Monitor Control Manager

A lightweight Windows utility for controlling monitor settings via DDC/CI. Adjust brightness, contrast, input source, and power settings directly from your system tray.

.NET 9.0 Platform License

Features

  • System Tray Integration - Clean popup interface accessible from taskbar
  • Multi-Monitor Support - Control all DDC/CI compatible displays
  • Brightness & Contrast - Slider controls with real-time feedback
  • Input Source Switching - Auto-detects available inputs (HDMI, DisplayPort, DVI, VGA)
  • Power Management - On, Sleep, and Off controls
  • Multi-Language - Auto-detects system language (English, Spanish, French, German, Chinese, Japanese, Portuguese, Italian, Hindi)

Requirements

  • Windows 10/11
  • .NET 9.0 Runtime
  • DDC/CI compatible monitor(s)

Note: Most external monitors support DDC/CI, but some laptop internal displays and certain monitors may not support this protocol.

DDC/CI Protocol

The application uses DDC/CI (Display Data Channel/Command Interface) to communicate with monitors through the display cable. This allows software control of settings normally accessed via physical monitor buttons.
