yes . When the display has not this feature OSX can't control anythingDo all the displays connected need to support DDC/CI for this to work?
Download the attached application and execute it. Go to the keyboards tab and then press the brightness up and down keys. "Key Up" and "Key Down" events should appear in the app. Please take a screenshot of it and post it here, thanks.

I can't get this to work. Nothing happens when I click the buttons to increase/decrease the brightness.
Do all the displays connected need to support DDC/CI for this to work?
Hello, cool idea bensge, after a quick test the latest release works well on my Dell P2415Q. Would like to use this app also with an Apple keyboard. So here are the key codes, hope it helps.

Thank you! Well, turns out, it's exactly the same output as I get from a non-Apple keyboard . Can you try Fn+F1/Fn+F2 and see if that works?
Thanks, I got it workingI only have one monitor right now, but I have heard from a user that it works with multiple monitors too (only some support DDC/CI). Also, you should at least see the brightness HUD, even if your monitor doesn't support DDC/CI. Do you use an Apple keyboard? Try Fn+F1 / Fn+F2 or use the tool linked on page 2 to swap your key function from system brightness feature to F1/F2.
