Is it possible to turn down the brightness of an external monitor via controls on mu Mac? When using my old Thunderbolt monitor I loved that I could turn down the brightness from my Mac keyboard, but on the 2 new monitors I've bought recently, I can only turn down the brightness using their clunky on-monitor system.
Are there any 3rd party monitors that:

Ideally can turn down the brightness via software controls on the Mac or
Have Very easy to use and accessible brightness buttons on them?
You could use the free app MonitorControl to change the brightness on an external monitor with the brightness keys.
