## 项目历史与用法

ddcctl is a macOS command-line utility for sending DDC monitor control commands, mainly brightness and contrast, to external displays. The README describes it as a personal GPLv3 utility in maintenance mode rather than a broad support forum.

### 项目历史

The GitHub repository was created in August 2014. Its README says ddcctl.m sprang from a TonyMac-x86 forum thread and that DDC.c originated from jontaylor/DDC-CI-Tools-for-OS-X before being reworked by others.

### 采用历史

ddcctl found a durable packaging niche because macOS users with external monitors often wanted scriptable brightness and input control. The README documents Homebrew installation first, followed by release binaries and building from source.

### 使用方式

Users run ddcctl from the shell to adjust display controls such as brightness, contrast, input source, volume, RGB values, and presets when the monitor firmware supports them. The README also points to an example script for controlling two monitors from a Mac mini.

### 为什么软件包爱好者会关心

For package nerds, ddcctl is the kind of hardware-adjacent CLI that earns a formula because it bridges a small OS capability gap. It is tiny, platform-specific, and useful precisely because it makes display controls scriptable.
