If you know a little about technology, you’ve probably heard of overclocking before. But even those who spend their time tinkering with their computers may not know how easy it is to overclock your monitor. This goes beyond the resolution tweak: you can actually increase the refresh rate of your monitor without spending a dime. this won’t work for every monitor, as it depends on your specific panel, whether you can overclock and how much will be completely arbitrary.
Fortunately, figuring out what’s possible with your monitor is simple, and it can be done from within the NVIDIA Control Panel with just a few clicks. Read on to find out what you need to know to see if you can squeeze a few extra hz out of your monitor with the NVIDIA Control Panel!
The NVIDIA Control Panel is only available if you are using an NVIDIA graphics card. If you don’t have it installed, you can get it from the App Store.
How to overclock your monitor
First, open the NVIDIA Control Panel and click “Change resolution” under the Display section on the left side of the window. Make sure the monitor you want to overclock is selected. If you don’t have multiple monitors, don’t worry about this as your only monitor will be selected.
From here, click the “Customize …” button, which will open a new Customization window. Check the box next to “Enable a resolution that is not exposed to the display” and click the “Create Custom Resolution” button, which will open a new Create Custom Resolution window. You will create a “custom resolution” for your monitor that runs at a refresh rate above your monitor’s advertised refresh rate.
From within the Create Custom Resolution window, find the value next to “Refresh rate (Hz):” and click the up arrow next to it to increase the numbers one by one. Click the “Test” button. If your screen goes black, and your monitor complains of not receiving a signal, don’t panic. Wait a few moments and your desktop will appear again. This means your monitor failed the test and was unable to run at higher refresh rates. If your screen doesn’t go black but you come across strange visual artifacts, that’s also a sign you’ve failed the test.
However, even if you fail your first test, all hope is not lost. As far as the tests go, you will get better shots by trying a higher frame rate at a lower resolution. For example, if you happen to have a 144hz 1440p monitor, trying to run at 145hz 1080p might work while 145hz 1440p doesn’t. There are no guarantees, of course. It goes without saying that if you fail the test at one hertz above your refresh rate, you won’t be able to pass the test at a higher refresh rate.
In fact, if you successfully pass the test, close the “Pass test” prompt window and click the “OK” button in the Customize window, which returns you to the “Change Resolution” area in the Control Panel where you started. Now you can select the custom resolution that you have made and press the “Apply” button at the bottom right of the screen. Congratulations! You have overclocked your monitor!
If you don’t know what you are doing, it is best to leave the other fields in the “Create Custom Resolution” window only, such as Scan type, Time, and Color depth. Focus your adjustments on refresh rate and resolution.
