Have you ever wondered how to check your monitor refresh rate and change the refresh rate of your monitor?

The refresh rate determines the details of an image. Whether you are a Windows or a Mac user if you use a monitor and want to check and change the refresh rate you can do so very easily.

During gaming, we prefer going for a higher refresh rate to get the best experience and eliminate screen tearing. At other times, a medium to low refresh rate also works fine for most of our tasks.

In this post, I have covered ways you can do whether you have a Windows 7/8/10/11 or a Mac OS system. I have given a comprehensive guide here.

Let’s get started!

What is Refresh Rate in a monitor?

Refresh rate is a measurement of how many times a monitor will redraw the entire image on the screen within a second. Refresh rate is commonly measured in hertz (Hz).

The higher the refresh rate is, the less likely it is that you will see any tearing or stuttering that may occur.

If you are gaming, watching movies, or doing any type of work that involves videos, you may want to consider upgrading your refresh rate to at least 60Hz or more.

In most cases, gamers will want a monitor with a refresh rate above 120Hz.

However, for a normal computer monitor, a refresh rate of 60-75Hz is going to be fine, as long as it has a response time of under a millisecond.

How to Make your monitor Run at 120Hz or 144 Hz?

You may have seen the advertised refresh rate of 120 Hz or 144 Hz while purchasing your monitor, but you may have a limitation when trying to change the refresh rate in Windows.

It can be due to the following things:

1. Changing the Old HDMI cable

Your HDMI cable is old, and now it does not support transmission and a good quality HDMI cable. In that case, you need to change your cable, which would help you increase your monitor refresh rate.

2. Upgrading Low-Quality Graphics Card

The Refresh Rate may not support your older graphics card, and you have got a monitor upgrade.

In that case, you need to check how much your GPU can render FPS and if it goes with your monitor’s higher refresh rate.

3. Updating the Graphics Driver

We need to get our graphics card to send frames at a higher rate. If you have a newer card, this is probably already set up.

But if you have an older card or integrated graphics, you’ll have to update the drivers or BIOS to enable higher refresh rates.

Is it safe to overclock the 60Hz monitor to 75Hz?

Yes, it is safe to overclock a monitor. When you overclock a monitor, your monitor will display more frames per second, making the image smoother.

If you overclock your monitor to 75Hz, you need to make sure your monitor supports 75Hz so that it will work.

If your monitor does not support 75Hz overclock, your monitor will not work.

In case your monitor does not support 75Hz, it will revert to the default 60Hz refresh rate. So, you can try out to overclock your monitor.
