What are the pros and cons of overclocking your monitor refresh rate?

由人工智能和领英社区提供技术支持

Overclocking your monitor refresh rate means increasing the number of times per second that your monitor updates the image on the screen. This can improve your gaming experience, reduce screen tearing, and make your PC feel more responsive. But it also comes with some risks and drawbacks that you should be aware of before you try it. In this article, we'll explain what overclocking your monitor refresh rate does, how to do it, and what are the pros and cons of this technique.

1 What is monitor refresh rate?

Monitor refresh rate is the measure of how often your monitor displays a new frame of image. It is usually expressed in hertz (Hz), which means cycles per second. For example, a 60Hz monitor refreshes the image 60 times per second, while a 144Hz monitor refreshes it 144 times per second. The higher the refresh rate, the smoother and more fluid the motion on the screen looks.

Refresh rate does contribute to more fluid and clear motion, but is not the only factor involved. The most common example is how framerate and refresh rate interact with each other, both having a perceptible influence on motion clarity. Strictly speaking, refresh rate only describes how often the image on screen is updated, regardless of other factors.

2 How to overclock your monitor refresh rate?

Overclocking your monitor refresh rate means forcing it to run at a higher frequency than its default or maximum rated value. This can be done by using software tools, such as Custom Resolution Utility (CRU) or NVIDIA Control Panel, that allow you to create and apply custom resolutions and refresh rates for your monitor. You can also use your monitor's built-in settings or buttons to adjust the refresh rate, if available. However, not all monitors support overclocking, and some may have a limit on how much you can overclock them.

3 What are the benefits of overclocking your monitor refresh rate?

Overclocking your monitor refresh rate can have several benefits, particularly for gamers and content creators. Improved gaming performance, reduced screen tearing, and enhanced visual quality are just some of the advantages. You can reduce input lag and increase frames per second, which makes your games look smoother and more realistic. Additionally, a higher refresh rate can reduce screen tearing by minimizing the difference between the GPU and the monitor output. Furthermore, it can also improve the clarity, sharpness, and color accuracy of your monitor, making images and videos look more vivid and detailed. All of these benefits make overclocking your monitor refresh rate a great choice for content creation, editing, or viewing.

Increasing refresh rate does not improve colour accuracy, measured in Delta E. You can argue for increased vividness and detail depending on how you define these, but there is no spatial improvement in these descriptions, only in the time dimension is anything being affected. You may still perceive this as increased detail during motion, but its more like its better preserving the existing details during motion.

I have noticed that a higher refresh rate resulted in smoother on-screen motion, especially in fast-paced video games or when watching high-definition videos. By increasing the number of times the display updates per second, I have noticed reduced motion blur and improved clarity during fast-moving scenes.

4 What are the drawbacks of overclocking your monitor refresh rate?

Overclocking your monitor refresh rate can come with risks and drawbacks. For example, it can put extra stress on the components of your monitor, such as the backlight, the controller, or the panel, which may lead to overheating, flickering, or even permanent damage. Additionally, a higher refresh rate means higher power consumption and you may need a more powerful power supply unit (PSU) or a better cooling system to handle the increased load on your PC. Furthermore, not all games or applications support higher refresh rates and this can cause compatibility issues like stuttering, crashing, or black screens. Therefore, you should always check your monitor's specifications and warranty before overclocking it and consider potential environmental impacts. Additionally, you may need to adjust your settings or use third-party software to fix any compatibility issues.

Keep in mind video content will need to be played back at exactly, or at a multiple of its framerate to avoid judder. A monitor overclocked to 75hz wont play the video smoothly, dropping many frames to keep sync, so make sure your monitor is switch to a more tv/movie friendly refresh rate when watching video.
