How To Overclock Your Monitor

You may already know you can improve your computer's performance by overclocking your processor or graphics card but did you know you can also overclock your monitor?

Overclocking your monitor increases your refresh rate which can ultimately improve the smoothness of your overall experience. Overclocking a monitor is actually really simple to do and in this article, we will cover the benefits and risks that come with it, and how to do it.


Before we get started with how to overclock it’s best to understand the limitations our equipment can have and any unwanted risks that can come with overclocking. Before overclocking anything it is best to check your warranty to see if doing this will void your warranty as in some cases it will. Overclocking won't cause too much harm to your monitor but if it isn't covered then be aware you are continuing at your own risk.

Overclocking the refresh rate on your monitor would rarely damage the internal hardware but the capabilities of each monitor are different. High-end gaming monitors sometimes come with the option to overclock so be on the lookout for one of these when you consider a newer monitor if overclocking is something you wish to persist with.

The main risk with overclocking is reducing the lifespan of the monitor itself. It should only reduce the lifespan a short amount but basically, an increase in the monitors refresh rate requires a faster current which will increase the energy output. This increase in energy will drain more power from your power supply and can create more heat internally which can, of course, wear down components over time.


Understanding the benefits is really just understanding what a refresh rate is. Your monitors refresh rate is how many times per second the image is refreshed and often 60Hz is enough. But with higher powered graphics cards comes higher frame rates and when your frame rate on your GPU is out of sync with your refresh rate (60Hz +120 FPS) you can get a screen tear resulting in a jittery experience. So naturally increasing your refresh rate to match as close as you can with your frame rate you can eliminate some of this.

Overclocking using Nvidia

Overclocking is similar no matter which graphics card you have in your setup but we will outline both below.

how to overclock your monitor step 1

As mentioned its relatively easy to overclock your monitor. First, you want to navigate to your Nvidia control panel (right click on your desktop). Once open you should be in the change resolutions page. From this page scroll down and select the ‘Customise’ box underneath ‘resolution’.

Next, you want to ‘enable resolutions not exposed by the display’ and click ‘create custom resolution’.

From here it is best to keep the settings the same and only change the ‘Refresh Rate’. Start by increasing the amount by 5 Hz at a time and know that most monitors unless they explicitly say otherwise can go up around 15Hz max. It’s worth noting in some cases this can be higher depending on your GPU, connection type (HDMI/DisplayPort), and monitors capabilities.

Overclocking using AMD

If you are using an AMD card first you need to go to your Radeon settings and click on ‘Create’ which can be found next to ‘Custom Resolutions’. It doesn't matter if you have AMD or Nvidia setup you should still only increase your refresh rate in increments of 5Hz. Increase it until the signal is lost and the screen reverts back to a refresh rate it can use then you can go up in increments of 1Hz to maximise the refresh rate.
