Customer Support & FAQ

Which keyboard shortcuts control external monitor brightness?

MonitorGlow provides standard shortcuts out of the box:

• ⌘ ⌥ ↑ / ⌘ ⌥ ↓ (Command + Option + Arrow Up to increase, Arrow Down to decrease)
• ⌥ F1 / ⌥ F2 (Option + F1 to decrease, Option + F2 to increase)
• ⌃ F1 / ⌃ F2 (Control + F1 / F2)

Why does MonitorGlow ask for Accessibility permissions?

macOS requires Accessibility permission so MonitorGlow can intercept your global brightness shortcuts (⌘⌥↑ / ⌘⌥↓ and ⌥F1 / ⌥F2) while you are actively working in other applications. MonitorGlow strictly listens for designated brightness hotkeys and never logs, reads, or transmits your private keystrokes or data.

What is the trial period and pricing model?

MonitorGlow includes a full 3-day free trial giving you unrestricted access to all display controls, keyboard shortcuts, and HUD bezels. After the trial, you can unlock Lifetime Pro with a single one-time purchase (no subscriptions!) that includes Apple Family Sharing for up to 5 family members.

Does MonitorGlow work with Dell, LG, and Samsung monitors on Mac mini?

Yes! MonitorGlow was specifically engineered for Mac mini, Mac Studio, and MacBook users who connect external displays over HDMI, DisplayPort, USB-C, or Thunderbolt docks.

What is Sub-Zero Optical Night Mode?

Most computer monitors cannot physically dim lower than 20–30 nits, which is still blinding in dark rooms. Sub-Zero mode applies an intelligent optical shade directly to the display output, allowing you to comfortably dim all the way down to 1% without any hardware flicker.

How do I restore my Lifetime Pro purchase?

Click the PRO button in the menu bar popover, then click Restore Purchases at the bottom of the paywall dialog. Since purchases are tied to your Apple ID, your license will restore instantly.
