ASUS DisplayWidget Center vs Monitor Switch

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.

Monitor Switch is an MIT-licensed service for switching a monitor’s input and controlling its DDC/CI features through a browser interface, HTTP API, scripts, or Home Assistant. It is designed for people who use one monitor with multiple computers, including when the computer currently displayed is asleep or off. Where a monitor exposes the controls, the service can adjust brightness, contrast, volume, mute, picture mode, colour temperature, RGB gain, and black level. It can also read usage hours, firmware level, refresh rates, and power state. Editable profiles set monitor values and can replace incorrect capability detection. For Home Assistant, MQTT discovery presents profile features as entities such as selectors, sliders, and sensors. The service runs on a Raspberry Pi connected to the monitor by HDMI; setup requires Raspberry Pi OS and SSH, and installation uses an Ansible playbook. The project is described as usable but not yet released. Hardware verification is reported only for a Samsung Odyssey G9 with a Raspberry Pi Zero 2 W; other monitors have not been verified.
