FluentControl 是一款面向 Windows 的 DDC/CI 显示器亮度与多屏控制工具，同时提供系统音量、输入和鼠标调节。把分散在显示器实体按键、系统声音设置和鼠标设置中的常用操作，放进统一的 Fluent 风格界面。
从办公切换到游戏、从白天切换到夜间，保存一套配置后就能再次调用。多台显示器可以一起调，也可以分别调；常用控制还能留在桌面上，减少反复打开窗口和寻找菜单的操作。
| 你遇到的情况 | FluentControl 的做法 |
|---|---|
| 多块屏幕亮度不同，逐台按按钮很麻烦 | 整体或单独调节，并为每屏设置亮度映射 |
| 办公、游戏、夜间需要重复调整设备 | 保存显示器、声音、麦克风和鼠标的总配置，随时切换 |
| 好用的显示器参数难以整理、迁移和复用 | 按型号管理预设，支持批量导入、导出与兼容性检查 |
| 常用控制分散在多个系统窗口 | 用主面板、托盘、快捷键和半透明桌面面板快速操作 |
- 显示器控制：在硬件支持时调节亮度、对比度、色温预设、RGB、Gamma、饱和度、显示模式、输入源和屏幕音量等。
- 系统色温与 HDR：每屏独立调整 SDR 画面冷暖、恢复原颜色，并按 Windows 能力切换 HDR；HDR 下明确提示亮度、对比度等可能受限。
- 跨型号多屏联动：不同型号也能整体调节；只向支持对应功能和选项的屏幕发送设置，并标明部分支持的情况。
- 总配置与型号预设：总配置保存整套设备状态，型号预设保存可复用的单屏参数。更新时保留离线设备参数，修改库中预设不会悄悄改变已有总配置。
- 声音、麦克风与鼠标：调节声音和输入的音量与静音、鼠标速度和指针大小。音频简化为「音量」「输入」两项，自动跟随 Windows 当前默认选择；虚拟声卡同样通过系统控制，不需要在 FC 中重新选择或绑定。
- 桌面面板与快捷操作：半透明、可移动和缩放；双击立即解锁并前置，失焦或 Esc 锁定；支持 Win+D 显示桌面、托盘驻留和全局快捷键。
- 每屏软件菜单与诊断：通过 FC 屏幕菜单集中调节当前屏幕，采集只读诊断信息，为具体型号适配提供依据。
- 手动更新与分类设置：设置按常规、显示器、快捷键、桌面面板、准星、关于与更新分类；主动检查 GitHub 正式版，下载校验后自行选择安装。
- 离线使用与多语言：本地配置和 JSON 分享文件无需在线账户；支持简体中文、繁體中文、English、日本語、한국어、Deutsch、Français、Español。
v0.3.140 新增 USB 设备管理、C3 配网参考程序与认证 Wi-Fi 光照订阅，并提供跟随应用主题的 Fluent 托盘菜单。包含 Windows WMI 内屏亮度与自动调节；实体传感器联动和笔记本仍需实测。提供 Windows x64 离线 Setup.exe 与 MSI。
下载新版 Setup（推荐） · MSI / 校验文件 · v0.3.140 · 版本说明
- 下载并运行 Setup。新安装可选择有写入权限的本地目录，并决定是否随 Windows 启动；成功后点击“启动 FluentControl”。支持离线安装，无需管理员权限，单独 MSI 也继续提供。升级沿用原目录；迁移目录时先卸载再安装，个人配置保留。
- 在外接显示器的实体菜单中开启 DDC/CI，连接后读取设备。
- 为屏幕命名，选择整体或单独控制，保存第一套配置。
- 按需开启桌面面板、快捷键和开机自启动。
主要面向 Windows 11 x64。升级前请从托盘彻底退出旧版本；升级和卸载均保留个人配置。当前正式安装包未做代码签名，Windows 可能显示“发布者未知”。开发分支的后续修复见 更新记录，测试安装包见 Windows build。
v0.3.92 新增系统色温（软件）：按屏调整画面冷暖，一键恢复原曲线，可保存到本机总配置；适用于接口可用的 SDR 内屏或外屏。HDR/自动颜色管理下暂不使用此兼容接口，提供 Windows 夜间模式入口。范围与使用说明。
v0.3.92 新增每屏 Windows HDR 开关：切换后重新检测显示器控制项；与 DDC/CI 独立，Windows 支持 HDR 的内屏也可使用。WMI 笔记本亮度与厂商专有功能尚未接入，实体屏幕切换待本机验证。控制范围与使用说明。
显示器可用功能取决于型号、固件、连接方式和当前模式。HDR、节能模式、转接器及扩展坞可能限制调节；带有音频输出也不一定支持显示器硬件音量遥控。FC 软件菜单已提供，直接打开和导航显示器原厂 OSD 仍需经过验证的型号适配。v0.3.92 提供实验性的本地 OSD 配对助手：自动列出已声明的未知指令，逐次试发并按观察到的效果绑定遥控，支持部分配对和可选文件分享，无需上传。
本地预设、JSON 导入导出已可用。 配置分享站与在线型号适配库尚未部署，在线查询及报告提交暂不可用。计划域名为 fctrl.app，配套网站独立维护于 FluentControl-Web。
| 方向 | 目标 |
|---|---|
| 更好的显示器兼容性 | 持续验证色温、场景模式、HDR 和原厂菜单控制，积累可靠的型号适配 |
| 配置分享与适配库 | 上线型号预设分享、适配查询、诊断提交及审核流程 |
| 更自然的多设备使用 | 改善插拔识别、离线设备管理、外部按键调节后的状态同步 |
| 按场景自动调节 | 探索应用联动、定时配置和更多快捷操作 |
以上是后续方向，未承诺发布时间。详细开发任务和验收条件维护在 agent.md。

FluentControl is a Windows DDC/CI monitor brightness and multi-monitor control app with system volume, input and mouse controls in one Fluent-style interface.
Save a setup for work, gaming or late-night use and recall it when needed. Adjust multiple displays together or individually, and keep frequent controls on a translucent desktop panel.
| Everyday friction | What FluentControl offers |
|---|---|
| Adjusting several monitors means reaching for several sets of buttons | Linked or individual controls with per-display brightness mapping |
| Changing activities requires repeating the same device adjustments | Global profiles for display, audio, microphone and mouse settings |
| Useful monitor settings are difficult to organize, move and reuse | Model-based presets, batch import/export and compatibility checks |
| Frequent controls are spread across several settings windows | One main panel, a tray menu, hotkeys and a desktop panel |
- Monitor controls: brightness, contrast, color presets, RGB, gamma, saturation, picture modes, input source, monitor volume and more, where supported by the hardware.
- Software temperature and HDR: adjust SDR warmth per display, restore original colors and switch HDR where Windows supports it, with clear notices when HDR may restrict picture controls.
- Linked controls across models: adjust different monitor models together. Settings go only to displays that support the selected feature or option, with partial support clearly indicated.
- Global profiles and monitor presets: save a complete device setup or reusable settings for one monitor model. Updates retain offline device settings; editing a library preset does not silently change existing profile snapshots.
- Audio, microphone and mouse: adjust output/input volume and mute, mouse speed and pointer size. Audio is simplified to Volume and Input, following the current Windows defaults, including virtual audio endpoints, without selecting or binding devices in FC.
- Desktop panel and shortcuts: a movable, resizable translucent panel, double-click to unlock and immediately bring it forward, blur or Esc to lock, support for Win+D, tray operation and global hotkeys.
- Per-display software menu and diagnostics: adjust a display through the FC on-screen menu and collect read-only diagnostics for model-specific adaptation.
- Manual updates and organized settings: browse General, Displays, Shortcuts, Desktop controls, Crosshair, and About & updates. Check GitHub stable releases on demand, verify the download, and choose when to install.
- Offline use and eight languages: local profiles and JSON sharing files need no online account. Available in Simplified Chinese, Traditional Chinese, English, Japanese, Korean, German, French and Spanish.
v0.3.140 adds USB device setup, C3 provisioning reference firmware and authenticated Wi-Fi light subscriptions, plus a themed Fluent tray menu. Includes Windows WMI panel brightness and opt-in automation; physical sensor integration and notebook validation remain pending. Windows x64 offline Setup.exe and MSI are available.
Download Setup (recommended) · MSI / checksums · v0.3.140 · Release notes
- Run Setup, choose a writable local folder and whether to start with Windows, then explicitly launch after success. Installation works offline without administrator privileges; standalone MSI remains available. Upgrades keep the existing folder; uninstall and reinstall to move it. Personal settings are retained.
- Enable DDC/CI in your external monitor's physical menu, then let the app read your devices.
- Name your displays, choose linked or individual control, and save your first profile.
- Enable the desktop panel, hotkeys or startup option as needed.
Primarily designed for Windows 11 x64. Fully exit the previous version from the tray before upgrading. Upgrades and uninstallation retain personal settings. The current stable installer is unsigned, so Windows may show an unknown-publisher prompt. Later development changes are listed in the changelog; test installers are available from Windows build.
v0.3.92 adds software color temperature per display, original-curve restoration and local global-profile saving for supported SDR internal or external displays. HDR/auto color management blocks this compatibility interface and offers Windows night light instead. See scope and usage.
v0.3.92 adds per-display Windows HDR switches and rediscover monitor controls after switching. HDR works independently of DDC/CI, including internal panels when Windows reports support. WMI laptop brightness and proprietary OEM controls remain unimplemented; physical HDR switching still needs local verification. See control scope and usage.
Available monitor controls depend on the model, firmware, connection and active mode. HDR, power-saving modes, adapters and docks may restrict adjustments. An audio output does not necessarily provide remote control of the monitor's hardware volume. The FC software menu is available; opening and navigating a monitor's native OSD requires a verified model-specific adapter. v0.3.92 includes an experimental local OSD pairing assistant: automatically discover advertised unknown commands, test them one at a time, bind observed effects and optionally exchange files without uploading or signing in.
Local presets and JSON import/export are available. The sharing service and online adapter catalog have not been deployed, so online lookup and report submission are not available yet. The planned domain is fctrl.app; the companion website is maintained separately in FluentControl-Web.
| Direction | Goal |
|---|---|
| Better monitor compatibility | Validate color presets, picture modes, HDR behavior and native menu controls; build a reliable adapter catalog |
| Sharing and model adapters | Launch preset sharing, adapter lookup, diagnostic submission and review workflows |
| Smoother multi-device use | Improve hot-plug detection, offline device management and synchronization after physical OSD changes |
| Context-aware adjustments | Explore application-triggered profiles, scheduled adjustments and more shortcuts |
These are planned directions without committed release dates. Detailed engineering tasks and acceptance criteria are maintained in agent.md.
These projects inform monitor-control and adaptation research. FC support still depends on validation against the relevant hardware.
