Make sure you've updated them, and if you're on the latest version you might wanna roll back, use an older version just to see if it works. Make sure you get the drivers from AOC official's website.

Also, I see you're not using HDMI so you might wanna check if your DisplayPort cable supports up to 144hz otherwise you might wanna switch to an HDMI cable.
