DisplayBuddy vs MonitorControl

DisplayBuddy controls supported external monitor settings from a Mac menu bar or Windows taskbar. Depending on the display, it can adjust brightness, contrast, speaker volume, input source, resolution, and rotation. The Mac app uses DDC for hardware control and can use gamma dimming when a monitor does not respond. The maker says it also controls supported LG webOS and Samsung Tizen smart monitors over Wi-Fi. Users can save presets and synchronize brightness across displays. On Mac, presets can be scheduled by sunrise, sunset, time of day, charger state, or connected display; the app also supports Shortcuts, Siri, a command-line interface, and MCP. The Windows app supports Windows 10 and 11, with presets, hotkeys, input switching, and resolution and refresh-rate controls. Personal costs $24.99, paid once for one Mac, Pro costs $29.99, paid once for up to two Macs, and Family costs $49.99, paid once for up to five Macs; each includes lifetime access. There is no free plan, but a 7-day trial is available. Core controls work offline after internet-based license activation.

MonitorControl is a free macOS app for controlling external display brightness, volume, and contrast while showing native macOS on-screen displays. It supports DDC on external monitors, Apple protocols on Apple and built-in displays, gamma-table dimming, and shade control for AirPlay, Sidecar, DisplayLink, and other virtual screens. Brightness can transition smoothly or dim to full black. Standard Apple brightness and media keys work, and custom shortcuts are available. Multiple displays can be synchronized with one slider or shortcuts, including copying brightness changes from built-in or Apple displays to non-Apple screens. Dozens of customization options are provided, with more under “Show advanced settings.” MonitorControl is free, with no trial, and runs on macOS. Version 4.0.0 lists Catalina 10.15 as its baseline; full functionality is available on macOS 11 Big Sur or newer. The latest listed release is v4.4.0.
