Gamma Dimmer

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

Note: Gamma Dimmer uses Software Dimming using Gamma (or a dark overlay where Gamma is not available).

It does NOT use DDC/CI to change the real hardware brightness of your monitors.

For adjusting the hardware brightness, volume or input of the monitor, check out my other Lunar Pro app on the official website.
