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

#22did 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

#23Great 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…
Doing anything on macOS is more difficult than I imagine it to be. For example, writing an alt-tab-type app, enumerating the list of apps and their windows. Good luck.

#25This little menubar control looks like just what I wanted.
Edit: Yes it works great! On my LG24UD58. Perfect! Unfortunately it doesn't seem to work with my Eizo L568 but that's ancient. And I think it had some special USB-based control method. But really glad to be able to get rid of the LG software now.
PS: You have to enable the contrast with a tickbox, otherwise that slider is not shown.

#26If you have Swift experience please check the issues of the repo. Need assistance with the identical monitors issue, it’s there for two years already.

#27I didn't even know it was a thing and thought there was a special chip in the Apple screens to be able to control your screen from your computer.

#28They probably also typically have some flash memory, so perhaps one could permanently reprogram a monitor after the exploit?

#29This might not work with all monitors.

I really would love something like rofi for macos
