Hi Product Hunt! 👋 I'm Petr, the maker of Lumadio.
I work on a MacBook with an external monitor, and two things annoyed me every day. macOS can't dim an external display from the keyboard the way it dims the built-in one. And there's no way to turn down one app: if Slack pings during a call, it's everything or nothing.
The fix used to be two separate paid apps that don't talk to each other. So I built one menu bar app that does both:
🖥 Dim each external display on its own, change resolution and refresh rate, or mirror for a presentation
🔊 Set volume, mute, or solo any single app, with live audio levels
🎬 Save display + audio together as scenes (Movie, Work, Meeting...) and switch in one click
⚡ Pro adds XDR brightness, Face Light for video calls, per-app output routing, and automation like lowering music when a meeting starts
Pricing is simple: free download, and the basics stay free. Pro is a one-time $4.99, no subscription, and you can try it free for 7 days.
One honest note: the App Store version dims through software, so it darkens the image but doesn't change your monitor's backlight.
It runs on Apple Silicon Macs with macOS 14.2 or later. I'd love to hear what you would add next, and which monitor you use. I read every comment today!
