If you are tired of the weak performance of your computer monitor or want to increase the quality of the display and speed up its response time, then you should overclock.

Overclocking a monitor is a procedure that involves adjusting its refresh rate above the manufacturer’s specifications. Doing so can achieve smoother visuals, reduce input lag, and improve overall performance. Overclocking can also be risky if not done correctly and may void your monitor warranty.

We will guide you through the steps on how to Overclock a Monitor and maximize its potential without damaging it.

How to Overclock a Monitor

Overclocking a monitor can give you a significant performance boost. It means pushing your monitor to run at a higher refresh rate than its factory settings. This results in smoother and more receptive gameplay and better overall visual performance.

Before you start overclocking your monitor, make sure it can do so. Check the manufacturer’s website or manual for information on the maximum refresh rate that your monitor can handle. Most monitors have a maximum refresh rate of 60Hz, but some newer models can go up to 144Hz or even higher.

What is the Refresh Rate?

Refresh rate includes the number of times a screen refreshes its image every second. Measured in Hertz (Hz), the refresh rate indicates how often the screen can update its image within one second. A higher refresh rate implies that the images on your screen will be more fluid and seamless.

Most modern devices have a standard refresh rate of 60Hz, suitable for everyday activities such as browsing and streaming videos. Higher refresh rates of 120Hz or even 240Hz are becoming increasingly popular among gamers and those who require more precise motion accuracy. 

The benefits of having a higher refresh rate include reduced motion blur, smoother transitions between frames, and improved responsiveness. In addition, some high-end monitors also incorporate technologies like NVIDIA G-Sync and AMD FreeSync to enhance performance by synchronizing the monitor’s refresh rate with the graphics card’s output signal.

Do All Monitors Support Overclocking?

Not all monitors are compatible with overclocking. The ability to overclock depends on several factors, such as the type of panel technology your monitor uses, the quality of the internal components and firmware, and the capabilities of your graphics card.

If you want to overclock your monitor, checking if it supports this feature before purchasing is essential. Monitors with TN (Twisted Nematic) panels tend to have higher refresh rates than those with IPS (In-Plane Switching) or VA (Vertical Alignment) panels but may still not support overclocking. Higher-end gaming monitors are more likely to support overclocking due to their superior components and firmware.

Steps for Overclocking a Monitor

Overclocking a monitor may seem daunting, but it can be a simple and rewarding process with the proper steps and precautions. Overclocking pushes your monitor past its factory-set refresh rate to achieve higher frame rates and smoother visuals.

Before diving into the steps for overclocking your monitor, it’s important to note that not all monitors can overclock, so research your specific model beforehand.

Downloading the CRU Software

If you are interested in overclocking your monitor, the Custom Resolution Utility (CRU) software is an essential tool you need to download. The CRU software is a free tool that enables you to increase the refresh rate of your monitor.

Install & Launch the CRU Software

There are a couple of steps in installing the CRU software:

  • Download it from the official website.
  • Unzip or extract the files into a designated folder on your computer.
  • Run the CRU program as a system administrator by right-clicking on it and opting for “run as administrator.” 

This will ensure that all changes made using this program are applied successfully without any errors. Once you have established the program, you will be presented with a list of resolutions supported by your graphics card.

Doing the Actual Process

Once you have installed the CRU app, run it as an administrator. This will guarantee you have full access to all its features and tools. From there, go to the Add button and start exploring your options. You’ll find various settings and configurations that you can customize to get the most out of your monitor.

Checking Final Results

One common issue when overclocking a monitor is the screen turning black and returning. If you encounter this issue, don’t panic. This means that the current refresh rate value is unsuitable for your monitor. Register another refresh rate value that will work better for your device. 

You can do this by running a benchmark test on your computer and comparing it with previous scores. And with that, Enable FreeSync on a Monitor. If there is a performance improvement, then it means that the overclocking was successful.


Overclocking your monitor can provide a noticeable boost in performance for gamers and other power users. It’s essential to approach the process cautiously and ensure adequate cooling to prevent potential damage. 

Following our guide “How to Overclock a Monitor,” you can safely push your monitor beyond its default refresh rate and enjoy a smoother, more responsive display.


What is the top method to overclock a monitor?

Adjust the monitor’s settings on the computer. Use an overclocking utility that comes with the monitor. You can also overclock the graphics card on the computer.

How do I know if I’m overclocking my monitor?

Some elements you may want to consider include how your computer handles overclocking, whether or not the monitor supports overclocking, and what type of graphics card you use. If you are still determining whether or not you are overclocking your monitor, it is generally a good idea to fall on the side of caution and reduce the frequency of your graphics card.

How to Overclock a Monitor on a Mac?

The System Preferences window and select “Display.” In the “General” tab, You’ll observe an option to “Update All.” Clicking this will allow the OS to overclock all of your devices. Another way to overclock your monitor is using a third-party app like Overclocking Monitor. This app allows you to manually set the clock speed for your graphics card and monitor.
