MonitorControl review
A focused, open-source macOS utility for controlling compatible displays.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
MonitorControl is a free, open-source macOS menu-bar application for adjusting brightness, volume and contrast across external and built-in displays. It is aimed at Mac users who want centralized display controls without replacing their existing monitor setup. Compatible external displays can use DDC, while Apple and built-in displays use native Apple protocols. Software dimming through gamma-table control extends brightness adjustment to displays that support shade control, including virtual screens.
Its strongest advantage is breadth across display types and control methods. Menu-bar sliders provide direct access, while standard Apple media keys and custom keyboard shortcuts support keyboard-based control. MonitorControl also offers native macOS on-screen display feedback for brightness and volume. Brightness can synchronize between built-in and Apple displays, including changes driven by ambient light. AirPlay, Sidecar, DisplayLink and other virtual screens are supported through shade control, giving the utility a wider reach than a basic external-monitor brightness controller.
The published feature set stays focused on control rather than monitor-management workflows. It does not provide documented input switching, saved monitor profiles, scheduling or CLI/API access, so users needing repeatable multi-monitor scenes or automation should choose a tool built around those functions instead. For Mac users who primarily need free brightness and volume controls, especially across Apple, compatible DDC and virtual displays, MonitorControl is a practical fit. It is less suitable for users on other operating systems or for setups that depend on monitor input management, profile presets or command-line control.
