ClickMonitorDDC vs MonitorControl

ClickMonitorDDC is a free Windows utility for controlling external monitor settings through DDC/CI. Depending on monitor support, it can adjust brightness, contrast, speaker volume, RGB gains, and color temperature. Multiple displays can be controlled independently or have settings synchronized. Controls include tray options, hotkeys, and the mouse wheel; shortcuts switch profiles, while command-line arguments or hotkeys can automate adjustments and profile changes. The listed Windows versions are 7, 8, 10, and 11, and the monitor must have DDC/CI enabled. Some laptop displays may restrict DDC/CI, and some monitors may not support every setting. The download is a portable app that runs without formal installation. The privacy policy says the software runs locally and does not collect, transmit, or store personal data from the computer, monitor, or hardware configuration. It separately says the website may collect browsing data and use cookies. The utility is described as intended for professionals, gamers, and everyday users who want monitor controls.

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.
