This works great in my setup:
MBP 15-Inch, 2018,
macOS Catalina 10.15.5,
Installed via Homebrew Cask,
LG 34" 5k2k 34WK95U-W via Thunderbolt 3,
Sonnet Echo 11 Thunderbolt 3 Dock,
Dell U3417W 34" via HDMI via Echo 11 Dock.
Volume and brightness work on both displays. Contrast only works on the Dell (after enabling in the preferences) - no big deal. I can adjust brightness on both displays at the same time via the keyboard... that is spectacular. Volume controls work as expected - finally!! Fantastic!!

#82Sometimes I just wonder why does apple don't provide such a basic features/necessities.
Who needs basic features when you have marketing to convince everyone you’re already perfect in every way?

Would you expect Gatekeeper on High Sierra to just refuse to run a current build outright, without even the usual bypass options? I'm not sure if my IT department has been continuing the war against its own users, or maybe I've just put off updating too long.
Lunar is signed and notarized with a paid developer certificate so I don’t think gatekeeper could block it in anyway. It’s possible that in High Sierra you are missing the Swift 5 runtime. You can find details about this in the troubleshooting section of the GitHub readme. Here is the link where you can download an installer for that: https://support.apple.com/kb/DL1998?locale=en_US
That did the trick, thanks! Weird that the error details would talk about code signing when the problem was a missing runtime, but go figure.
I've switched over to using Lunar as of this morning, following the runtime install. Unfortunately, it looks like today's going to be cloudy straight through, so I don't know that I'll get the best opportunity to see the app strut its stuff right away. That said, the UX has been very solid thus far, and I like the extensive configurability even if I have no intention of using more than about 5% of it.
Strong recommend, and definitely worth a coffee!

If you have a touch bar it does, in my experience. Tap the brightness button to open up controls for each monitor.
I don't have a touchbar mac to test, but does it work with external non-apple displays? Via Karabiner you can configure keys to change the external display brightness. Works great on a Thunderbolt Display. Completely ignores my Dell / LG. The main reason why I think this wouldn't work is because in the display properties there's no brightness slider for non Apple external displays. There is one for Apple displays.
Yep, works with my external non-Apple display, LG.

Brilliant app that does the same for windows 10.
Re: MonitorControl: Control external monitor brightness and volume on your Mac
#86Wow, I didn't know this was even possible. It says the controls operate via DDC [1]. How do you know if your monitor, television, or project supports this? And does it depend on the connector used? (HDMI, DisplayPort, VGA?) Does this work for most display peripherals, only newest/expensive ones, or something in between?

Works with my Samsung 4K TV. I also use a display port to hdmi adapter to enable 4k @ 60 hz on the TV.
Re: MonitorControl: Control external monitor brightness and volume on your Mac
#87Might be useful to some: LG Ultrafine 4k/5k brightness can be controlled with the touch bar. Press the Brightness icon on the touch bar and two sliders show up, one for your mac and one for the LG.
Re: MonitorControl: Control external monitor brightness and volume on your Mac
#88I have often wondered if you could exploit a monitor over the DDC bus sending i2c commands. There have just got to be memory corruption bugs in the display controller code. They probably also typically have some flash memory, so perhaps one could permanently reprogram a monitor after the exploit?
Yes. Dell U2414 (afair) could be updated via DDC and the firmware could draw over the input image.

#89There also is https://github.com/Bensge/NativeDisplayBrightness/ (I use it on macOS 10.11 with an external Dell P2415Q, with Fn+F1 and Fn+F2)
