Q: Brightness keys suddenly not working

Hi! I am on a mac mini with wireless keyboard, suddenly my brightness adjusting keys don't work. I have tried two other wireless key boards, those don't work either. All other keys work fine, just not brightness. My display sections in my settings doesn't have an option for brightness, what is going on?

iPod mini, iOS 9.3.1

It is a plug small than a usb, it has a lightning bolt on it. It is plugged in. It is a mac desktop monitor.

Is there a way to just adjust it without the keys?

Did the brightness control with the keyboard keys work before with this monitor?
What specific monitor?
Is there a brightness slider in Display Preferences?
