did they disable this in OS X? Used to work fine for me, but I gave up buying $2,500 iPads after the keyboard debacle and ensuing 1984 treatment

It's available on the TouchBar control, not sure about elsewhere.

On linux: `ddcutil setvcp 0x10 + ` to increase brightness (and - to lower it). Ymmv.

This works with my Caldigit dock and Dell monitors and I love it.

No one else in my house cares though.

I love this thing. It only seems to work over DisplayPort cables for me. HDMI doesn't work. I'm using a MBP mid-2014.

Saved me from buying a new monitor or something silly like getting an iMac. Seriously weird why they don't just support DDD/CI natively.

Great codebase. I stumbled on this while trying to figure out how to programmatically control screen brightness in a macOS app. Turns out that this is far more difficult than imagined. Even controlling just the built-in screen, something I assumed would be included in Apple's libraries, was not included. The source code in MonitorControl is very well written and commented and helped me catch the mistakes I was doing in my very hacky solution.

It does work over USB-C on 2019/2020s
