ASUS DisplayWidget Center vs DisplayBuddy

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.

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.
