Hi, I found a program that allows you to overclock your monitor refresh rate a few weeks ago and after weeks of successfully running a 60Hz monitor @ 75Hz I have decided to make a guide on how to do this. 

I heard that Nvidia has this function built into their drivers and I have not tested this on integrated Intel GPU's so I can only promise that this works on AMD Cards

Before we start the guide you will need to download the program, it is called CRU or Custom Resolution Utility.
 

I have uploaded the program to my Google Drive link here - https://docs.google....dit?usp=sharing

Note - After completing this guide the program no longer needs to be run and after checking running processes I found that it is infact not running. However I am unsure if it can be deleted without putting your refresh rate back to stock which is why I kept it in my main C: drive directory. 

 

 

This process will take about 10 minutes, as far as I know it is not dangerous and I have tested it on 4 different monitors without any problems, my 2 main monitors have been running successfully overclocked for many weeks with 0 issues... however if anything goes wrong, I am not responsible :P

 

Step 1 -  Run the program and delete all monitors in the drop down list that don't have "(active)" in their name. When I first started the program I had many duplicates of a single monitor. You should be left with something like this -

(Please note that I am running a dual monitor setup which is why 2 monitors on the list say "(active)". 
 
 

Step 2 -  Click "Add..." below the list of "Detailed Resolutions". A window will open. Change the "Timing" to "Automatic - LCD standard".  In the top 2 boxes enter your monitor's resolution, in my case this is 1680 x 1060. 
This is where we get to increasing the refresh rate. In the bottom box - "Refresh rate:" Enter a Refresh rate that is higher than your stock. In my tests a good first increase is 10Hz which took me to 70Hz from 60Hz.

Step 3 - After adding your first custom refresh rate, repeat the process this time going up in steps of 5Hz. You can have a total of 4 Custom settings which took me up to 80Hz

You now how to restart your computer. Click "OK" to close the program first and then restart. 

Step 4 - After restarting your computer Right Click on your desktop and go to "Screen Resolution"

Step 5 - Now go to "Advanced settings" (select the monitor you are editing first if you have multiple monitors), followed by the "Monitor" tab. Now when you go to the drop down list of available refresh rates you should see all the ones you have added. This is where you find what your monitor is capable of.

Increase the refresh rate step by step hitting apply each time. If the increase is successful, everything on your monitor should look as normal (Except you are now running at a higher refresh rate). Increase the refresh rate until after clicking "Apply" your monitor no longer displays anything on the screen, don't panic when this happens, Windows will automatically Revert back to your previous setting in 15 seconds. What might also happen is the image on your monitor might not look right and everything on your screen might become blurred. In this case also wait 15 seconds until Windows reverts back to the previous refresh rate. 

In my case 75Hz was successful but after applying 80Hz nothing showed up on my monitor until after 15 seconds it went back to 75Hz. This means that 75Hz is the highest my monitor can go.

 

Step 6 - 

Once you find your monitors limit, open up the Custom Resolution Utility again and delete all the Detailed Resolutions you have created except for the highest one that works correctly for you.

You can then click OK and close all the Windows you have opened. As you do so and drag some windows you should notice that everything is smoother because you have now overclocked your monitor :)

I didn't have to do what he described with the 4 monitors I did this on, what I described in the guide seems to work perfectly without any additional steps required.

i had to patch dvi freq in order to get my monitor work at 70hz with single link dvi cable

Oh yeah, that could be a thing, Single link DVI might not be enough.

Meh this int worth it overclocking monitors it stupid because most monitors that are 60hz only run at 60hz or if you can push them to 70 or so the pixel response is bad and you get 100% no benefit but possibly a dead monitor.

Is there even any point in overclocking a 120hz monitor?

Not true, I noticed a HUGE difference even when just dragging Windows around on the desktop it looks MUCH MUCH smoother at 70Hz or 75Hz than it did at 60Hz. The increase is also very noticeable in games. If it wasn't worth doing I wouldn't spend time on it making this guide :P

Also...the pixel response time is the time taken for a pixel to respond as the name suggests so... the higher the frequency the lower the time... ;)

I did this a few months ago when I was looking into downsampling (1440p Image Quality on a 1080p panel - Gaming only)

I used CRU to do what you did, 60hz to 75hz, has been great for vsync and those occasional fps dips are much more manageable.

Great work making a guide for other people.

The problem is most monitors with multiple inputs will frame skip over 70hz..
