Also it looks like that AOC display has both HDMI and DisplayPort inputs.

If the cheap AOC supplied HDMI cable does not work properly, replace it with a short high speed cable.

as such then monitors are not an interface that requires a device driver for the computer, some monitors have software though for controlling special features from the monitor manufacturer

if AOC does not have mac software for that monitor then you just have to settle for what features you get out of the box
