GammaDimmer • screen dimming
Dim screen brightness in sync
Only for Mac
Free
Mac
Dim the brightness of all your screens without compromising color accuracy.
Use handy sliders or keyboard shortcuts to keep the luminance of all your displays in sync.
Works with iPad Sidecar, DisplayLink and all external monitors:
• Dell
• LG
• Samsung
• BenQ
• Sceptre
• PRISM
• Xiaomi
• AOC
• Acer
• HP
• ASUS
• ViewSonic
• MSI
• USB Monitors
Notes:
- Gamma Dimmer dims brightness by temporary altering the Gamma formula of the screen (or by placing a dark overlay where Gamma is not available)
- It does NOT use DDC/CI to change the real hardware brightness of your monitors
- The app can't listen for brightness keys because of the App Store sandbox, it instead uses the Fn-F1/F2 keys
- The dimming goes away as soon as the app is quit
For adjusting the hardware brightness, volume or input of the monitor, check out my other "Lunar Pro" app on the official website.
