Custom Refresh Rates through Nvidia Control Panel or CRU/EVGA Utility

Random Guy · 21 Apr 2015 at 11:49

Hi all - I wanted to ask because I have a Hazro H27WC, a few years old now but still marvellous to behold, and I have been toying with the idea of OC'ing it for a while now as I know it has the same internals as the infamous Catleaps of the last few years.

Now my question is quite simple: do I need to faff about with custom tool and utilities for this or can I quite simply just add the resolution/refresh rate using the Nvidia Control Panel? Some discussion on the Net has it that the EVGA Pixel Overclocking utility is simply using NCP's in-built functionality and not doing anything special.

Any advice would be very much appreciated

Thanks InvisiblePrawn! Would you say you noticed a demonstrable difference with the higher refresh? Did you test in-game to verify? Was it clearly visible?

CRU makes the OS (and graphics card, and games) to think that you have a native higher refresh rate monitor (the extra options show up everywhere you can set them without the need to do any custom resolutions). This enables a few extra options in the nvidia control panel, such as forcing v-sync to always work with the higher refresh rate even if the game doesn't natively support high refresh rate v-sync (as some games don't, such as FIFA 15).

Will I need anything more than the Nvidia Control Panel to enable the higher refresh?

Thank you very much for that overview HACO - invaluable help and much appreciated.

Yep I use CRU to take my 60hz 1440p IPS to 96hz. I've gone as high as 110hz but then the colors looks a little washed out (even with correction). Huge difference, I refuse to play at 60hz ever again lol. So simple!

I tried it last night. At 120 it was looking washed out but even worse, leaving pixel trails as I moused around in the Win 7 Desktop. At 90 it fared better - 96 is a good option actually (multiple of 24) and I think I will add this next and see how it goes.

Just to update here - I have been on 96 Hz with my Hazro for a good few weeks now, all going well and can't really complain. Difference to 60 Hz is not as pronounced as I expected but mind you I have not been switching back and forth to try comparisons all that much. Just glad to be running at the higher frequency.
