Customer Support & FAQ

Which keyboard shortcuts control external monitor brightness?

MonitorGlow provides three standard shortcuts out of the box:

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

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.
