So I have overclocked my monitor by first testing the compatible refresh rates in NVCP until it says "Out of range" then applying the compatible refresh rate via CRU. I have achieved 74Hz(from 60Hz), and the specs of the monitor says it's signal frequency is 56~76Hz in https://www.asus.com/Monitors/VC239H/specifications/. I noticed that at 74Hz the dispay is a bit dimmer(which makes the picture quality look better in "Game Mode" preset IMO) than the default 60Hz. So do I have to worry about anything? Or just continue enjoying the 74Hz? 60-74Hz is so noticeable that I dont ever want to go back to 60Hz. Thank you.
