AOC monitor blinking

[gongz6]

Hello everyone, I recently bought an AOC G2260VWQ6 21.5" LED 75Hz FreeSync. I installed the drivers and selected 1920x1080 at 75hz. Although, when starting CSGO and LoL the monitor starts blinking sometimes. I've changed to 60hz and now it doesnt blink anymore. Can I get any help?

Thanks
