The built-in display brightness of your Macbook or iMac is synchronized to the external monitor. Custom brightness and contrast values are computed for each external monitor by passing the built-in brightness through a curve algorithm that is completely configurable by the user.

If you got a new monitor for your Mac, you noticed there's no way to control its brightness from the Mac.

Lunar brings back brightness control for monitors, along with volume, contrast, input switching and can even turn off monitors or the built-in display.

Hi everyone! I'm Alin, the creator of 🌕 Lunar, an app for controlling every aspect of your 🖥 external monitors. 1 year ago I quit my well paid job and began investing my time into making a living off Lunar. I'm now making half of the salary from that 💸 "well-paid job" solely from Lunar sales. That has allowed me to work on Lunar full time, while also creating other Mac apps on https://lowtechguys.com/ I'm giving 75% OFF ‼️ the Pro license to 20 ProductHunt users. Use the following coupon code at checkout: PH75OFFLUNAR5 --------- I've been posting about major versions of Lunar on ProductHunt since v1, but this one is special. I finally feel that Lunar has reached a very stable base, compatible with all monitors in existence* and able to control things that you didn't even know was possible. Adaptive Brightness for external monitors is Lunar's greatest feat, but there are a few new features you might find useful: • ⏻ BlackOut: - 💻️ Turn off MacBook display without closing the lid (automatically when a monitor is connected) - 🖥️ Turn off external monitors while still keeping their charging/USB functions so you can focus on one screen at a time • 🎬️ App Presets: set brightness to a specific value based on what app is visible • ⏱️ Schedule brightness to change on specific time of day • 🔆 Brightness Dimming for Sidecar, AirPlay, TVs and DisplayLink screens • 🎨 Color Calibration controls (if the monitor supports them) • 🔌 Switch to other HDMI, DisplayPort or Thunderbolt ports using keyboard shortcuts (you can forget about KVM devices) • ＄Command-line scripting: https://lunar.fyi/#cli • 🏮Use any Ambient Light Sensor for adapting brightness: https://lunar.fyi/#sensor * some monitors might appear incompatible because they are non-compliant with the DDC standard or because of Mac hardware limitations, this is not a problem with Lunar and can't be fixed in software

@alin23 thank you! Just bought and excited to try!

Hey, I am using Windows right now but I'm considering to buy new Mac Mini (Studio?) so, will Lunar be helpful? Edit: I do have an LG Monitor but its not a UHD one.

@choudhary Lunar is especially useful on Mac Mini since your only choice for a screen there is an external monitor which doesn't support brightness control from the Mac. The only (modern) monitors that support native Mac brightness control are the LG Ultrafine 5K and the Pro Display XDR which are prohibitively expensive. For everything else, there's Lunar :) If you also get a monitor with speakers or jack output, you can use Lunar to also control its volume. And if you want to keep using your Windows PC with the same monitor, you can use Lunar to switch inputs with a keyboard shortcut. If you want automatic brightness for the Mac Mini, there's also the possibility of using a wireless ambient light sensor: https://lunar.fyi/sensor (although you have to do it yourself ^_^)

@alin23 sounds amazing! (hope the promo doesn't run out until I get my hands on the new Mac Mini/Studio :P)

@choudhary If you get the Mac Mini after the coupon expires, let me know and I'll make an exception ^_^

@alin23 that's so nice of you, thank you! :)

Very nice "side hustle"! Congrats on the launch 🎉

@infr Thank you Kim! ✨

Insanely useful for anyone connecting multiple computers to their displays (although this is just one of the many use cases). A new Mac classic is born.

Great inovative product
