How To Overclock Your Monitor

Did you know that it's possible to overclock your monitor very easily? Here's a simple guide on how to overclock your monitor and why you want to do it.


Open up your NVIDIA or AMD drivers settings and find the option to create a custom resolution. Start by increasing the refresh rate until you notice side effects, such as frame skipping.

Then, decrease the refresh rate by 1Hz until you find the sweet spot with stable performance.

As you might already know, you can overclock a lot of hardware for higher performance. That applies to computer hardware as well, as you can overclock your graphics card, RAM and CPU.

A lot of people already know this, but what fewer people know is that you can also overclock your monitor and get a higher refresh rate!

Overclocking your hardware is rather simple and is something that many people do.

If you have a quality panel, you can push the refresh rate of your monitor beyond the specifications for a more fluid gaming experience.

Overclocking your monitor takes very little effort and can be easily done by tweaking the driver settings for both AMD and NVIDIA users.

In this article, we’ll show you exactly how to overclock a monitor.

When Should You Overclock Your Monitor?

If you have a 60Hz monitor and you are getting over 60FPS (Frames Per Second) in your video games, you will only be seeing up to 60 whole frames, because that’s the maximum your monitor can display.

You can overclock your monitor by a few Hz, depending on the quality of the panel, which will allow you to enjoy a higher framerate.

Overclocking For AMD Users

If you have an AMD graphics card, open up your Radeon settings, and under the ‘Display’ section, click on ‘Create’ next to ‘Custom Resolutions’. In the ‘Refresh Rate (Hz)’ field, type in the preferred refresh rate.

We recommend overclocking by 5Hz until you either notice side effects or the screen goes blank for several seconds and reverts to its original settings. After that, you can decrease from that point by 1Hz until you find the optimal refresh rate.

Alternatively, you can use CRU (Custom Resolution Utility), which is very popular for increasing the FreeSync dynamic range. With this software, you can also easily increase the frequency (Hz) with the automatic modes in it.

If you are more experienced, then you can enjoy additional features this program offers, such as creating custom display modes.

Overclocking For NVIDIA Users

For NVIDIA users, the custom refresh rate adjustment is built into the GeForce driver, so you can overclock your monitor just by opening the NVIDIA Control Panel; click on ‘Change Resolution’ under ‘Display Tasks’ and then click ‘Customize.’

This will show a list of all the currently available screen modes. From here, you click on ‘Create Custom Resolutions’ and increase the Hz until you get synchronization errors.

Testing & Other Tools

Run some games that you play, move some windows around, and watch some videos while you keep a close eye on blinking horizontal lines, skipped frames, or other weird behavior.

If you experience one or more of those, simply lower the refresh rate by a few ticks and try again. It’s a trial and error process, as even the same model of a monitor can be overclocked to different refresh rates.

It’s all about finding the sweet spot for your particular unit.

We also highly recommend using online tools for testing.

As an NVIDIA user, you can use the Precision X16 utility, which is a straightforward program you can use to alter the refresh rate of your monitor via the slider.

One thing to keep in mind is that the cable quality matters too. Make sure that the cable and the connector versions have enough bandwidth for the resolution/refresh rate you’re aiming for.

Also, try to keep the cable length short to prevent signal degradation. Avoid adapters whenever possible.

Lastly, be careful about overclocking any hardware. It will most likely void your warranty, so be prepared to accept the consequences if things go south.

There is a very small chance of permanently ruining your display, but that doesn’t mean that it can not happen, so overclock at your own risk.

We also only recommend overclocking your monitor if you have a low refresh rate display.

Going from 60Hz to 75Hz or from 75Hz to 90Hz provides you with a noticeable boost in motion clarity. However, going from 144Hz to around 160Hz will have barely visible benefits and may not be worth the risk and potential stability issues.
