I bought this monitor a couple months ago not knowing of its great overclocking potential. I have a Radeon RX 480, and have tried to overclock it via CRU, but I'm running into a problem. It says there's a higher refresh rate on the profile, but when I run a test via https://www.testufo.com/refreshrate it says 60 Hz, and in Windows it shows as 60 Hz with no possibility to change it. I'm fairly new to monitor overclocking, so any help would be appreciated! Thanks!
