Overclocking your monitor is essential for the same purpose as overclocking your processor; to get a little more performance. It involves increasing the refresh rate beyond the stock rating, meaning it can draw more frames on the screen per second. In this article we will be talking about How To Overclock MonitoR.
For most people most of the time it’s not exactly an essential thing to do, but that doesn’t mean it’s not a neat trick or that you shouldn’t do it. Here’s what you need to know.
The number of times per second that an image displayed on a screen needs to be regenerated to prevent flicker when viewed by the human eye.
So simply put, a 60Hz monitor will refresh the image 60 times every second, 75Hz will do it 75 times a second and 144Hz will refresh 144 times per second. Generally speaking, especially in computing and PC gaming, higher is better. The human eye and brain see at around 24fps, but we’re capable perceiving far greater refresh rates than that.
Can any monitor do it?
Potentially. Whether you can increase the refresh rate or not depends on your specific panel. Even in identical monitors, the display panels within them are not all created equal. You may read stories of significant increases for some on your particular monitor, but your own might not be so lucky.
For example, you can use a BenQ RL2455HM and there are many successful reports of folks overclocking from 60Hz to 75Hz. My own monitor can only go up to 70Hz. Read this article to know How To Overclock Monitor.
Update: As pointed out in the comments, take every step to check your panel specs first. Not only are not all panels created equal but some manufacturers may have applied a factory overclock already. In this instance, the risks are much higher if you attempt to push the limits even further.
It’s very much one of those your mileage may vary situations.
It’s actually a very straight forward process. You can either use a third-party tool called CRU, or attempt to use software from AMD, NVIDIA or Intel. All are free, so we’ll look at each.
How To Overclock Monitor CRU – Custom Resolution Utility
This one is one of the older methods, and may not be compatible with all GPUs or integrated Intel graphics. It does, however, seem to work very well with AMD graphics. You can download it here and once installed it’s a straight forward process to change up your refresh rate.
- Open CRU
- You’ll see two boxes, one for detailed resolutions and standard resolutions.
- Under detailed resolutions click add.
- Click on timing and change it to LCD standard.
- Change refresh rate to something above the standard value, a good start is an increment of 5Hz.
- Click OK.
- Reboot your PC.
If you’re using an AMD GPU you can achieve similar results using the AMD Radeon Settings application. Right-click its icon in your taskbar and follow these steps.
- Right-click on the desktop and select AMD Radeon settings.
- Click on the display tab.
- Next to custom resolutions, click create.
- Change the refresh rate to your desired level.
- Click save.
Reboot and use the steps above next to change to your custom refresh rate.
The steps for NVIDIA users are mostly similar as for AMD, with the main difference being NVIDIA’s controls look a bit more utilitarian!
- Right-click on the desktop and select NVIDIA control panel.
- Expand the display menu.
- Click change resolution and then create custom resolution.
With the NVIDIA control panel you can test your created settings before applying. Once you’re happy, reboot and hit the steps above to implement.
Using Intel graphics
Intel’s own graphics control panel will also let you create custom resolutions and refresh rates fairly easily.
- Open Intel HD graphics control panel.
- Select display.
- On the left click on custom resolutions.
- Enter your width, height and desired refresh rate. 5 Click add.
If your display can’t go any higher, you’ll be prompted and will have to either quit or try again. If you get a successful lock-in, reboot and hit the steps above to make sure you’ve got the new one selected.
How To Overclock Monitor, How to verify your overclock
To test and make sure that your new refresh rate is working as it’s supposed to, there’s a great online test that you can run. Visit http://www.testufo.com/#test=frameskipping in your browser and follow the steps on screen. It will recognize the refresh rate you’ve got selected for your monitor at that time.
What you basically do is take a photo of the moving graphic with a lower shutter speed and if everything is working as it should you’ll get a (poor quality) photo like the one above. If the shaded boxes are in a line and unbroken, then you’ve been successful. If the boxes are separated, then you’re getting skipped frames.
Just like overclocking a processor, all of this is done at your own risk. You should be able to experiment without blowing up your PC monitor, but there are never any guarantees . So be careful with your gear. Also bear in mind that the connection to your monitor from the PC could have an effect, as does the resolution. You might be able to overclock at 720p, for example, but not at 1080p.
And as already mentioned none of this is an exact science and your mileage may vary. It’s hard to say we’d recommend this as an essential thing to try, but if you like to tinker there’s nothing stopping you.
How To Overclock Monitor Overclocking Your Monitor: Benefits
Understanding the benefits is 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. 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, increasing your refresh rate to match as close as you can with your frame rate, you can eliminate some of this.
As with any overclocking, just be sure to take things slow. When you overclock your monitor, it can be tempting to go faster but that’s how things break. If you do it correctly, you’ll soon find you can enjoy an even better viewing experience than before. If you’re an old hand at doing this, be sure to drop any tips or tricks into the comments below!
