ASUS DisplayWidget Center vs Twinkle Tray

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.

Twinkle Tray is a Windows utility for managing brightness on multiple monitors from a system-tray icon. Sliders can adjust one display or all displays at once, and the app can control DDC/CI monitor features such as contrast, volume, and power state. It supports most laptops and DDC/CI-enabled monitors, using WMI for internal laptop displays and DDC/CI for external displays. Users can schedule brightness adjustments by time of day or when the computer is idle, and bind hotkeys to particular displays or all of them. Command-line arguments support custom scripting, and the application is localized in over 20 languages. Twinkle Tray is free and can be obtained through the Microsoft Store or as a GitHub installer. Compatibility may be limited with VGA or DVI connections and some USB, Thunderbolt, or Surface docks using HDMI or DisplayPort. Its privacy policy describes collection of settings, operating system, CPU name, app version, user interactions, and estimated location through Google Analytics; users can opt out in Settings.
