As answered by people managing Eloquent JavaScript and Display Dimmer.
Display Dimmer's answer:
Display Dimmer is built for real Windows multi-monitor setups, not just simple single-screen brightness changes. It supports per-monitor brightness and contrast, All Displays control, schedules, app rules, global hotkeys, linked display groups, and DDC/CI hardware control where supported.
When hardware brightness control is unavailable or unreliable, Display Dimmer can fall back to software dimming, making it useful across more monitor, dock, HDR, and reconnect scenarios.
Display Dimmer's answer:
Display Dimmer is designed for users who want reliable monitor brightness control without constantly opening monitor menus or changing settings manually.
It combines quick brightness sliders, DDC/CI support, gamma fallback, automation, hotkeys, app rules, schedules, and multi-monitor controls in one Windows app. It is especially useful for people with external monitors, docks, multiple displays, or setups where hardware brightness control is inconsistent.
Display Dimmer's answer:
Display Dimmer is for Windows users with external monitors who want faster, easier brightness and contrast control.
The primary audience includes people with multi-monitor desks, developers, designers, remote workers, students, gamers, and anyone who changes screen brightness throughout the day or wants monitor brightness to adjust automatically based on time, app, or workflow.
Display Dimmer's answer:
Display Dimmer was created to make external monitor brightness control on Windows easier and more reliable.
Many Windows setups do not provide a simple built-in brightness slider for external monitors, and hardware monitor controls can be slow, inconsistent, or hidden behind physical buttons. Display Dimmer was built to solve that problem with a cleaner app experience, practical automation, and fallback behavior for real-world monitor setups.
Display Dimmer's answer:
Display Dimmer is built as a native Windows desktop app using C#, WPF, and .NET Framework.
It uses Windows display APIs, DDC/CI monitor control where supported, gamma ramp/software dimming fallback, global hotkey handling, and local app settings to manage brightness, contrast, schedules, app rules, and multi-monitor behavior.

Seconded. I won't recommend it and no one I know has recommended it for a decade. It's hard for someone who doesn't know JS to know which parts has changed and is no longer the way to do things. https://github.com/getify/You-Dont-Know-JS... - Source: Hacker News / about 2 years ago
