ASUS DisplayWidget Center vs m1ddc

ASUS DisplayWidget Center is free software for managing and adjusting compatible ASUS monitors on Windows and macOS. It lets users change display modes, brightness, contrast and colour temperature. Productivity tools include eye-care controls, MultiFrame window layouts, PIP/PBP, KVM controls and ZenScreen auto rotation. App Tweaker can apply presets or custom profiles to selected apps, and users can assign keyboard shortcuts to monitor settings. OLED Care includes pixel cleaning, uniform brightness and timer reminders, though feature availability varies by monitor. Gaming tools such as AI Visual and GamePlus are limited to specific monitor models or series. The AI Assistant accepts text or voice input to adjust settings and answer ASUS display product FAQs, but requires internet access and an account login; use may be limited to maintain service quality. Display CLI provides programmatic display control, while AI Agent Skills let compatible agents change settings using natural-language requests. Supported systems are Windows 11 or later and macOS 12 Monterey or later. The software works only with select ASUS monitors.

m1ddc is a free command-line tool for controlling external displays from Apple Silicon Macs. Through DDC/CI, it can set or read luminance, contrast, RGB gain, volume, mute, and input source when a display supports those controls. Supported connections include USB-C, DisplayPort Alt Mode, and compatible built-in HDMI ports. Certain Dell displays also expose PIP, PBP, and KVM configuration. The command-line interface is intended for scripts, and the project links to a Hammerspoon example. A Raycast Display Input Switcher extension is also linked, although it does not cover every m1ddc feature. The tool is available for macOS on Apple Silicon and does not support Intel Macs. Building requires clang from Apple’s Command Line Tools; the README says those tools install automatically if absent. The repository includes an MIT License. Display behavior depends on the connected monitor’s supported controls.
