refresh rates of 60/75 Hz; however, some panels, especially those designed for gaming (and, in general, for streaming content in a rapid sequence) are able to reach and exceed 120 Hz and to obtain frequencies equal to 144 Hz or even 240 Hz .

So, if you are going to buy a new monitor and you want to know, in advance, the maximum refresh rate that can be reached, you would do well to check the technical data sheet of the screen : the refresh rate value, in Hz, is clearly indicated between the hardware features.

If, on the other hand, you already own a monitor and would like to know the maximum refresh rate supported, carefully follow the instructions that I am going to give you in the following chapters of this guide.

How to see the Hz of the monitor on Windows

Having made the necessary clarifications, the time has come to understand, in practice, how to see the Hz of the monitor – or rather, know the refresh rate – using the tools offered by the Windows operating system .

Without a doubt, the easiest way to get this information is to use the Microsoft operating system settings panel. To begin, therefore, open the Start menu (by clicking on the flag symbol located at the bottom left), go to the area dedicated to Settings , by clicking on the gear- shaped icon on the side of the menu that has opened and , then go to the System and Screen sections .

Alternatively, you can reach the aforementioned screen even faster: by right-clicking on an empty spot on the desktop and selecting the Screen settings item from the proposed context menu.

At this point, scroll down the window, until you find the item Advanced screen settings , click on the latter and choose the screen for which to view the refresh rate from the drop-down menu located at the top of the next screen (if connected only one display, this is not necessary). The refresh rate currently in use is specified within the Display Information pane .

To view the maximum frequency supported by the monitor, click instead on the Video card properties item for [X] (where X is the number of the connected monitor), click on the Monitor tab and expand the Refresh rate drop-down menu , in order to view all the refresh rates supported by the monitor for the resolution in use, and possibly set the one you prefer. Once the modification is complete, click on the Apply and OK buttons .

Alternatively, you can get the same information using the management panel of the integrated graphics card in your computer: if, for example, you are using an NVIDIA GPU , open the NVIDIA Control Panel by right-clicking on an empty spot on the desktop and selecting the appropriate context menu item. Then expand the Screen section located in the left sidebar (just click on the [+] symbol next to it) and click on the Change resolution item . This way, you can view all resolutions supported by your monitor, along with their respective refresh rates.

If, on the other hand, you are using an Intel integrated card , locate the Intel HD graphics icon on the Windows taskbar, near the clock (if you do not see it, click on the up arrow to view all the available icons ), right-click on it and choose Graphic Properties from the proposed context menu. Finally, click on the icon dedicated to the screen and use the drop down menu refresh rate to see the refresh rate values that can be used on your monitor.

How to see monitor Hz on Mac

Seeing the Hz of the monitor on a Mac is really easy. To do this, if you have a Mac without an integrated screen (eg Mac Mini / Mac Pro), or if you have connected any other Mac to an external monitor, open System Preferences by clicking on the gear icon placed on the Dock bar , double-click on the icon dedicated to the Monitor and go to the tab of the same name, located at the top of the window that appears on the screen: you can find the refresh rates supported by the screen in use by expanding the drop-down menu Frequency .

Keep in mind that, if yours is a Mac with integrated screen (eg. IMac or MacBook), the refresh rate menu may not be immediately visible; to remedy the problem, after opening the section Monitor the System Preferences , press and hold down the Option and click on the item Resize : if everything went the right way, you should now see the dropdown menu on the frequency .
