Screen Dimmer & Display Key
Only for Mac
Free · In‑App Purchases
Mac
Dim external displays with keyboard shortcuts and quick presets. Try every feature for 3 days, then keep your setup with one Lifetime Pro purchase.
Dim your external display from the Mac menu bar and keyboard. MonitorGlow uses software dimming through macOS gamma controls or a click-through shade. It does not change a monitor's physical backlight.
Try every control for 3 days. After the trial, display controls pause until you unlock Lifetime Pro with one purchase. The purchase screen appears when you try a locked control.
Use keyboard shortcuts, quick brightness presets, a floating level indicator, sub-zero night dimming, and multi-display sync. Your display preferences stay on your Mac. Firebase Analytics collects app usage events automatically to help improve MonitorGlow. Screen content is not collected.
