# ControlMyMonitorManagement

A Windows desktop application for controlling monitor settings via DDC/CI (Display Data Channel/Command Interface). Adjust brightness, contrast, power state, and other display parameters across multiple monitors.

## Features

- **Multi-Monitor Support** - Detect and control multiple connected displays
- **Brightness & Contrast Sliders** - Easy adjustment with real-time feedback
- **Input Source Switching** - Switch between VGA, DVI, HDMI, DisplayPort (auto-detected from monitor)
- **Power Management** - Turn monitors on, off, or into sleep mode
- **System Tray Integration** - DellMonitorControl app with taskbar tray popup
- **9 Languages** - Auto-detects system language (en, es, fr, de, zh, ja, pt, it, hi)

## Requirements

- Windows OS
- .NET 7.0 SDK
- DDC/CI compatible monitor(s)

## Build

```bash
# Clone the repository
git clone https://github.com/yourusername/ControlMyMonitorManagement.git
cd ControlMyMonitorManagement

# Build the solution
dotnet build ControlMyMonitorManagement.sln

# Run the main application
dotnet run --project ControlMyMonitorManagement/ControlMyMonitorManagement.csproj

# Run the Dell-specific application (with system tray)
dotnet run --project DellMonitorControl/DellMonitorControl.csproj
```

## Project Structure

| Project | Description |
|---------|-------------|
| **ControlMyMonitorManagement** | Main WPF application with full UI |
| **DellMonitorControl** | Lightweight app with system tray integration |
| **Library** | Core business logic and DDC/CI operations |
| **CMMModel** | Data models for monitor status |
| **CMMService** | Service layer interfaces |
| **Language** | Localization support |
| **Tester** | NUnit test project |

## Common VCP Codes

| Code | Name | Values |
|------|------|--------|
| D6 | Power Mode | 1=On, 4=Sleep, 5=Off |
| 10 | Brightness | 0-100 |
| 12 | Contrast | 0-100 |
| 60 | Input Source | 1=VGA, 3=DVI, 15=DisplayPort, 17=HDMI |

## How It Works

This application uses DDC/CI protocol to communicate with monitors through the display cable (HDMI, DisplayPort, DVI, VGA). DDC/CI allows software to send commands directly to the monitor's firmware to adjust settings that would normally require using the monitor's physical buttons.
