Overclock monitor

As you might already know, you can overclock a lot of hardware easily for a higher performance. That applies for computer hardware too, 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 pretty awesome and is something that very many people actually do. If you have a quality panel, you can push the refresh rate of your gaming monitor or everyday use monitor beyond the specifications for a more fluid experience.

Overclocking your monitor takes very little effort and the software that you are going to need is absolutely free for both AMD and NVIDIA users. In this article, we’ll show you exactly how to overclock a monitor.

If you have an AMD graphics card, you can use CRU (Custom Resolution Utility), which is very popular. With the software, you can easily increase the frequency (Hz) with the automatic modes in it. If you are more experienced, then you can enjoy additional features that this program offers, such as creating custom display modes. You can very easily become an expert in this field, as the monitor hacking community are very help. The author of the software, ToastyX, also created the Strobelight utility, which allows you to use Lightboost in 2D mode without any hassles.

NVIDIA users can use CRU too, but have some more options as well. Custom refresh rate adjustment is built in the GeForce driver, so you can overclock your monitor just by opening the NVIDIA Control Panel, click on “Change Resolution” under Display Tasks followed by “Customize”. That 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. When this limit is reached, back down a few ticks and save it there. Now open and play 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 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 monitor. We also recommend using TestUFO for testing too.

As an NVIDIA user, you can also use the Precision X16 utility, which is a very simple program that you can use to adjust the refresh rate of your monitor via the slider. You can also get this tool on Steam if you are not bothered to register.

One thing to keep in mind is that cables do in fact matter. Use either a DisplayPort or dual-link DVI connector when possible, as these type of connectors allow more bandwidth than current HDMI standards. Also try to keep the cable length short to prevent signal degradation. Avoid adapters whenever possible.

The last thing we want to say is that be cautious about overclocking any hardware. It will probably void your warranty so be prepare to accept the consequences if things go sour. I have yet to hear about anyone destroying their monitor by overclocking it, but that doesn’t mean that it can not happen, so overclock at your own risk.

    I’m using 1920×1080.

    How do I know what version I am using? And does it depend on only the cable or the connectors on the graphics card and monitor as well?
