I have it set on 4ms and do not turn off the blur reduction while not gaming. My other settings are 25 brightness, 40 contrast, 5 Gamma, AMA high and using the BenQ XL2720Z ICC profile from http://www.tftcentral.co.uk/articles/icc_profiles.htm#b
It's the closest I could get to my Dell U2311H which has IPS. Also I don't have to switch profiles all the time with these settings which I find annoying. For games that ingore the ICC profile I use the Display Profile software found on the bottom of this article: https://pcmonitors.info/articles/using- ... n-windows/
